You would be well advised to have a competent gun smith familiar with Japanese WW II rifles examine it before you try to fire it. Some late war produced Japanese rifles are so poorly made that they are not safe to shoot. Also they used two different calibers in WW II.
As far as the calibers, that was going to be one of my other questions...I'm not actually sure what ammo the thing even uses. One thing I am certain of is that it is not a last ditch rifle...It has the metal butt plate and seems to have a clean, chrome-lined barrel.
Its actually a very interesting weapon...
