Tabelog ratingKiyo Ishouten (清井商店) has quickly become a standout in Tokyo's competitive ramen and soba scene by focusing on a refined, contemporary version of Okinawa soba. The restaurant's signature is its soki (braised pork ribs), which are slow-cooked until collagen-rich and tender enough to fall apart with chopsticks, then lightly charred for extra flavour. These are served in a clear but deeply savoury broth made from katsuobushi and animal stock, creating a clean yet umami-rich base.
Guests consistently praise the quality of the soki, often served in generous portions of three large pieces. The signature Kiyo Soba, which includes all toppings, is particularly popular for its layered flavours, combining the rich pork with grilled tomato for acidity and aosa seaweed for a touch of oceanic brightness. The free mini jūshii (Okinawan seasoned rice) at lunchtime is another highlight, as is the quick service and the table-side condiments like kōrēgūsu (chilli-infused awamori) for customising the heat. The relaxed atmosphere is complemented by an Okinawan soundtrack and self-service sanpincha (jasmine tea).
The main drawback is the restaurant's popularity, which often leads to queues, especially at lunchtime. A few diners noted that the seasoning is slightly sweeter and the noodle texture different from what you might find in Okinawa, which may not suit purists. Reviewers in 2024–2026 typically spent between ¥1,000 and ¥1,999. A bowl of the all-topping Kiyo Soba cost around ¥1,350, while the standard Soki Soba was about ¥1,000. Most agree it offers excellent value, given the high quality and generous portions of the pork ribs.
