Key Points
ใปOn September 28, 2026, Tetsuya, the leader of the Japanese YouTube group Tokai On Air, unveiled the mansion he built in Okazaki, Aichi Prefecture, after about five years of planning. Neither the building cost nor a breakdown of his income has been disclosed.
ใปA YouTube video reaches millions of viewers with almost no additional production work, and the attention it gathers is sold to advertisers and shared with creators. Face-to-face work such as caregiving has a ceiling on how many people one worker can serve at once.
ใปMarkets price scarcity and reach, not necessity, and the rewards concentrate in a very small group at the top. Essential work such as care and childcare, with a headcount ceiling and government-set prices, does not take the same market shape.

Tetsuya Shows Off the Home He Planned for Five Years
On the evening of September 28, 2026, Tetsuya, leader of the YouTube group Tokai On Air, posted a video tour of his newly built home in Okazaki, Aichi Prefecture, on his personal channel. The tour runs for over an hour. According to Japanese entertainment media, planning began in 2021 and the house took about five years to complete.
According to those reports, the single-story house is finished in orange, Tetsuya’s color within the group. It has parking for about ten cars, a front door with palm-vein authentication, and custom glass panels reported to cost 5 million yen each. It also includes rooms for filming, editing and game streaming.
His wife, the TV personality Minami Minegishi, also appears in the video and says that her husband covers all the costs of the new home, Sports Nippon reported. The building cost, the source of the funds and a breakdown of Tetsuya’s income have not been made public.
Tokai On Air is a six-member group based in Okazaki. Its main channel was created in October 2013. As of October 1, 2026, the channel had 7.26 million subscribers and about 16.9 billion total views, according to its YouTube page.

How One Video Reaches Millions of People
Tokai On Air is a six-member YouTube comedy and variety group based in Okazaki, a regional city in central Japan, with 7.26 million subscribers to its main channel as of October 1, 2026. Its videos are mostly filmed around the city, and all six members still live there, according to the Okazaki Tourism Association.
From six friends in a regional city to a national audience
The group has worked out of Okazaki since it created its main channel in 2013. Fans began visiting places they had seen in the videos. The city’s tourism association named the six its first “Okazaki Tourism Ambassadors” in 2016, and fiscal 2026 is their eleventh year in the role.
According to a joint study released by the City of Okazaki and the talent agency UUUM in September 2026, Tokai On Air’s economic ripple effect on the city over the ten years from 2016 to 2025 was estimated at 36.91 billion yen, most of it from tourism spending by visiting fans. Tetsuya was reported to have named building a mansion in his hometown as a goal in a 2019 video with HIKAKIN, one of Japan’s best-known YouTubers.
Its subscriber count is equivalent to roughly one seventeenth of Japan’s population, reached without owning a TV station or a national newspaper.
A hairdresser serves one client an hour; a video can serve three million
A hairdresser who works for an hour can usually cut one person’s hair. Ten times as many customers means ten times as many hours. Restaurant staff, care workers and nursery teachers all work under the same kind of ceiling.
Video works differently. Suppose a 20-minute video is watched by three million people. The creator does not have to make it three million times. If the audience grows tenfold, the cost of filming and editing stays almost the same. Economists call the extra cost of serving one more customer the marginal cost, and for a video it is close to zero.
The British economist Alfred Marshall noted in his *Principles of Economics* that a singer’s earnings were limited by the number of people a human voice could reach. Recording, broadcasting and then the internet removed that limit step by step.
Viewers pay nothing, so where does the money come from?
Most people who watch Tokai On Air pay the group nothing directly. The money comes from advertisers, who are buying the viewers’ eyes and time rather than the video itself.
If three million people each watch a 20-minute video, about one million hours of human attention gather around a single upload. Advertisers buy slots inside that time, and YouTube shares the revenue with the creator.
