They look great! Adding your Japanese to your other Earth forces, you'll be able to do a Martian Boxer rebellion soon!
Funny you should say that Paul ;)
Not sure if you've seen them, but Tsuba Miniatures also do some lovely period Japanese, and some lovely Imperial Russians too!http://tsuba-miniatures.blogspot.com
Check out my game "Run through the jungle" where they make an appearance ;) I got them early on and they are very nice sculpts. :)
Very cool! Somehow I managed to miss that post, looks like a really fun game :-)
