Tokyo's Housing Reality: How Small Is Too Small?
Tokyo is one of the most densely populated cities on Earth, with roughly 9.7 million residents packed into the 23 special wards alone. Space is at an absolute premium, and that pressure pushes architects, developers, and landlords to carve up floor plans in ways that would be unthinkable in most Western cities. The result? A category of apartments so compact they border on the absurd.
The Japanese term 狭い (semai, narrow, cramped) perfectly describes what we're looking at here. While Japan has a long cultural tradition of making the most of small spaces, think traditional 和室 (washitsu, Japanese-style room) with its foldable futons and sliding shoji screens, there's a point where clever design ends and impractical design begins. The apartment featured in the viral YouTube video crosses that line decisively.
Units under 10 square metres do exist in Tokyo, though most listings in the 13–20 m² range are already considered extremely compact by international standards. Even so, the Japanese real estate market uses the unit 畳 (tatami, tatami mat) as a traditional measure of room size, one tatami mat equals roughly 1.62 m². Many micro apartments advertise rooms as small as 4.5 tatami, or about 7.3 m², which gives you a sense of how tight things can truly get.
A Closer Look: What Makes This Apartment a Bad Example
The apartment showcased in the YouTube tour is located in central Tokyo, an area where location premiums push rents sky-high while simultaneously compressing available square footage. The layout has drawn significant criticism from viewers, and for good reason.
The Layout Problem
The room's floor plan is the central issue. Rather than using a simple rectangular or L-shaped layout, both of which allow for more intuitive furniture placement, the unit features awkward angular cuts that leave dead zones throughout the space. A bed placed in the main area leaves virtually no room to stand beside it. The kitchen strip is wedged into a corridor-like section that makes cooking and moving simultaneously nearly impossible. There is no dedicated dining area, no separation between sleeping and living zones, and the bathroom is so compact that turning around comfortably is a challenge.
In short, this is not a case of ingenious Japanese minimalism; it is poor spatial planning dressed up in a central postcode.
Criticism of Size and Usability
Viewers commenting on the video were quick to point out that the apartment fails even on its own terms. Several noted that Tokyo does have well-designed micro apartments, properties where every centimetre is intentional, storage is built-in, and the space genuinely functions for daily life. This unit, by contrast, appears to have been subdivided from a larger floor plate with little thought given to how a person would actually live inside it.
The concept of 使いやすさ (tsukaiyasasa, usability, ease of use) is completely absent here. There are no clever storage solutions, no lofted sleeping area to reclaim floor space, and no natural light strategy to make the room feel larger than it is. For the rent being charged, likely somewhere in the ¥60,000–¥90,000 per month range for a central Tokyo address of this size, the value proposition is weak.
Tokyo Housing Culture: Context for Japanese Learners
Understanding why these apartments exist tells you a lot about Tokyo as a city. Land prices in areas like Shinjuku, Shibuya, and Minato have remained among the highest in the world for decades. Developers respond to this by maximising the number of rentable units per building footprint, which inevitably produces units that prioritise quantity of tenants over quality of living space.
For Japanese learners, this is also a useful entry point into real estate vocabulary. When browsing Japanese property listings on sites like SUUMO or Homes.co.jp, you'll encounter terms like 1K (one room plus kitchen), 1R (one room with kitchen integrated), and the infamous ワンルーム (wanrūmu, one-room apartment), the catch-all term for studio-style units that can range from genuinely liveable to genuinely alarming. The apartment in this video would likely be listed as a 1R, with the square meterage buried in small print.
It's worth mentioning that Tokyo's housing situation has sparked ongoing debate, both domestically and among the international expat and digital nomad communities. Subreddits like r/movingtojapan and r/japanlife frequently feature threads where newcomers express shock at what ¥80,000 a month gets you in a desirable Tokyo neighbourhood versus what the same budget delivers in Osaka or Sapporo.
What This Means If You're Planning to Live in Tokyo
If you're a Japan enthusiast seriously considering a move to Tokyo, whether for study, work, or a long-term stay, this video serves as a useful reality check. Not every micro apartment is a disaster. Many are thoughtfully designed and perfectly liveable for a single person with a minimal lifestyle. But the market also contains units like this one, and knowing how to spot the difference before you sign a lease is essential.
Key things to look for: total floor space in square metres (not just tatami count), the actual shape of the room (ask for the floor plan, called 間取り図 (madori-zu, floor plan diagram)), ceiling height, window placement, and whether storage is built in or non-existent. If possible, visit in person before committing; photos are often taken with wide-angle lenses that make spaces look significantly larger than they are.
Tokyo remains one of the most exciting cities in the world to live in, and for many people the trade-off of a tiny apartment for access to its culture, food, transport, and energy is absolutely worth it. But going in with clear eyes, and the vocabulary to navigate the housing market, makes the experience significantly smoother.
