Koguma: Okonomiyaki with a signature light texture

Koguma (子ぐま) is a local institution in Yokohama, repeatedly named one of Japan's best okonomiyaki restaurants. Its reputation is built on a signature texture: the batter for its 'Yamaimo Fuwattamayaki' is made with Japanese yam, resulting in an exceptionally light and fluffy pancake that stands out from the denser, more common styles. The experience is made memorable by the long-serving owner (okami), who often finishes the dishes on the hot griddle (teppan) built into your table.

Guests consistently praise the house specials. The Yamaimo Fuwattamayaki (yam okonomiyaki) is a must-try for its 'fuwafuwa' (fluffy) interior. Another favourite is the tsuke-yakisoba, where noodles are served with a seasoned raw egg for dipping. More substantial options like the Gyu-suji Kujo SP, a modern-yaki pancake loaded with beef tendon and Kujo onions, are also popular. Reviewers note the generous portions and high-quality ingredients, often calling the restaurant excellent value for money.

The restaurant's popularity comes with practical challenges. The dining room is compact, and seating is often limited to 90 minutes to accommodate demand. Reservations are difficult to secure, and long waits are common for those without one. A few diners accustomed to the punchier flavours of Osaka-style okonomiyaki found Koguma's version milder, but this is a minority view.

Expect to spend around ¥3,000–¥3,999 for dinner. Reviewers in 2024–2026 reported paying around ¥1,815 for a Gyu-suji Kujo SP Modern-yaki, ¥1,650 for a Gyu-suji Kujo SP Yakisoba, and between ¥1,100 and ¥1,210 for the signature Yamaimo Fuwattamayaki.
