Butagumi

Great tonkatsu begins with good pork. Butagumi argues that it does not end there. Since opening in a renovated townhouse in Nishi Azabu in 2003, the restaurant has built its reputation by treating every element of the meal—from the frying oil to the rice and pickles—with the same care as the cutlet itself.

That philosophy reflects the background of its owner. After training at a tonkatsu restaurant and later working in French kitchens, he returned to Japanese pork with a broader understanding of how individual components shape the overall meal. The pork breeds are carefully selected, the frying oil is chosen as deliberately as the meat itself, and every accompaniment has a clear purpose on the plate.

The restaurant's signature, Submarine, uses Himuro buta pork that has been aged for two weeks at sub-zero temperatures. Fried in premium taihaku sesame oil, the coarse panko develops a crisp crust that remains surprisingly light. The thick-cut pork belly stays exceptionally tender, while the fat gradually softens into a clean sweetness as it warms. Many regulars begin with rock salt to appreciate the pork on its own before switching to the house Taiyo sauce, whose gentle acidity and restrained sweetness complement rather than overpower the meat.

The same attention extends to everything surrounding the cutlet. Koshihikari rice from Naka Uonuma is cooked with enough firmness to balance the richness of the pork. Red miso soup carries a subtle note of sansho, smoked iburigakko from Akita adds depth, and finely shredded cabbage dressed with plum provides welcome freshness between bites. Rice, cabbage, miso soup, and pickles can all be refilled, a detail many regulars happily take advantage of.

Another favorite is the katsu curry. Rather than burying the cutlet beneath a heavy sauce, the curry is designed to support it. Slowly cooked onions provide natural sweetness, while a touch of cayenne adds gentle warmth without masking the flavor of the pork.

The dining room is calm and comfortably understated, its rustic interior reflecting the converted townhouse that houses the restaurant. Visitors from overseas are now a familiar sight, yet Butagumi has never felt like a destination created for tourists. More than twenty years after opening, it remains the kind of neighborhood restaurant where many guests order the same favorite meal every visit, confident it will be every bit as satisfying as they remember.
