Tabelog ratingAkanezaka Onuma (茜坂大沼) is a small, highly-regarded kaiseki restaurant in Akasaka, where chef Onuma showcases seasonal ingredients, particularly from his native Yamagata prefecture. The experience is centered on a tasting menu served at an intimate 8-seat counter or in a small private room.
Guests consistently praise the technical precision and thoughtful seasoning. Signature dishes include a starter of fuki-no-tou (butterbur sprout) fried tofu, charcoal-grilled fish with crisped scales (urokoyaki), and hand-rolled soba. The meal culminates in a clay-pot rice (donabe gohan), often mixed with seasonal delicacies like sakura-ebi (cherry shrimp), which is a highlight for many. Leftovers are often packed for guests to take home.
While many reviewers, particularly Japanese regulars, are devoted fans, some visitors have reported issues. The most significant concern is unreliable reservation handling, with some non-Japanese guests being turned away despite believing they had a booking. A few diners also noted poor ventilation, leaving clothes smelling of smoke, and found the English communication to be limited.
Dinner courses typically cost between ¥30,000 and ¥39,999 per person, while lunch is in the ¥15,000 to ¥19,999 range, plus a 10% service charge and drinks. Reviewers have recently noted an 11-course kaiseki at ¥27,500 and a lunch tai-chazuke set for ¥1,600. Most find it good value for the quality, but this depends on an appreciation for its subtle, traditional style.
