East Sea
Who insisting ’sea of japan’, are ignorant about history, and just grabbers.
The name of ‘north sea’ comes from the continental based concept, just like east sea.
The japanese favorite their nation’s name ‘Nippon’ means ‘the root of sun’. (Ni : sun, pon : root)
The sun’s root is where over the east sea.
If they insist to call the sea by their name,
they should toss away their favorite nation’s name ‘Nippon’,
and call themselves just by ‘japs’.
