I don't have any good sources to back this up, but I thought it was typical for homes in Japan to only have a 30-40 year lifespan anyway. This [0] cites average age of wood-framed homes between 27-30 years, with concrete more like 37 years, and contrasts with US wood frame building lifespan roughly 2x that.

Would enjoy reading comments from someone who really knows about this.

Market value is going to zero by getting 30 years old (probably more earlier), but it not mean that current residents don't live there. They would just live until die. 35yr loan is pretty common so the house must have 35yr life at least.

One of the most important regulation about houses is earthquake resistance standard. "New earthquake resistance standard" was made in 1985 so now is just after 36 year old. So maybe the market is going to change, along with the fact Japanese salary won't up much.
