Daisugi, the Japanese technique of growing trees out of other trees (2020)

Isn't this just Pollarding and/or Coppicing, which have been practiced for at least 2000 years in Europe (and probably many other cultures as well), with a healthy dose of orientalism added on top?

The article is pretty light on details. Essentially, the tree is first pruned to create a wide and sturdy base; once that's stable, subsequent shoots from the branches are pruned to grow vertically. The technique relies on this particular variety of cedar which tends to grow vertically but can also be made to spread out a bit. It has some advantages in space-saving and efficiency but it's also very labor-intensive.

I don't quite understand -- what is it about this technique that makes the trees grow perfectly straight and why is

> the lumber produced in this method is 140% as flexible as standard cedar and 200% as dense/strong,

?

Im confused.. wouldnt this be suspect to a weight limit - as the full stem would weigh on the carrying "tree" - especially during wind and storms?

Interesting technique, horrible article. Manages to convey significantly less information than the X thread it mined for ad revenue.
