Each region of Japan has things they consider to be the norm, but what seems like the norm for people of one region may not be the norm to those of other regions. Jin, Yatogame, Tadakusa, and Sasatsu share some of their own "norms."
But Japanese people don't know that. 
They just see it as the norm.
لكن لا يعرف اليابانيّون ذلك، ويرونها عاديّة
Aber die Japaner denken,
das wäre überall Brauch.
Como los japoneses no lo saben,
los consideran algo normal.
Como los japoneses no lo saben,
los consideran algo normal.
Les Japonais l’ignorent et croient
que c’est évident pour tous.
Però i giapponesi non lo sanno. 
Li vedono semplicemente come una cosa normale.
Mas os japoneses não sabem disso,
 e acham que é uma coisa natural.
Но в Японии этого не знают,
для них это в порядке вещей.
