Oh yeah, tons of 'em here. By Kaiyodo, called World Tank Museum. Very nice. Only WWII subjects so far. Too many to list (Tigers, Shermans, T-34s, JS-IIs, Stugs, Pz IIs, IVs, etc.)
Dragon has also jumped on the 1/144 bandwagon with a Tiger I. Tiger II, and Panther G.
These are sold at convenience stores for 250 (WTM) or 350 (Dragon) yen, and come with candy.
Nicely detailed!
They haven't made it over the pond yet??
