A four-minute walk from JR Otsuka Station's south exit, Sosakumenkobo Nakiryu is a tiny 10-seat counter shop. In the Michelin Guide Tokyo 2017 it became the second ramen restaurant in the world to receive one star (after Japanese Soba Noodles Tsuta), holding it for seven consecutive editions through 2023. Since the 2024 edition it has been listed as a Bib Gourmand for three straight years, and the line of visitors from Japan and abroad has never let up.
What kind of shop it is
Owner-chef Kazumasa Saito graduated from Shinjuku Culinary School, trained at a Chinese restaurant inside a Tokyo hotel, and at 29 joined the ramen shop Chabuya. He went on to serve as head chef at its sister shop MIST in Omotesando and at the Hong Kong MIST that opened in 2010, then returned to Japan and opened Nakiryu in Otsuka in May 2012. That dual grounding in Chinese cuisine and ramen is what the name — 'creative noodle workshop' — refers to.
Michelin awarded the shop one star from the 2017 through 2023 editions, and it has appeared as a Bib Gourmand since 2024. The noodles are made in-house by the chef himself, and the soup is simmered over many hours, according to his official chef profile.
What to order
The signature is the tantanmen (¥1,200 as of July 2026) — a two-layer bowl in which house-made sesame paste and chili oil sit over a hidden soy-based soup. The dashi is drawn from more than ten ingredients including chicken, beef bones, and vegetables, brightened with black and apple vinegar, so the heat lands smooth rather than harsh.
Beyond the signature there is a hotter, numbing mala tantanmen and a hot-and-sour suanlamen, plus a shoyu ramen built on house-made dashi-infused soy sauce blended with dark soy from Wakayama, a shio ramen, and tantan or shoyu tsukemen (dipping noodles) — the clear-soup side of the menu is wide. Toppings such as shrimp wontons and seasoned egg round out the lineup.
Tips for visiting
Since February 2024 entry has been managed with numbered tickets, announced on the shop's official X account: from 8:00 a.m., a tablet at the storefront issues tickets, with reports describing 30-minute time slots and groups of up to 8. The system can change, so check the official X or Instagram before you go.
Mondays are lunch-only and Tuesdays are closed, and the shop shuts once the soup runs out — on a day you absolutely want the bowl, secure a ticket early. There are only 10 counter seats and no parking. For payment methods and other details, the official SNS is the place to confirm.
