Kioicho Mitani

Who Should Book Kioicho Mitani

Kioicho Mitani is the right call for serious sushi enthusiasts who want a decorated counter experience in central Tokyo without the full theatre of a three-Michelin-star room. If you are visiting Tokyo specifically to eat well, have JPY 40,000–60,000 per person available, and want a venue that has earned recognition from Tabelog every year since 2018, this belongs near the leading of your shortlist. It is also one of the more practical options for groups: a private counter room for up to six makes it workable for a business dinner or a small celebration in a way that many comparable sushi counters simply are not.

The Venue

Kioicho Mitani opened in July 2016 inside Kioi Terrace, a modern mixed-use complex in Chiyoda's Kioicho neighbourhood, and it has held a Tabelog Bronze Award every year from 2018 through 2026 — nine consecutive years of recognition on Japan's most data-rich restaurant platform. Its Tabelog score sits at 3.95–3.96, and it has appeared on the Tabelog Sushi TOKYO Top 100 list in 2021, 2022, and 2025. Opinionated About Dining ranked it among Japan's leading restaurants in 2023, 2024, and 2025, placing it at #275 in 2024 and climbing to #243 in 2025. That is a meaningful trajectory, not a plateau.

The room seats 19 in total: a 13-seat main counter and a private counter room for six. The format is reservation-only omakase under chef Hiroyuki Takano, with the kitchen noted on Tabelog as being particular about its fish sourcing. Lunch runs JPY 40,000–49,999 per person; dinner runs JPY 50,000–59,999. Review-based averages suggest some guests spend in the JPY 30,000–49,000 range at lunch, which likely reflects variation in drink spend rather than menu pricing.

The setting inside Kioi Terrace gives the experience a polished but unpretentious quality. Smart casual dress is expected, the room is entirely non-smoking, and the drinks list covers sake, shochu, and wine, with the team described as particularly attentive to both sake and wine selection. That drink programme matters at this price point: at JPY 50,000+ per head, you are paying for the full counter experience, and the beverage pairing is part of the value calculation.

Getting there is direct. Nagatacho Station (Tokyo Metro) has a direct connection to Kioi Terrace via Exit 9a, roughly 212 metres from the station. Parking is available on-site for those arriving by car. Closed days follow the Kioi Terrace schedule rather than a fixed weekly pattern, so confirm before visiting.

For families or groups travelling with children, private rooms accommodate strollers and welcome children, which is a rarity at this price tier in Tokyo sushi. That flexibility is genuinely useful if you are planning around a mixed-age group.

Compared to the broader Tokyo sushi tier it occupies, Kioicho Mitani delivers consistent, peer-validated quality in a space that is more relaxed than its award record might suggest. The counter is intimate without being austere, and the Kioi Terrace address gives it a corporate-district accessibility that suits both business diners and food-focused travellers staying in the Akasaka or Nagatacho corridor. For explorers building a Japan itinerary around serious eating, it sits logically alongside Harutaka, Sushi Kanesaka, and Edomae Sushi Hanabusa as part of a considered Tokyo sushi programme.

Booking Kioicho Mitani

Reservations are required and can be made by phone (+81-3-6256-9566) or through Pocket Concierge online. Booking difficulty is rated easy relative to the top tier of Tokyo sushi — meaning you are unlikely to need months of lead time, but you should still plan ahead, particularly for weekend evenings. The private room (up to six people) and full private hire (up to 20) make this one of the more group-accessible options in its category.
