         | 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.

           | 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:

           | 
           | > I realized that an older, traditional house would be much
           | more work and also more expensive and time consuming to
           | maintain.

           | 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.

       | The bed we recently bought was "mostly Japanese joinery" type
       | construction. It was an absolute joy to assemble, which when I
       | think about it is a very weird thing to say about a bed. But I've
       | told several people this, so it must have had an effect on me.
       | 
       | I don't want to be thought of as shilling for a brand, but the
       | brand I got is Thuma. Assembly instructions:

         | I'm curious how it sleeps and wears over time. I was thinking
         | of building one like that, but decided against it because of
         | the concern of the joints between the legs and the rails: if
         | it's loose enough to assemble in the summer time without an
         | almighty hammer, it seems like it'd be subject to a fair bit of
         | racking and rattling during the winter when the air is much
         | drier.
         | 
         | Does anyone here have any long-term experience with this kind
         | of bed?

         | through construction grade lumber, go to a proper lumber yard
         | that caries higher grades, if they don't have it they will
         | happily get anything you are willing to pay for. And if you
         | want Japanese construction there are plenty of people in the US
         | more than capable of it.

         | If you want stuff that's dimensionally accurate, you'll want to
         | look at the furniture grade selection (which will be a
         | relatively small area) or go to a lumber yard where there's
         | more selection. The big box stores mostly focus on the lower
