Very odd... it seems that although Hikari operates in both the US and Japan, the products it sells in each are completely different. Here in japan it's all under the name "kyorin" even though the packaging still says Hikari, and these seem to be the only frozen foods they sell.There is a variety of packaging but here's a sample.

I swear, why do these things have to be So Difficult hahaha. I love living in Japan but starting this hobby is really making me bemoan the fact that I'm not back in the US lol
