Access is via taxi or car, be ready for that
Honestly, this place doesn’t have good access. It’s not within walking distance of any station, so think of it as taxi or car required. From central Tokyo, the most realistic route is JR Yokohama Line’s Furinkan Station, then a taxi. The surroundings are quiet and rural — a “yes, I made the trip specifically” kind of location — but that trades neatly for the focus you can bring to the meal once you’re there.
Wholesale is the real business; the teishoku is the “side gig”
This shop’s main line is seafood wholesale, with restaurant service positioned as a side operation. The dining room is small, seat count is limited, so there’s both calm and a quiet premium feeling. Sourcing is on industry-level lines, so the fish quality and freshness run on a completely different plane. “Not so much a place to eat as a place to be served fish” — that framing fits.
The mixed fry teishoku is the lead
The flagship mixed fry teishoku. Tuna, whiting, scallop, shrimp, sea bream — a lineup of fish that could each headline at any other restaurant, lined up as fried pieces. The moment it hits the table, you can hear “wait, that’s one portion?” from the neighboring tables. Crisp batter, juicy interior, and each bite forces a quiet “is this really a teishoku?” to escape.
Fugu sashimi as a side — the unreasonable luxury
The biggest shock: fugu sashimi shows up as a supporting dish. The other plates are so stacked that fugu ends up in a side position — a configuration you rarely encounter. Served with grated daikon and ponzu, presented properly. Honestly a first to eat fugu sashimi in “small-plate” fashion.
Daily grilled fish, also a side
Daily grilled fish joins too, also playing support. They grill whatever’s most interesting that day, so each visit rotates. Salt is judged well, umami runs down to the bone, and the rice disappears on nothing but this fish.
Reservations required, and getting harder
Because wholesale is the day job, reservations are required for the teishoku. At the time of visit, November was already fully booked — the place is visibly climbing the staircase toward “hard to book.”
With limited seat count and word-of-mouth quietly spreading, “find it, lock it in” is the right call. As the title hints, I didn’t want to share it, but couldn’t quite keep it to myself.
