If Niigata is the birthplace, Hiroshima is the second capital. English market surveys consistently list Hiroshima breeders among the top tier, and the region's two best-documented houses show its range: Sakai of Mihara, founded in 1890 and famed for Kohaku and Sanke, and Omosako of Kure, founded in 1960 and synonymous with Shiro Utsuri.
Hiroshima fish regularly reach the top of national shows, and the region was among those whose six Niigata–Fukuoka–Hiroshima farms regained China-export qualification when that trade reopened in October 2024, according to MAFF-based reporting.
This page names long-established breeders only as historical facts with founding dates. It is not a breeder database: no stock, prices, rankings or promotional text appear here.
