Maybe, maybe not. https://www.japantimes.co.jp/community/2014/03/31/how-tos/japans-30-year-building-shelf-life-is-not-quite-true/ https://www.japantimes.co.jp/community/2014/03/31/how-tos/ja...

  One major thing to consider is that the last major revisions to Japan’s earthquake codes were in 1981, so until the last decade or so, buying a house over 30 years old meant that the house had a significantly higher likelihood of collapsing during a quake.

  What a lot of these articles are missing is the additional building and maintenance costs. Sure a building can be made to last a lot more than 30 years, provided you plan for it upfront with additional materials and architecture costs, and execute regular maintenance including on plumbing and potentially windows/door framing, which also have significant costs. All in all, considering Japan’s building constraints, the total budget for the house lasting 100 years will cost more than a standard house you scrap down and rebuild every 30 years. Basically it’s the ship of Theseus’ paradigm: do you rebuilt a house piece by piece over time, or do full reboots at specific moments. An illustration of this issue when looking at long term ownership of older houses: https://cheaphousesjapan.com/buying-a-house-in-japan-advice/ https://cheaphousesjapan.com/buying-a-house-in-japan-advice/ > So why did I buy a newer house? > I realized that an older, traditional house would be much more work and also more expensive and time consuming to maintain.

Those houses have nothing to do with traditional Japanese construction and joinery, those are just cheap houses built to fill an immediate need. This is a fairly common thing anywhere that is experiencing rapid growth, you either meet the needs of the people or they move somewhere else, you can't expect them to be homeless until their palace is built. Edit: I said traditional and the thread is about modern, but OPs link is referring more to design than construction, very much uses traditional techniques with some variations to adapt it too modern tools. Good article.