According to YouTube’s Help Center page on partner earnings, creators receive 55% of the net revenue from ads shown on long-form videos on the watch page, while Shorts use a separate pool with a 45% share. That share is the creator’s business revenue. Equipment, staff and taxes come out of it before anything becomes personal income.
| Stage | What happens |
|---|---|
| 1. Viewing | Viewers watch a video and pay nothing |
| 2. Ad inventory | The time they spend creates slots for ads |
| 3. Ad spending | Advertisers buy those slots and pay YouTube |
| 4. Revenue share | YouTube passes 55% of net ad revenue on long-form videos to the creator |
| 5. Spillover | Popularity extends into sponsorships, merchandise, events and books |
Compiled from YouTube Help, “YouTube Partner earnings overview.” Revenue shares can differ under individual contracts.
In 1971, the economist and cognitive scientist Herbert A. Simon observed that a wealth of information creates a scarcity of the attention needed to consume it. The idea is now known as the attention economy. Seen this way, a YouTuber sells not the video but the attention the video collects.
Water is more useful than diamonds, yet cheaper
In *The Wealth of Nations* (1776), Adam Smith wrote that nothing is more useful than water, yet it will buy scarcely anything, while a diamond has little use but can be exchanged for a great quantity of goods. This is known as the paradox of value. Later economists explained it through the value of one more unit: water is plentiful, so one more glass is worth little, while diamonds are scarce.
Nursing, caregiving, childcare, cleaning and farming directly sustain life. Online entertainment fills people’s leisure time. In Smith’s terms, the first group sits on the water side and the second on the diamond side. Prices move with scarcity and the number of buyers, not with how necessary something is.
Why “Unnecessary” Work Can Out-Earn Essential Work
Tetsuya’s home is an entry point for asking how much work that nobody strictly needs can pay. Because neither its cost nor his income is public, what follows looks at the conditions under which money flows to entertainers rather than to essential workers, not at the house itself.
Many people need care, and that need is far more urgent than any need for entertainment. Yet what can be paid for care is capped by household budgets and public funds. Entertainment is a small “I want to enjoy this” for each person, but millions of people can pay for it, and advertising gathers those small payments into the hands of one creator. Markets respond not to how urgent a need is, but to how many people can pay and whether a mechanism exists to collect those payments.
Why do small differences in popularity become huge income gaps?
In his 1981 paper “The Economics of Superstars,” the economist Sherwin Rosen explained why a few people earn enormous sums with two conditions. Watching a second-rate performer many times is not a substitute for watching a first-rate one once, and a single performer can serve a large audience with the same effort. When both hold, small differences in talent are magnified into large differences in earnings.
In the past, the funniest person in Okazaki could entertain a few dozen or a few hundred people nearby. Broadcasting carried performers beyond their region, and the internet carried them across borders. The wider the reach, the more viewers choose the very best from free options, and the less reason they have to watch the second-best. Even if two creators were rated 100 and 95, Rosen’s logic allows their incomes to differ by a factor of dozens.
Charging each of three million viewers 1,000 yen would be nearly impossible. Advertising collects a few yen of value from each of them without the viewer feeling any payment. Popularity then extends into sponsorships, merchandise, events and books, and becomes a form of capital in itself.
This mechanism barely works for anyone outside the top. According to Mathias Bรคrtl’s 2018 study in the journal Convergence, which analyzed a sample of YouTube data from 2006 to 2016, on average about 85% of all views went to 3% of channels. According to Goldman Sachs Research’s April 2023 report, only about 4% of the world’s roughly 50 million creators earn more than $100,000 a year.
According to YouTube’s official blog post of August 2026, from February 2027 creators newly applying for ad and Premium revenue sharing will need 8,000 hours of valid watch time on long-form videos over the previous 365 days (or 20 million Shorts views over 90 days). Existing partners are not affected, but the entrance for newcomers narrows further.
Tokai On Air’s income comes not from being YouTubers but from being near the top of a market measured in millions. Near-zero copying costs are one condition. Advertiser demand, a recommendation system that surfaces the videos, and personalities that other creators cannot replace all have to come together.
