A Japanese YouTuber Said He Would Not Let Fukushima University Touch Radiation Research. Can Entrance Exam Scores Measure a University’s Research? Japanese Reactions

The Japanese YouTube channel wakatte.TV, which built 770,000 subscribers on mocking universities by entrance exam difficulty, said of radiation research that it would not want Fukushima University touching it. The university's president issued a statement on September 1, 2026 and the channel deleted the video and apologised. This article explains what hensachi actually measures, who staffs the university's radiation research institute, how Japanese law decides which institutions may handle radioactive material, and adds Japanese Reactions from X, where two sitting mayors drove the response.

Key Points

ใƒปOn August 28, 2026, the Japanese YouTube channel wakatte.TV published a campus visit video about Fukushima University titled around the claim that it ranks last among national and public universities. When a student described radiation research as something particular to Fukushima, presenter Fumihiro Takada said that he would not want Fukushima University touching it. According to the statement published on the Fukushima University website on September 1, 2026 under the name of President Koji Sano, the university called its work on the nuclear disaster and environmental radioactivity important research that verifies Fukushima’s experience scientifically and returns the findings to Japan and the world.

ใƒปThe channel had run for nine years on an announced premise of satirising Japan’s credentialist society, with Takada playing a character who treats university rank as everything. Takada himself entered Kyoto University’s economics faculty and later withdrew, so in the terms of Japan’s education categories his completed level is upper secondary school. That mismatch gave viewers room to read the format as a joke about the hierarchy itself. This time the mockery moved from the name of a university to the competence of the people doing research there.

ใƒปWhether an institution may handle radioactive material in Japan is decided by licensing, registration and inspection under the Act on Regulation of Radioisotopes, not by admissions difficulty. According to the Fukushima University Radiation Hazard Prevention Regulations as in force from April 1, 2025, the university must appoint a licensed radiation protection supervisor, register every worker who enters a controlled area, and repeat training annually and health checks every six months. The staff list published by the Institute of Environmental Radioactivity shows a deputy director seconded from Nagasaki University and researchers from Ukraine, Algeria and Nigeria.

Fukushima University Issues a Presidential Statement and wakatte.TV Deletes the Video

wakatte.TV, a Japanese YouTube channel built around academic credentials, published a campus visit video about Fukushima University on August 28, 2026. According to ITmedia NEWS reporting on September 2, 2026, the channel has more than 770,000 subscribers and the video was titled around the questions of whether the entrance exam is too easy and whether the university ranks last among national and public institutions. In the video a student described radiation research as something particular to Fukushima. Presenter Fumihiro Takada replied that radiation and nuclear power are a critically important energy issue, and that he would not want Fukushima University touching it.

According to press reporting, the operators first made the video private as criticism spread, then republished it with an on-screen caption attached to the passage in question. As of the evening of September 1, 2026 it was again unavailable.

Fukushima University published a statement on its official website on September 1, 2026 under the name of President Koji Sano. The statement described research on the nuclear disaster and environmental radioactivity as important work that verifies Fukushima’s experience scientifically and returns the results to Japan and abroad, and said that students and staff must not have their dignity injured. It also asked people to refrain from abuse directed at specific individuals.

wakatte.TV published an apology on X the same day. According to ITmedia NEWS reporting on September 2, 2026, the statement said the video was not intended to mock or discriminate against the earthquake or the nuclear accident, said that consideration for people’s aspirations had been decisively lacking, and announced the deletion of the video and measures to prevent a recurrence. Fukushima University told Bengo4.com News that it had not been in contact with the channel and was not planning any deletion request or protest, and that no application had been filed to film on campus.

Yuki Baba, mayor of Fukushima City, posted his regret about the video on X on September 1, 2026, and Hiroyuki Uchida, mayor of Iwaki City, did the same on September 2.

