Need help identifying this flag

[mcurrie17]

I found this flag on a website. It states that it is a WW2 JAPANESE MEDICAL FACILITY FLAG FROM THE PACIFIC ISLAND CAMPAIGN 1942-1945. I am just looking for some information to verify if it is authentic or not or if it is what it's stated to be.

The flag is shown upside-down. It is the Osaka city emblem.

Best to zip off a note to the seller.