Why essential work does not take the same shape
A care worker cannot look after a million people at once. If the number of users grows tenfold, the number of staff has to grow almost tenfold too. Revenue has a headcount ceiling, so no amount of skill lets one worker’s pay jump by an order of magnitude.
The second reason is that providers cannot set their own prices. Kaigo hoshu, the fee schedule for long-term care services, is set by the national government, and the prices for licensed childcare are also fixed by the government as official prices. A shortage of workers does not push fees up the way a market price would, and any pass-through to wages has to go through a revision of the fee schedule. According to Japan’s 2025 Basic Survey on Wage Structure, scheduled monthly earnings for nursery teachers and care workers in facilities were about 80% of the average for all general workers (279,200 yen and 262,900 yen against 340,600 yen).
Face-to-face work can pay well. In the same survey, doctors’ scheduled monthly earnings exceeded 1 million yen, about three times the average, because licensing and limits on training places restrict entry and years of training make them hard to replace. In practice, earnings depend on a combination of how many people the work reaches, how hard the worker is to replace, and whether the worker is in a position to keep what is earned. Top YouTubers sit where all three come together.

Can a YouTuber deduct a mansion by filming it?
YouTubers have an unusual ability to turn consumption into production. When an office worker buys an expensive watch, it is spending. When a popular YouTuber films the unboxing, it can become content watched by millions. The same applies to trips, cars and houses, which is where the idea that “anything you film is a business expense” comes from.
Under Japan’s Income Tax Act, the test is not whether something appears on camera but whether the spending was needed to earn the income, and, for items also used privately, whether the business share can be clearly separated. If it cannot, it is not deductible.
Expensive items cannot be fully deducted in the year of purchase either. As a rule, assets of 100,000 yen or more that are used for years are depreciated over their useful life. According to Japan’s National Tax Agency, items between 100,000 and 200,000 yen can be written off evenly over three years, and blue-return filers can expense assets under 400,000 yen at once if acquired from April 2026. For a home that doubles as a workplace, the basic approach is to separate the part of the building actually used for the business, based on how it is used, and depreciate only that part. Land and living space do not qualify.
A deduction is not a refund. It only reduces the income on which tax is calculated. If a 1-million-yen purchase were fully deductible for someone with a combined income and residence tax rate of half, the tax saved would be about 500,000 yen, and the rest still comes out of that person’s pocket.
According to the National Tax Agency, it conducted about 1,150 field audits of individuals earning from online advertising, digital content and similar new business areas in the year from July 2024, finding 18.4 billion yen in unreported income. This article does not discuss Tetsuya’s own tax affairs.
Is it fair for entertainers to earn more than essential workers?
Resentment toward people who earn large sums from entertainment rests on a real situation: nursing, care and childcare remain understaffed, and because their prices are set with public money, the issue reaches society as a whole. In 2009, the British think tank the New Economics Foundation estimated that hospital cleaners generate more than ยฃ10 of social value for every ยฃ1 they are paid. Its method has been disputed, but the sense that the most necessary work is the worst paid has long been put into numbers.
The creators have their own case. No one is forced to watch, and 7.26 million subscribers chose to spend their own time. Creators bear the upfront investment in equipment, studios and editing teams, and those teams are jobs. They also carry the risk of falling ad rates, demonetization and public backlash, and behind each creator at the top stands a large majority who made the same effort and earned nothing.
Both views have grounds. That market prices and social necessity are measured on different scales is as far as an explanation of the market can go. How far to close that gap through taxes and institutions is a choice for society, not for the market.

[Five Long Years] Tetsuya’s new home is finally complete! A first-look special at a jaw-dropping mansion packed with everything he cared about!
Tetsuya (Tokai On Air), September 28, 2026 (roughly 20,800 likes, translated by Sekahan)
The largest share of reactions was admiration and envy. Posts spoke of a “YouTube dream,” and many noted that the house did not come across as a show of new money. The most-liked reaction we found, from the evening of September 29, was in that vein. It is a long post, and the translation below covers only the part displayed in the preview.

