It's a tag for the 9th Mountain Artillery Regiment's Replacement Unit

Starting with right side column

Mountain Artillery 9 (補 = 補充) Replacement
番2126 is the soldier's personal number

I have no idea either but without more knowledgable guidance I would keep in mind it may have been repurposed for luggage, etc.

Cheers!
