WWII Japanese American Soldier in Japan - Unknown Patch

[bunkerhillburning]

With some luck a forum member or two might be able to chime in with some information on this photo.

 

Purchased from a seller who had a large number of US Army in Japan during the occupation. This photo caught my attention as I collect Japanese American photographs / documents and this includes photos of such Americans serving during WWII.

 

Can anyone identify the patch seen on the Japanese American's uniform?  I can not make it out.  

 

Of course, the back of the photo is not captioned.