Naohiro Hayashi, the founder of the cram school chain Takeda Juku, where Takada is an employee of the operating company, defended the channel on September 2, 2026. According to Tokyo Sports reporting that day, Hayashi wrote that Takada had only meant to tease a university whose entrance scores are not especially high and that the clip had been maliciously edited. In a separate post Hayashi asked whether universities with low entrance scores can really do advanced research. That post carries a Community Note, the reader-written context feature on X, citing the university’s environmental radioactivity institute.

What Hensachi Measures, and What Fukushima University Has Been Doing Since 2013

Hensachi is a standardised score showing where a test taker sits within the population that sat a particular practice exam, with the average fixed at 50. It is produced by private cram schools, not by the state, so the number depends on which company’s mock exam it came from. Japanese readers treat it as the everyday shorthand for university rank.

A channel that announced itself as satire

wakatte.TV began in 2017 as a street interview channel. Its recurring formats involve stopping passers by, or students inside university campuses, and turning the hierarchy of entrance exam difficulty into a joke. The two presenters are Fumihiro Takada and a co-host who entered Waseda University after a year spent retaking the entrance exams.

According to the Japanese Wikipedia entry on the channel and subsequent press coverage, the channel described itself as satirising Japan’s credentialist society, framed for high school students as a warning not to become adults like this, with Takada cast as a black-humour character who treats academic rank as everything.

Takada’s own record is what made the framing work. He entered the economics faculty of Kyoto University on his first attempt, took leave from April 2017, joined A.ver, the company that operates Takeda Juku, in October of that year, and later withdrew from the university. Because he did not graduate, his completed level of education is upper secondary school. A person who insists that credentials are everything, while holding no university degree himself, is what left viewers room to read the format as performance.

Criticism did not start with this video. In 2020 Takada was criticised for a remark about bread made by a high school graduate, delivered to a bakery worker he met in Hiroshima. On August 3, 2026, Professor Seiki Okazaki of Kyushu University posted on X that he felt strong revulsion at a format that mocks students by entrance exam difficulty, and according to reporting by Yahoo News expert contributors the post passed 5.9 million impressions by the evening of August 4.

Hayashi replied on August 7, 2026 asking why a national university professor should demand that a private video be taken down, and an exchange followed. On August 18, 2026, according to the same expert reporting, a video filmed at Tokyo Metropolitan University treated a nuclear safety engineering programme lightly on the grounds of its entrance difficulty.

What the Institute of Environmental Radioactivity actually is

The Institute of Environmental Radioactivity at Fukushima University was established on July 1, 2013 in response to the accident at the Fukushima Daiichi nuclear power plant. According to the institute’s own website, it was founded to help resolve an accident that released large quantities of radioactive material into the environment and to share the scientific findings internationally. It is organised into five divisions and fifteen fields, and its graduate programme in environmental radioactivity, offered at both master’s and doctoral level, is described as the first of its kind in the world.

The work is not the same field as nuclear engineering, which deals with reactors and fuel. The institute studies how radioactive caesium released into forests, rivers, estuaries and the sea moves through those systems and accumulates in trees and fish, including comparative work with Chernobyl. In June 2026 the institute published research, led by a doctoral student as first author, on what drives variation in dissolved caesium concentrations in the seawater of Matsukawa-ura, a lagoon in Soma, Fukushima Prefecture.

The people doing that work are not drawn only from Fukushima University’s own graduates. According to the staff list published by the institute, one of its deputy directors holds a concurrent post as a professor at Nagasaki University, and the faculty includes researchers from Ukraine, Algeria and Nigeria.

The institute holds agreements with Hiroshima University, Nagasaki University, the Japan Atomic Energy Agency, France’s Institute for Radiological Protection and Nuclear Safety and Colorado State University in the United States, among others. According to the institute’s news page, it hosted a special seminar on July 13, 2026 with speakers including a division head from the International Atomic Energy Agency.

Handling radioactive material is decided by law and registration

Whether a Japanese university may handle radioactive material is decided by a licence from the Nuclear Regulation Authority under the Act on Regulation of Radioisotopes. A licence holder must appoint a radiation protection supervisor holding a national qualification, meet facility standards, designate controlled areas, measure doses, provide training and arrange health checks, and submit to on-site inspection by the authority.

