Pick Your Pig Before You Pick Up the Phone
A converted wooden house in Nishi-Azabu serving two dozen heirloom pork breeds, one cutlet at a time — if you can get someone Japanese-speaking to book it for you.
The cutlet arrives on a rack so the panko stays crisp underneath, a pyramid of cabbage shredded to translucent shaved next to it, and a small bowl of grainy mustard that most of the room will forget to use. The crust is the pale gold of a cutlet fried carefully rather than showily. Cut it, and the fat inside the Matsusaka pork has already started to translate itself into the meat around it, glossy at the edge and still holding its shape.
Butagumi has been doing this from a two-story wooden house on a lane off the main road in Nishiazabu for long enough to land on Tabelog's Top 100 Tonkatsu list in 2021, 2024 and 2026. It sits inside a specialised format Tokyo takes seriously — one dish, a couple dozen regional pork breeds to run it through, and a room built to serve neither more nor less than that.
The cutlet is the best argument for heritage pork you will make in Tokyo, and the reservation is the hardest half of the meal.
Editorial Deep
The curry, ordered on a whim to fill the corner of the table, is the weakest thing that arrives — competent, sweeter than it needs to be, and a distraction from the reason to sit down here. Skip it. The room does one thing seriously and the rest of the menu is scaffolding around the cutlet.
From the main road you will walk past it. The lane is narrow, the sign is small, and the house — a freestanding wooden two-story that has been standing about sixty years — presents as a private residence until you are close enough to read the plate by the door. Step through and the format announces itself: a small entryway, shoes handled the way they are handled in a house, and a staircase to the upstairs room that most first-time bookings end up in.
The staff walk you through the breed list in English, which is the single thing that makes this room work for foreign diners once they are inside it. They will ask what you have eaten before, steer you toward a lighter cut if the table looks hesitant, and time the second cutlet so it lands after the first is finished rather than alongside it. Warm rather than formal, and specific about the pork in a way a reader who cares about the difference will feel immediately.
The signature cutlet from ¥4,400 is the price to defend first. That is one breed-specific cutlet, cooked to the standard the Tabelog 100 list rewards, in a room that seats thirty-eight and refuses walk-ins. Read against what a serious tonkatsu counter charges in Tokyo, it sits comfortably inside the ¥2,000–4,000 lunch band the city has settled on for the format, and it is doing meaningfully more with the pork than the floor of that band delivers.
First visit is Shio Kaze and rice, because the benchmark cutlet is the only way to understand what the rest of the list is being measured against. Second visit is a split table — Matsusaka on one side, Kirishima Kurobuta on the other, ordered together so the intramuscular fat of the first can be tasted against the leaner, cleaner grain of the second, with one bowl of rice between two people and the cabbage refilled twice. That is the meal this room is built to serve, and it is not the meal a first-time booking figures out.
What to eat
Don't miss.
Shio Kaze on a first visit; split Matsusaka and a leaner breed for two
“The best argument in Tokyo for heritage-breed pork, if you can get a Japanese speaker to a phone.”
Go for the breed list and the room's willingness to walk you through it. Skip if what you want is unfussed tonkatsu with no reservation friction — Tonkatsu Maisen in Aoyama does that job for less money and no phone call.
