The recipe traces to a Japanese grocer who grew up in Busan under Japanese colonial rule, was drafted and served in Manchuria during the war, and after repatriating to Hakata adapted the Korean pollock-roe pickle he remembered from childhood into a chili-spiked version built for Japanese tastes — then founded the company that named it.
Salted pollock roe sacs are cured in a chili-and-seasoning marinade until firm and deep red, then sliced open and eaten raw over rice, folded into pasta, or grilled — sold whole by weight from Fukuoka's fish markets and food halls as the city's signature souvenir.
