I'm looking to purchase a Japanese rising sun flag. I want to get some opinions regarding authenticity before possibly purchasing. As you can see from the pictures posted, it's not in the greatest condition, however, for the age of it, it's not bad. The seller is from Japan. The flags measures roughly 27 x 39 inches. It is made of silk. It shows some staining and discoloration which looks like normal wear and tear. The corner tabs appear to look right as well. If anyone could give me some more information regarding Japanese flags and what to look for to make sure they are authentic, I would greatly appreciate it. I welcome all opinions! Thanks for your time.