Fukushima University implements that framework through internal rules called the Radiation Hazard Prevention Regulations. Anyone entering a controlled area must be registered as a radiation worker, and registration follows a health check that returns a satisfactory result. Experiments require a plan submitted for approval, training is repeated at intervals of no more than one year, and health checks are repeated every six months.

Workers who breach the regulations, or who are judged to lack the competence to handle the material, can have their registration cancelled or suspended. Theft or abnormal leakage must be reported to the Nuclear Regulation Authority immediately.

On the video’s claim about ranking last among national and public universities, no public indicator supports it. Hensachi is a private measure of relative position within the group that sat a given cram school’s mock exam. According to Kawaijuku’s Kei-Net border projections for the 2027 entrance cycle, Fukushima University’s border hensachi runs from 40.0 to 50.0 depending on the faculty.


Can Entrance Exam Difficulty Measure a Research Institute?

The self-deprecating device that stopped working

For nine years the channel’s mockery came with a built-in escape route: the person doing the mocking holds no university degree himself. A man who says that high school graduates are inferior is, in the official categories, a high school graduate. While that structure held, viewers could laugh at the person enforcing the hierarchy as much as at its targets, which was one of the things that let the format be read as a joke about credentialism rather than an endorsement of it.

This time the device did not engage. A man who passed the Kyoto University entrance exam had, in effect, denied the professional competence of people doing research at Fukushima University, and the retort that he is a high school graduate himself no longer lands. The target had moved from the name of a university to what kind of research can be done there, and the structure of the joke changed with it.

The Fukushima video was also not an isolated slip. In early August 2026 a Kyushu University professor criticised the format itself, and the founder of Takeda Juku answered him on X. Reporting then placed a similar moment on August 18, 2026, when a video at Tokyo Metropolitan University treated a nuclear safety engineering programme lightly because of its entrance difficulty. Comparable scenes continued after the format itself had been publicly criticised.

Why the demand for competence in dangerous research is a fair question

Put the defence in its strongest form and it becomes a serious question. Radiation and nuclear technology are fields where failure reaches society at large, so the institutions and researchers handling them should be held to a high standard of competence. Hayashi wrote on X that universities with low entrance scores probably cannot do advanced research, and in the same post asked that such national and public universities receive a smaller share of subsidies.

The question itself is not unreasonable. No country lets anyone handle legally regulated hazardous material at will, and requiring evidence of competence from those who do is a normal instinct. It is also true that strong students, established researchers and research funding tend to concentrate at leading universities, so the claim that selection at entry and research strength may correlate has some basis. The idea that funding should be weighted by results has genuine support.

Japan already does that weighting. According to the Ministry of Education documents on performance-based allocation for the 2026 fiscal year, 100 billion yen of the national university operating grants is distributed on the basis of results, with allocation rates ranging from 75 to 125 percent, using eleven indicators including research output per full-time academic, competitive grant income per academic, and the proportion of early-career researchers.

Dismissing the underlying concern as simple prejudice would be a weak answer. The argument turns on the next step. Can the entrance hensachi of an undergraduate faculty serve as the instrument for measuring that competence? None of the eleven indicators in the funding formula has anything to do with admissions difficulty.

Why entrance exam difficulty does not measure a research institute

Stated as a chain of reasoning, the claim runs in four steps: Fukushima University’s entrance hensachi is not high, therefore the average academic ability of its students is below that of the University of Tokyo or Kyoto University, therefore its capacity to conduct advanced research is lower, therefore important fields should not be entrusted to it. Given what hensachi measures, the first two steps are unremarkable.

The break comes at the third. University research is not carried out by the eighteen year olds who passed this year’s entrance exam. It is carried out by researchers who have completed doctorates, by people recruited from other universities and research institutes, and by specialist technical staff.