Tetsuya has seriously made almost every guy’s dream come true.
He’s stuck with his friends from high school the whole time,
married the idol he’d been a fan of since he was a kid,
made Okazaki famous and became a tourism ambassador,
a ridiculously cool sports car, and a mansion that’s practically a facility.
He has all of this, and yet there’s no nouveau-riche vibe or bragging about success…
X user, September 29, 2026 (roughly 14,300 likes, translated by Sekahan)
The debate this article examines also surfaced. A post by someone presenting herself as a firefighter’s wife set her husband’s take-home pay against a mansion built by “someone whose job nobody would miss,” and was later deleted. What spread more widely than the original complaint was a reply to it, from an architect who gives home-design advice.

About Tetsuya’s mansion:
the person who quote-posted “my firefighter husband takes home X yen while someone whose job nobody would miss is building a mansion” deleted it, huh…
I get why you’d want to say it.
But money gathers where people gather.
People want to spend money on things that are fun.
That’s just how people are.
And Okazaki, Tokai On Air’s hometown, has seen an economic effect of 36 billion yen.
X user (architect), September 30, 2026 (roughly 7,300 likes, translated by Sekahan)
The 36 billion yen figure in that post appears to be a rounding of the 36.91 billion yen ten-year estimate released by the City of Okazaki and UUUM on September 17, 2026. That estimate is an economic ripple effect, mostly tourism spending, and not sales or tax revenue.
Across the posts we found, criticism of Tetsuya himself was rare. When the “essential workers earn less” argument came up, it was usually answered by others saying that money follows audiences, or that the complaint was aimed at the wrong person. The voices that did take the side of essential workers mostly asked for those jobs to be better rewarded rather than blaming the YouTuber. These observations are based on searches at one point in time and do not measure the overall balance of opinion.
The Gap Between Necessary Work and Well-Paid Work
Looking only at the house in Okazaki, it seems puzzling that posting videos could pay this much. Divided among millions of viewers, the economic value each person generated is tiny. The income is what accumulates when that tiny value is multiplied by millions of people over more than ten years. One video reaches millions with almost no additional production work, the attention it gathers becomes advertising money, and that money concentrates among the top creators. Tetsuya’s home makes the shape of that market visible.
For most of history, a worker’s income was roughly hours worked multiplied by an hourly rate. The internet turned it into what you make multiplied by how many people it reaches. Work society needs and work the market rewards are priced on separate scales. How much of that gap should be left to the market, and where should taxes, social insurance and government-set prices step in? That remains a question for society as a whole, separate from any one YouTuber’s income.
Frequently Asked Questions
Why do top YouTubers earn so much when their work is not essential?
Because markets price reach and scarcity, not necessity. A video reaches millions at almost no extra cost, and according to YouTube Help, creators receive 55% of net ad revenue on long-form videos, while a caregiver can serve only a limited number of people and, in Japan, works within a fee schedule set by the government.
How much do care workers and nursery teachers earn in Japan?
According to Japan’s 2025 Basic Survey on Wage Structure, scheduled monthly earnings averaged 262,900 yen for care workers in facilities and 279,200 yen for nursery teachers, compared with 340,600 yen for all general workers. That is 77% and 82% of the average, excluding overtime and bonuses.
Do most YouTubers make a lot of money?
No. According to Goldman Sachs Research’s April 2023 report, only about 4% of the world’s roughly 50 million creators earn more than $100,000 a year, and Mathias Bรคrtl’s 2018 study in Convergence found that on average about 85% of views went to 3% of channels.
How did Japanese social media react to Tetsuya’s new house?
Reactions on X were mostly admiring and envious, and the most-liked posts praised him for achieving his dreams without flaunting wealth. A post comparing a firefighter’s pay with the mansion was deleted, and replies arguing that money follows audiences spread more widely than the complaint itself.
