Yes, there is interest in SOME old Japanese kits. It seems to be a growing market. I think there were two basic factories in Japan that built all the Japanese drums of that era. One company was the Hoshino factory and...I forget the other one....Yamaha, perhaps? ....but I THINK the Hoshino factory is the one that produced Tama stuff.
As far as value? I have no idea. I think a lot of this particular market depends on the aesthetics -things like the color, the condition of the chrome, everything original and in excellent operating condition. My guess is that older Yamaha drums are probably the most collectible ones right now, but I have also seen old Pearl sets on Ebay go for as much as a vintage Ludwig kit -because of the finish and the condition...over $800.00 for a root beer oyster pearl wrapped finish -never seen another one quite like it. Things like that add value.
If you could post some pictures of the kit here, then that would be immensly helpful in determining a guess as to what they might be worth. Without pictures, it's very difficult.
