I have the Zatoichi figure screamingmetal refered to. It came with a little booklet that had some production notes and other information in it (in Japanese). It think the figure was licensed through Katsu Shintaro's own company, but I'd have to check. If I can locate it I'll look for any refs that might help you and post them here.
Btw, your shinobi line is going great so far. If I can make a suggestion, please make some costumes in historically accurate colors, like the ones I mentioned in my previous post. Those are the colors most often seen here in Japan. Black looks really cool, but is actually easier to see at night than those other colors, all of which blended much better with darkness and shadow than solid black.
Movie and fantasy ninja figures and are great, but they are already being done by others. Historically accurate ninja figures, on the other hand, are still relatively untouched by figure manufacturers... until now. Thanks for filling the need, and please keep up the good work!
