Don’t mention the war!
Definitely not. 😆
Don't be like that idiot Youtuber "Johnny Somali" who has been running around Japan being a jerk. Among other things, he harasses passengers on trains saying, "Hiroshima, Nagasaki, we'll do it again," goes into restaurants playing loud music from his smartphone, and knocks groceries off of shelves in markets.
The ultra-polite Japanese finally had enough of him and have decided to go full Kempeitai. He is now in jail and facing charges in a country where accused criminals face a 99% conviction rate.
