Bro, get the fuck over this stupid rice bullshit; it's a great food, and if I had to eat only one food it would be rice, and whatever... but it's not inherently Japanese, nor will a Japanese person lose their mind without it. (Hell, it's not even very efficient; gimme Wheat, or even Rye, any day of the week...)
Rice is great, but it's been cultivated and eaten in both China and India for longer than humans have lived in Japan; get the fuck over this inaccurate and ridiculous fucking trope!
Also, baths didn't even exist in Japan until long after the rest of Eurasia and Africa had popularized them; quit pretending that these things are inherently Japanese when they've existed longer than your nation... yeeesh...🙄
