Butagumi

Butagumi is tucked into a quiet side street in Nishi Azabu, inside a renovated old townhouse that suits the restaurant’s style well. Since opening in 2003, it has become a destination for diners who take tonkatsu seriously. The owner first trained in a tonkatsu shop, later worked in French cuisine, and brought that combination of discipline and precision back to a single subject: how to make a better pork cutlet.

That attention shows in every part of the meal. Pork breeds are selected carefully, frying oil is chosen for flavor and texture, and the supporting items receive the same level of care as the main plate.

The signature dish, Submarine, uses Himuro buta pork aged for two weeks at sub zero temperature. The crust is coarse and crisp without feeling heavy. It is fried in premium taihaku sesame oil, which leaves a cleaner finish than many richer oils. The thick cut pork belly stays remarkably tender, while the fat turns sweet and soft as it warms. Rock salt brings out the depth of the meat, while the house Taiyo sauce adds gentle acidity and sweetness for a different direction.

Rice is Koshihikari from Naka Uonuma, served with enough firmness to stand beside the richness of the pork. The red miso soup carries a light note of sansho. Pickles include smoky iburigakko from Akita. Shredded cabbage with plum dressing gives the meal needed freshness. Even better, these sides are refillable, which regular guests know to take advantage of.

Another strong order is the katsu curry. The sauce is thinner than the heavy gravies found elsewhere, with sweetness from slowly cooked onions and a mild lift from cayenne pepper. It sits somewhere between classic Japanese curry and a lighter spice driven sauce, adding flavor without covering the cutlet itself.

The room is calm and softly lit, with a balance of rustic warmth and polished comfort. International visitors are common, but the restaurant never feels built around tourism. It still feels like a place people return to because the food holds up.
