Sanriku Rias Tei
A famous stand-and-eat soba and bento shop inside Sanriku Railway's Kuji Station. The 'Uni Bento' (sea urchin lunchbox), a treasure of Northern Sanriku, is limited to 20 per day and draws early morning queues. Simple yet spectacular: steamed uni piled on top of uni-seasoned rice. The soba using local specialty 'Mamebujiru' soup is also famous. Open from 7am, a local breakfast staple.
Reviews say 'Must eat when in Kuji', 'The Uni Bento is in a league of its own - unbelievable fresh sea urchin at this price', 'Worth lining up from morning', 'TripAdvisor #1 in Kuji.' Tabelog 3.46/248 reviews. March 2025 blog post also describes the moving experience of fresh uni piled high.
