About this ingredient
Adult Japanese pilchard (Sardinops melanostictus) — the foundation of niboshi (existing), shirasu (juvenile), and the premium adult retail market. Hokkaido, Aomori, Chiba, and Shimane lead commercial harvest; specialty processing in Kanagawa and Wakayama produces salt-cured (shio-iwashi), kabayaki (grilled-eel-style), and dried products. Functional positioning targets DHA / EPA / vitamin-D content. Distinct from existing katsuobushi / niboshi / saba-bushi entries.
