Choshi Seafood: Chiba's Historic Fishing Port Catch

Choshi, at Chiba's easternmost tip where the Tone River meets the Pacific, has long ranked among Japan's top fishing ports by total catch volume, benefiting from the mix of warm and cold ocean currents that converge nearby and bring in a wide range of fish. Sardines (iwashi) and mackerel (saba) are particular signature catches, landed in huge volume and processed locally into everything from fresh sashimi-grade fillets to dried and salted preserved forms.

Dried sardine products, including mirin-boshi (sweet-soy marinated and dried) and tataki-style seasoned fillets, are a common regional food souvenir, valued for keeping well without refrigeration. Fresh catch is sold at local fish markets and served simply, often as sashimi or lightly grilled, letting the fish's freshness carry the dish. Catch volumes and which fish are in season shift throughout the year, so what's actually available can vary quite a bit by visit.