At the Institute of Environmental Radioactivity, a professor from Nagasaki University serves as deputy director and the faculty includes researchers from Ukraine, Algeria and Nigeria. Graduate students are part of the workforce too, but the group that passed the undergraduate entrance exam and the body of researchers at the institute are not the same population, and externally recruited researchers make up much of it.

The opposite claim, that hensachi and research strength have nothing to do with each other, is equally overstated. The overall research strength of the University of Tokyo and Kyoto University is hard to deny. But a possible correlation and the power to dismiss one field at one university on the basis of a score are different things. From the premise that Tokyo’s students average higher test scores, nothing automatically follows about who does better environmental radioactivity research in Fukushima.

Research output and safety management are two different measurements

Testing the claim seriously would mean separating three questions. Is the institute producing research? Is it managing radioactive material safely? Has there been a serious accident or misconduct? A world-class researcher with sloppy safety practice is dangerous, and an institution that publishes nothing remarkable can still handle radioactive material exactly as the rules require.

On output, the institute has published on caesium movement in the environment and accumulation in fish since its founding in 2013, and holds agreements with the IAEA and with research bodies in France, Belgium and the United States.

On safety, the university’s regulations provide for the appointment of a radiation protection supervisor, registration and health screening of workers, prior approval of experimental plans and immediate reporting to the Nuclear Regulation Authority, including a clause cancelling the registration of workers judged to lack competence. No serious accident or misconduct appears in the published record.

The logic of the system is not that a high score earns the right to handle the material. It is that people, facilities, procedures and oversight meeting the statutory standard earn it. Holding a licence proves nothing about research quality, and papers and agreements do not by themselves establish that an institute is excellent. But with nothing shown against any of the three, the burden of evidence sits with whoever says the material should be kept away.

What Fukushima adds, and what the apology did not explain

There is no need to assert what anyone intended. wakatte.TV denies any intent to mock the disaster or the accident, and some viewers who watched the whole video came away thinking the target was the entrance score rather than the disaster area.

The result was still that a disaster area, a local university that has spent fifteen years researching the aftermath, the word radiation and the phrase about not letting them touch it all appeared in the same frame.

The mayors of Fukushima City and Iwaki City responded in turn, and the Iwaki mayor disclosed that he had previously served as an executive director and administrative head of Fukushima University before expressing his regret. The social context is nothing like the channel’s older material about which private universities count as low ranking.

There is excess on the critical side as well. The Kyushu University professor asked that closing the channel be considered, and a demand to erase an entire programme over an inappropriate remark invites an answer grounded in freedom of expression. The university’s own statement paired its defence of students with a request to refrain from abuse, which suggests concern that criticism could turn into a different kind of attack.

The apology says that clumsy wording conveyed something other than what was meant. The part about not intending to mock the disaster is intelligible. What remains thin is any account of what the original meaning was. If it was that important research should be entrusted to strong universities, then the relationship between entrance scores and research capacity is exactly what is at issue, and that is the claim least able to survive examination.

Between no connection at all and the Takeda Juku question

Takada is not only a YouTuber. He is an employee of A.ver, the company that operates Takeda Juku, where his role covers public relations and the quality of instruction across the chain. In a blog post he wrote in September 2017, he recorded that the channel’s name was built on a pun combining Takeda Juku’s word for junior staff with the Japanese word for understanding.

In April 2026 A.ver issued a press release promoting a baseball event it sponsored, announcing that Takada of wakatte.TV would appear.

At the same time, the videos are reported to carry a notice stating that the channel is unrelated to Takeda Juku and A.ver. If that means the company does not own or operate the channel, the notice and the facts can both be true. There is no basis for calling wakatte.TV a Takeda Juku programme.

Even so, with the central figure employed by the operating company, the channel’s name derived from the chain, and the company using him in its own promotion, separating the channel entirely from the corporate reputation is difficult. The Kyushu University professor’s criticism in August turned on that relationship. How should it be judged when someone working in education turns anxiety about credentials into entertainment for exam candidates? That question reaches past this incident into how the channel was built.

