Hachimaki are headbands commonly seen throughout Japan (and have been used for a while,even before ww2),as symbols of courage and motivation,and have been used by military and civilans alike.having these as customization items for the japanse,even if its just a simple 日本 (Nihon/Japan) would make the plain customization more alive for them.this shouldnt be shot down from censorship because they would be simple saying,and even if there are any with the full rising run,it is already in the game numerous times in different things.below I have a few examples and a short YT video explaining it better than I did.
