Looks to me like a bayonet.

Can post measurements in a bit if needed for better I.D.

Japanese ww2 vintage. I have one like that but from the Mukden arsenal.

It's a Japanese Type 30.

Go to the website worldbayonets.com and weave your way through the menu to Japanese bayonets, and compare.

Pretty sure that's it.
