From Kikkoman to Sempio to Yamasa

I had thought Korean brand Sempio pulled a coup detat on the soy sauce served at Kozo Sushi.  But not so fast.  Kozo has re-affiliated itself with the land of the rising sun by going with Yamasa who has a history with shoyu.

So from my collection of soy sauce packets, Kozo went from Kikkoman to Sempio to Yamasa.
