Over on Youtube, and Full 30 CandRsenal have excellent video's on WWI era Carcano's and "Arisaka's".
They have your Carcano, but if it had a monopod and AA sights your Japanese rifle is probably a type 99 .
The videos are on the type 30 , 38 , and 38 and 44 carbines.
All of them seem to be vastly under rated, although the 6.5 cartridges were kind of anemic.
