Sumibi Yakiniku Horumon Sawaishi (炭火焼肉ホルモンさわいし) has earned a cult following among meat lovers for two things: colossal, expertly trimmed cuts of harami and sagari (skirt steak), and some of the cleanest-tasting horumon (offal) available in Japan. Located in Shinjo, a residential district in Kawasaki, it's a destination that requires significant advance planning but rewards diners with an unforgettable charcoal-grilled feast.
Guests consistently praise the steak-like slices of harami and sagari, often describing them as life-changing for their buttery texture and intense beefy flavour. The thick-cut tongue and a wide variety of pristine offal—including liver, shimachō (large intestine), and senmai (omasum) sashimi—are also highlights. Everything is cut to order and grilled by diners over high-grade binchotan charcoal. The typical omakase (chef's choice) menu flows from sashimi to salted meats, then marinated meats, a selection of horumon, and a satisfying finisher. Popular closing dishes include a rich black-tongue curry and refreshing cold noodles.
The main drawback is accessibility. Reservations are notoriously difficult to secure, with waits often stretching from several months to a year. Some premium cuts can also sell out, particularly on weekends. While service is generally efficient, a few reviewers have noted occasional slow delivery or terse interactions during peak hours. With a typical dinner spend of ¥20,000–¥25,000 per person, it is a premium experience. Reviewers recently paid around ¥18,000 for the omakase course, with special harami cuts costing ¥3,600–¥5,000 and the black-tongue curry priced at ¥1,200–¥1,800. Despite the high price, diners overwhelmingly consider it excellent value for the sheer quality and generous portions.

- Getting There: A 5-minute walk from Musashi-Shinjo Station.
- Payment: Credit cards (VISA, Master, JCB, AMEX, Diners) are accepted. Electronic money and QR code payments are not. The bill must be paid for the entire table at once; individual payments are not allowed. A 10% service charge applies.
- Rules: No children are allowed. Guests are asked to refrain from wearing strong fragrances like perfume. Photography is limited to the food only.
- Seating: The restaurant has 26 seats, including counter seating and small tables.
- Language: Menus have limited English, but staff have a basic command of the language. Ordering the omakase course is the simplest option for non-Japanese speakers.
