Can you identify this bayonet?

Not sure if my dad or father in law brought this home from WWII, but believe one of them did as I didn’t buy it. Dad was in the Pacific against the Japs and father-in-law Europe against the Germans. Any info is appreciated.

It's an Arisaka type 30. I have a couple of them.