How outrage converts into views

Nine years of this format rest on a mechanism: the more a video provokes viewers’ own anxieties about credentials, the more easily it spreads. YouTube advertising revenue follows views and watch time, and the sharpest single line is the one most likely to be clipped and circulated. A format under that pressure tends to be pushed toward stronger language over time, and a title claiming last place among national and public universities can be read as part of that drift.

The mechanism is not driven by the supply side alone. Viewers who enjoyed it as the usual routine were there, and the presenter built the act with the retort about his own lack of a degree already priced in. This was content sustained by demand, and blaming the producers alone does not change the structure.

The same incentive operates on the nuisance streamers who cause problems through unauthorised filming and disruption of businesses. wakatte.TV, which films consenting street interviews, is a different case, but the economics of provocation are the same. While that incentive holds, the target of the mockery moves more easily from the name of a university to a faculty, and from a faculty to a field of research.


Japanese Reactions to the wakatte.TV Fukushima University Controversy

What follows is a sample of widely shared posts on X, not a measure of Japanese public opinion. The posts are in Japanese, and translations are given here in English.

The striking feature of this story is who carried it. The three most widely shared individual posts came from elected officials in Fukushima Prefecture, and one of them had worked inside the university itself.

A video on wakatte.TV that appears to mock Fukushima University’s environmental radioactivity research and other work has become a talking point.

I previously served as an executive director and administrative head at Fukushima University, and speaking from that position as well, I find this video genuinely very disappointing.

Fifteen years have passed since the Great East Japan Earthquake and the nuclear accident. At Fukushima University, students and staff have put down roots in the region and continued their research and teaching in earnest, including environmental radioactivity research, for the sake of Fukushima’s recovery.

Hurting those students and staff, or mocking their effort itself, is something that should not happen.

President Koji Sano has issued a comment, and as someone who worked at Fukushima University I strongly share that sentiment.

Hiroyuki Uchida, Mayor of Iwaki City, September 2, 2026. The post drew about 34,900 likes and 2.44 million views, the largest reach of any individual post on the story.

The mayor of Fukushima City had posted the night before, and his post is the one that separates the criticism from the pile-on.

This is about the video featuring Fukushima University.

I am not denying the value of a programme built around students, or of conveying a university’s appeal as entertainment.

At the same time, an expression that appears to mock the Great East Japan Earthquake, the nuclear disaster and research on radiation is not something I can let pass.

Since the disaster, students and researchers at Fukushima University have built up serious research on radiation, the environment and recovery, as questions that Fukushima above all must face.

There has been an explanation that there was no intent to mock. But the absence of intent does not make any expression permissible. Those who publish have a responsibility to imagine how their words reach the people concerned.

I also note that the video has already been deleted and an apology given. That is precisely why I hope this becomes an occasion for deeper understanding, rather than leading to new abuse directed at anyone.

Yuki Baba, Mayor of Fukushima City, September 1, 2026. About 23,600 likes and 1.89 million views.

The defence came from inside the industry, and it is the post that moved the argument onto the ground this article is about. Naohiro Hayashi founded Takeda Juku, the cram school chain whose operating company employs Takada.

Universities with low hensachi probably cannot do advanced research, can they?

I would like national and public universities with low hensachi to receive a smaller share of subsidies.

Naohiro Hayashi, founder of Takeda Juku, September 2, 2026.

The numbers on that post tell their own story. About 545 likes against 820 reposts and 287 replies, a pattern that marks circulation driven by objection rather than agreement, and it carries a Community Note, the reader-written context feature on X.

Advanced research is conducted at national and public universities with low hensachi as well, and Fukushima University is advancing leading research on the environmental behaviour of radioactive materials at its Institute of Environmental Radioactivity. Subsidies for national and public universities are not based on hensachi alone.

Community Note attached to the post above, citing the institute’s website among its sources.

A prefectural assembly member relayed what students had told him, without identifying them.

On the wakatte.TV matter, the content was so bad that I do not even feel like commenting on it.

Today I heard from current Fukushima University students.

