Maguro Mart: A Tuna Specialist in Nakano That Takes the Fish Seriously — and Has Fun Doing It

Maguro Mart: A Tuna Specialist in Nakano That Takes the Fish Seriously — and Has Fun Doing It

Most restaurants that specialise in a single ingredient do so by narrowing their focus: one product, treated simply, presented without distraction. Maguro Mart takes the opposite approach. Tuna is the subject, but the kitchen’s ambition is to show how much range that subject actually contains — through cuts, preparations, and combinations that most tuna restaurants wouldn’t attempt.

The space matches the energy. A renovated warehouse south of Nakano Station, with exposed concrete walls and warm lighting — industrial in structure, lively in atmosphere. It’s a room that fills up and stays full, which tells you something about the place before the food arrives.

The Nakochi: The Dish That Defines the Visit

The honmaguro nakochi is the piece of theatre the restaurant is known for. A large tuna spine arrives at the table, still bearing the dark red meat that clings to the bone — and the method of eating is to scrape it off yourself, using a spoon, directly at the table.

It’s a format that generates conversation, which seems intentional. The meat itself is fine-grained and intensely flavoured, dissolving cleanly once it’s in the mouth. The experience of obtaining it — scraping a tuna spine at a table in Nakano — is unlikely to resemble anything else you’ve done recently, which is part of the point.

The Maguro Mart mori — a platter of rare cuts — is the other essential order. Alongside the expected akami (lean) and toro (fatty belly), the platter includes cuts that rarely appear outside specialist restaurants: noten (the forehead meat), ago (jaw), and nodo (throat). Each has a different texture and fat distribution. Eaten in sequence, the platter works as an education in how varied a single fish can be.

Beyond Sashimi

The menu extends well past raw preparations. The nama-uni-sho — fresh tuna topped with sea urchin — is the kind of combination that justifies its own existence without requiring explanation. The maguro rare tempura takes lean tuna, applies precise heat, and produces something that sits between sashimi and fried food in a way that works better than it has any right to. The nodobura-niku steak — thick throat meat, grilled — rewards the people who order it.

The sake list is considered. Dry styles that keep pace with the fish; richer options that hold up against the fattier cuts. The staff are willing to guide the pairing if asked.

Practical Notes

Maguro Mart is a reservation restaurant. It fills up, and showing up without a booking is unlikely to work, particularly on weekends. Planning ahead is necessary, but the restaurant is worth planning for.
