Get to Minami-Senju Before Ten or Skip the Day
A century-old unagi counter in Arakawa that takes no reservations, no cards, and no shortcuts — the waitlist opens at 10am and the eel is worth the train ride.
The unajuu arrives in a lacquered box that steams when the lid comes off, and the first bite settles the question the morning waitlist asked. The eel is thick, the skin has caramelised where the sauce caught the charcoal, and the flesh gives under a chopstick the way custard would. The sauce is dark and glossy without being sweet — this is the Edo-mae line held cleanly, not the sugar-forward Kansai style that dominates the tourist guides.
Obana has been grilling unagi in Minami-Senju for generations, in a low tatami room in a corner of Arakawa that most visitors never reach. Tabelog folds it into the Unagi 100 for 2026, which in the local scale means it is one of the rooms Tokyo eel obsessives argue about. It takes no reservations and no cards and has structured its entire day around that fact.
The best unagi lunch in Tokyo is a five-hour operation that begins at ten in the morning on a train to Arakawa.
Editorial Deep
The uzaku is the weakest thing on the order — cool slivers of unagi with cucumber in a thin vinegar dressing, more palate reset than dish, and if you were rationing appetite for what follows you could skip it without regret. Start there so the main event lands harder.
Minami-Senju does not look like a place you go for a serious lunch. The walk from the station is four or five minutes through a stretch of Arakawa that reads as residential and slightly industrial, low buildings and quiet streets, none of the signalling that a two-hour queue is about to form. The entrance is modest to the point of anonymous. Shoes come off at the door.
The access model rewards people staying in Tokyo for more than three nights with a morning to spend. It excludes day-trippers, business travellers on a fixed schedule, anyone whose hotel is more than an hour from Minami-Senju, and anyone unwilling to hold a spot on a paper list before ten in the morning for a table at half past eleven.
The unajuu, taken on its own, is priced fairly for what it is. A serious portion of properly grilled Edo-mae unagi over correctly seasoned rice, for a figure that sits well below what the same dish costs at the Ginza and Azabu rooms that have moved onto tasting menus and reservation platforms. The eel is the whole bill and the eel earns it.
The first visit orders the mid-size unajuu, the uzaku as a hedge, and a bowl of eel liver soup because the guidebook mentioned it. The second visit orders the largest unajuu, skips the uzaku entirely, adds the umaki — the eel folded into a dashi-rich omelet — and finishes with the kimosui. That is the meal this room is built for, and it takes a first trip to understand the shape of it.
What to eat
Don't miss.
Unajuu (mid or large size), with the eel liver soup
“The best unagi lunch in Tokyo, if you can spend a morning getting to it.”
Go for the unajuu, for the shitamachi room, and for a version of Edo-mae eel that most visitors never reach. Skip if a two-hour queue on a paper waitlist for a cash-only lunch in Arakawa is not the shape of the day. For a comparable dish with a reservation and a central address, Nodaiwa in Azabu-Juban is the trade.
