Nanpudomari Market opened in 1974 as a production-area market centered on fuku. Around it, a seafood-processing district concentrated the work of handling and preparing the fish. The Shimonoseki Fuku Federation has its office inside Nanpudomari Market, and its member list includes markets, wholesalers, processors, hotels, and fishery organizations with addresses across Shimonoseki. In this setting, fuku means early market work, removal of unsafe parts, sorting by quality and specification, and shipments matched to different uses through the year.
