Sorry your question isn't getting any responses. I saw the original post but had nothing to offer. I think this topic requires two pretty specific sets of knowledge, and although I think there are folks here who know a fair bit about European tree species, but I think relative to most of the building techniques considered here Japanese woodworking is a "high art" - revered but not practiced.
I hope you can find a community or other source of appropriate knowledge. And please, share back! You never know what might happen to the seed you plant!
Same here, i saw it, thought hope someone will know...
People are very busy.
What is the wood Japanes use? And what kind of properties does that have?
That's where i would start personally.
Creating edible biodiversity and embracing everlasting abundance.
When i did some reading up on beam and pole building for my own project , some of it was about the japanese methods and timber used ---but way beyond my skill --so i used rough sawn timbers and logs for framework but the tree species for timber is very restricted around my part of the world--and quality stuff is very expensive--so most of what i used was sitka spruce --very coarse and with the odd red pine and larch log---all rough and ready stuff . The japanese sites mentioned working with their local types of red pine ,black pine ,cedar and cypress ---all fine grained and high quality.
