Overall, decent condition. 
 
This bayonet has a very interesting piece of "trench art" on the grip. It appears to be a 5-leaf cherry blossom that was used on Japanese-issued equipment (such as the type-19 kyu gunto sword). 
 
From the research I did, it does look like Germany sent a number of captured VZ-24 rifles to Japan during the war, and the Japanese issued them to the IJN.
I'm by no means an expert in this very niche topic, so I leave it to the buyer's discretion.
 
If you have more information that could help, please message me!
 
 
There is cosmoline and dirt present throughout. 
 
Tip of the scabbard is also broken.
