Two Japanese Framing Joints
I wasn't sure where this belonged, but here it is.
Impressive, to say the least. Anyone have an idea what kind of wood it is?

Talk about eerie, a guy at work showed me that exact video yesterday.
Amazing joint and the precision is outstanding.
Can't help with the wood.

Wow! I've seen similar stuff before in still pics, but seeing the joints pulled together like that really brings it home. I'd be happy to get such precision with a simpler joint on furniture-sized components, but to get that sort of fit with huge baulks of timber is really impressive!
Imagine being an apprentice - you couldn't afford to screw up too many pieces learning to make those complex joints. I've read somewhere that the temple-builders were the best of the best, so I guess you had to be good to even get a start.
Well, it's a softwood. I vaguely remember an article on Japanese woodwork, I think it might have been in a very early FWW, in which they said they use Fir for that sort of work (which is on the harder side for a softwood). The structural members are not treated with anything, so the article said, but all hand-planed to perfection, which makes them last. Those chunks in the video look pretty finely surfaced, don't they?

A very neat joint indeed.
I think the wood may be some kind of cedar by the look of the grain. That and the fact they could lift it.

I think it's cedar in the first video because of the coloration and the ease with which they move the beams.
Innovations are those useful things that, by dint of chance, manage to survive the stupidity and destructive tendencies inherent in human nature.

Very impressive indeed.
The wood could be Sugi. Also known as Japanese Cedar, although it is not a true cedar.

Possibly, though what about this one?
Japanese cypress (Chamaecyparis obtusa): Perhaps Japan's best-known tree species, Japanese cypress (hinoki) grows in Honshu, Shikoku and Kyushu. The cypress grown in Kiso (Kiso hinoki) is particularly famous. The timber has a beautiful sheen, and a pleasant aroma. It has been used for building temples and shrines since ancient times.

My understanding is that it is common in Japanese joinery for joints to be made so that they need no nails, screws or glue fastening. They are truly amazing joints. That link led me to this as well:

Matthias does a great job of thinking through the geometry in his video.
