Vegetarianism and veganism are a pretty foreign concept in contemporary Japan, yet historically, the concept was not foreign at all.
It wasn't until the 50's that beef production and consumption even became commonplace in Japan.
I find myself explaining my beliefs often, so this song is an easy way to clarify my position.

Ore wa saishoku shugisha
doubutsu seihin kuwanai
dobutsu seihin iranei
hentai demo kichigai demo nei

jindo teki na ikikata wo shinjiru
minna jibun katte sugiru
doubustsu wa hito no tame ni iru?
ningen zankokusa o naze kanjinai?

Nihon no rekishi o miro
Kobe beef nanate zutto nei yo
kenko to kankyo o motto kangae yo

daredemo ishi ga areba dekiru
kyoiku o ukete jibun ni kibishiku

watashitachi wa
saishoku shugi sha

watshitachi wa
saishoku shugi sha