Their words: discomfort at the university and its students being consumed as content. If Fukushima University does not confront the nuclear accident, who will. Is this not simply a failure to do the homework.

At Fukushima University, researchers and students take responsibility for confronting the heavy questions of the nuclear accident and Fukushima’s recovery.

Fukushima Prefectural Assembly member Kohei Watanabe, September 2, 2026. About 15,900 likes and 1.1 million views.

Two things are worth noting about the shape of this response. The first is that the volume came from local public office rather than from national commentary, which is why the loudest note is regional rather than partisan. The second is that the subject shifted with time. On August 31 the conversation was still about establishing what had happened, on September 1 it peaked around the university statement and the apology, and from September 2 the centre of gravity moved to whether entrance scores measure research capacity at all. Posts defending the channel exist but are few, and the most visible defence functioned as a second wave of the controversy rather than a resolution of the first.


Where a Single Ruler Stops Reaching

There is a reasonable question inside all of this about who should be trusted with advanced and hazardous research. It is also not true that entrance difficulty and the calibre of the people at a university are wholly unrelated.

Even so, concluding that Fukushima University should be kept away from the material, without examining the environmental radioactivity research it actually does, the statutory safety system it operates under, its collaborations at home and abroad, or thirteen years of activity, does not rest on sufficient grounds. Nobody has to prove the institute is excellent. A single counterexample that a score cannot dismiss is enough to show where the ruler stops.

This was not simply a story about one tasteless remark. It was the moment when the single ruler the channel had used for nine years was carried into a different domain, university research, and the places it does not reach became visible.

The error of treating entrance difficulty as a proxy for research capability is not confined to this case. It recurs in how university rankings are read, in performance-based weighting of operating grants, and in which institutions qualify for tuition support programmes.

What hensachi measures is where someone stood, at eighteen, within the group that sat a mock exam. Everything after that has to be measured with different instruments. What this episode shows is the risk of discussing rank without holding any of them.


Frequently Asked Questions

What is hensachi, and does it measure a university’s research quality?

Hensachi is a standardised score showing where a test taker sits within the population that sat a particular cram school’s mock exam, with the average set at 50, and it does not measure research quality. It describes the relative academic position of eighteen year old applicants at the point of entry, whereas university research is conducted by doctorate-holding researchers, staff recruited from other institutions and specialist technicians. At Fukushima University’s Institute of Environmental Radioactivity, the published staff list shows a deputy director holding a concurrent professorship at Nagasaki University and researchers from Ukraine, Algeria and Nigeria.

Did Fukushima University protest to wakatte.TV or demand the video be removed?

No. Fukushima University published a statement under the name of President Koji Sano on September 1, 2026, and told Bengo4.com News that it had not been in contact with the channel and was not planning any deletion request or protest. The same reporting records that no application had been filed to film on campus, and that the university asked its own students to refrain from arguing back on social media.

Who decides whether a Japanese university can handle radioactive material?

The Nuclear Regulation Authority does, through licensing under the Act on Regulation of Radioisotopes, and admissions difficulty plays no part in it. A licence holder must appoint a radiation protection supervisor holding a national qualification, register every worker entering a controlled area, obtain approval for experimental plans, repeat training annually and health checks every six months, and report theft or abnormal leakage immediately. The Fukushima University Radiation Hazard Prevention Regulations, as in force from April 1, 2025, implement each of those requirements internally.

How did Japanese social media react to the wakatte.TV Fukushima University video?

Overwhelmingly critically, and the reaction was led by local elected officials rather than national commentators. On X the three most widely shared individual posts came from the mayor of Iwaki City, who disclosed that he had previously served as an executive director of Fukushima University and whose post drew about 34,900 likes, the mayor of Fukushima City with about 23,600, and a Fukushima prefectural assembly member with about 15,900. The most visible defence, from the founder of the cram school chain that employs the presenter, drew about 545 likes against 820 reposts and carries a Community Note citing the university’s environmental radioactivity institute.
