I don't know where you can see a lot of japanese woodworkers cutting dovetails, because a lot of their cabinet work tastefully hides them.

A relatively well known series that Kotaro Tanaka showed on youtube had a guy (a "san"?) making a small case that, I'm sure, has a traditional japanese name. Dado and miter dovetail, and he cut the pins with the edge "in the direction of the straws" if that makes sense.

I don't think they have any of this 1:7 or whatever stuff that is obsessed about over here as shinogi are the only chisels I've seen that originally had the very delicate edges. the chisels they call dovetail chisels were probably made to have very short sides by western demand.

I'd guess that more than half of their high end production goes out of country, just like Kamisori. I saw someone in tokyo asked about kamisori on a shaving forum, and he said "they'll be hard to find on the ground here...they mostly sell overseas". That's not a compliment there.
