A six-minute walk up the Ichibangai shopping street from Shimokitazawa Station, Chukasoba Kotetsu is a tiny eight-seat counter that has been selected for the Michelin Guide Tokyo's Bib Gourmand list six times. Its clear soy sauce ramen layers chicken stock with niboshi (dried baby sardines), dried bonito, kombu kelp and shiitake over firm, low-hydration thin noodles. It is a light bowl built to be eaten every day, and it has long been part of the Shimokitazawa shopping street.
About the shop
Owner Tetsuya Oshima spent about a decade training at a Yokohama-style iekei ramen shop — a genre known for its rich pork-and-chicken broth — before opening his own place in Shimokitazawa in 2016. For his own shop he went the opposite way: a light, clear soup built on ingredients alone. Chicken bones are layered with niboshi, dried bonito and kombu kelp, plus shiitake mushroom stock, for a broth that stays light while carrying depth.
The bowl earned a Bib Gourmand in the Michelin Guide Tokyo 2020 edition and has been selected six times in total. You eat it at an eight-seat counter in the Ichibangai shopping street, watching the owner finish each bowl in front of you.
What to order
The baseline order is the shoyu (soy sauce) chuka soba: a soy tare over the triple stock, with firm, thin, low-hydration noodles that carry a wheat aroma. The tokusei (deluxe) version adds house-made chashu pork, wontons and a seasoned egg in one bowl — the easiest way to sample the shop's work in a single order.
Shio (salt) is the second pillar alongside shoyu, and both the wonton ramen and chashu ramen can be ordered in either style. Sides include a plate of six wontons (sara wonton) and chashu rice. In summer the shop runs a cold limited edition; in 2026 it is a chilled (hiyashi) ramen at ¥1,000.
Tips for visiting
Kotetsu uses Japan's meal-ticket system — you buy a ticket for your order when you enter. The shop runs two shifts a day: local media reported 11:30–15:00 and 17:00–22:30 as of June 2026, lunch only on Mondays, closed Tuesdays. It closes early once the soup runs out, so arriving early in the lunch shift is the safest bet.
Temporary closures and limited menus are announced on the official X account (@kote2_shimokita), so check it before you go. With only eight seats you may wait outside at busy times; the shop sits inside a small shopping street, so please queue without blocking the neighboring storefronts.
