My cherry blossoms are wilting

I mean, growing up in a trailer at one point, it was bigger than your average NY apartment. Certainly more land. We goats and a whole wooded area.

Go eat some more cheeseburgers you greasy mustard tiger.

I was thinking "it cant be that bad"

An article on tokyo apartment sizes and layouts

Relevant part:

Tokyo's micro-apartments are famous worldwide. Some studios are under 20 m² (215 sq ft) – indeed, over 1.4 million households in Tokyo live in homes smaller than 19.7 m² (212 sq ft)! These tiny units often feature a single multi-purpose room, a unit bath (compact modular bathroom), and a small kitchen. In extreme cases, a few tens of thousands of Tokyo residents live in spaces around 10 m² (≈107 sq ft) – essentially a single room without much extra space, measuring about 95 sq ft of usable area. Due to the high population density and limited space in large cities like Tokyo, these compact living solutions have become common, especially for many young people and single professionals.

In any case, <20 m² is the lower end of the distribution. The lower end in my country has to build favella like living places.

Well there’s Johnson Town in Saitama.

We do, but most of them have something within cycling distance that isn't on an 70+ kph road with maniacs (and the closer to civilization, they have public transit).

average Japanese household

Only average because of the heavy population density in the top 5 cities. Most places (by area) in Japan are cheap and spacious. You can have a 2 bed for less than a grand in mid-sized towns.

Mind explaining? I don't speak weeb
