Hi! I am new to this forum and found this place through google while searching regarding Japanese military swords.
One of my friend was given this Japanese military sword from his uncle that recently passed away.
Based on some basic checking this should be a military sword as there seems to be a number on the blade but what puzzle me is that there is a jade too and a piece of paper hidden in it. Anyway ill upload all the photo that i have and hope that someone recognize what is it. Thanks
