I know I shouldn't be, but I'm always surprised when I learn what Japanese names (place names, names of people, or band names) actually mean.
I've listened to ZAZEN BOYS for years and never questioned what ZAZEN meant. But today I came across 座禅 (the kanji for sit/seat and zen), meaning seated zen meditation 🧘♂️.
Of course, ZAZEN BOYS' music is extremely unsuitable for zen meditation 😂
