Oh and I forgot to mention that in the 1/76 scale Milicast does some Japanese tanks too, but they're resin which is not everyone's favourite.
Their battlefield series includes easy to assemble kits. Some of the details are rather delicate for gaminng purposes (gun barrels in small calibre guns), but they're lovely, great detail, and you only need to glue guns & accessories, normally the tank itse self is just two pieces, turret & one piece body with tracks and all.
