It's just more silly Japwashing revisionism, like their bullshido crap, pretending that their noble samurai didn't mainly use their magical katanas to murder defenseless people. They did bathe in their smelly hotsprings though, and they're weirdly proud of that for some reason.Why do Japanese pretend nobody but them ever showered, when prior to the Americans and Brits arriving, they very much didn't take showering all that serious.
