Hamameshi
A Choshi seafood diner open from 9am. Reminiscent of Toyosu and Tsukiji market-style dining, with generous seafood bowls and sashimi sets as the main draw. Queues form before opening. 30 seats (10 counter, 20 tatami). Closes when ingredients run out.
Reviews often mention 'queue before opening' and 'portions bigger than Toyosu.' TripAdvisor 4.0, 3rd in Choshi. Retty shows 1,358 'visited' logs. Supported by both locals and visitors as a seafood diner open from breakfast.
