Restaurant in Tokyo, Japan
Michelin-starred tuna focus, ¥¥¥¥ Aoyama counter.

Sushi Masashi holds a Michelin star and an OAD top-500 ranking, delivering a tuna-focused omakase in Minami-Aoyama that balances creative appetisers with orthodox nigiri technique. At the ¥¥¥¥ tier with a 4.7 Google rating, it is a credible choice for a serious sushi occasion in Tokyo — but booking is hard and requires advance planning through a concierge or reservation platform.
Sushi Masashi holds a Michelin star and a place in Opinionated About Dining's top 500 restaurants in Japan — credentials that, at the ¥¥¥¥ price point, set clear expectations. Chef Masashi Yamaguchi runs a counter that balances creative appetisers with orthodox nigiri technique, with tuna as the centrepiece. If you are planning a serious sushi meal in Minami-Aoyama and want a room with culinary ambition and critical recognition, this is a credible choice. Book well in advance: this is not a walk-in counter.
Sushi Masashi occupies the seventh floor of a building on Kita-Aoyama's gingko-lined stretch — a neighbourhood that already signals a certain register before you arrive. The room sits above the street-level noise, and the view from that height across one of Tokyo's more considered residential and dining quarters gives the meal a sense of remove from the city's pace below. That visual framing matters: this is a counter built for focus.
What you are paying for at the ¥¥¥¥ tier is a structured omakase that moves through two distinct registers. The appetiser course is where Yamaguchi expresses range , tuna sukiyaki is cited as a prime example of his willingness to work outside the conventional pre-nigiri format. These courses are designed to demonstrate originality and set a rhythm before the main event. Then the tone shifts. For the nigiri sequence, Yamaguchi commits to orthodox Edomae technique: no flourishes, no theatre, just precision. The tuna progression , lean, medium fatty, fatty , is the spine of the nigiri sequence, and the vinegared rice is calibrated to the fish's fat content rather than treated as a neutral carrier. That level of tuning is what separates a Michelin-recognised counter from a competent one.
The Google rating of 4.7 across 178 reviews confirms that this calibration lands consistently with guests, not just critics. A high review count at this price point in Tokyo is a meaningful signal: enough diners are returning or recommending the counter to sustain that score without outlier inflation.
The venue database does not include a breakdown of the drinks programme, so specific sake labels, pairings, or cocktail options cannot be confirmed here. What the Michelin and OAD recognition imply, however, is that beverage service at this level is unlikely to be an afterthought. Serious Tokyo sushi counters at the ¥¥¥¥ tier typically offer curated sake selections that complement the rice and fish pairing philosophy , if the rice is tuned to the fish, expect the same logic to extend to what is poured alongside it. Confirm the pairing options directly with the counter when booking, and ask whether a sake pairing can be arranged in advance. At this price tier, arriving without a drinks plan is a missed opportunity.
At the ¥¥¥¥ tier in Tokyo, your sushi options are genuinely strong, and the choice between them depends on what you want from the meal. Harutaka is the counter most serious sushi travellers benchmark against: it is harder to book than Masashi, carries comparable critical weight, and leans more purely into Edomae orthodoxy without the creative appetiser detour. If you want the most technically rigorous nigiri experience in the city, Harutaka is where you should be directing your efforts. Masashi sits a tier below in booking difficulty and offers more range in its opening courses , a better fit if you want a meal that builds through multiple registers rather than committing entirely to nigiri from the first plate. For other high-precision sushi options in Tokyo, Sushi Kanesaka and Sukiyabashi Jiro Roppongiten represent the most established names at this price point, with Jiro carrying a heavier legacy and Kanesaka offering a more accessible booking window.
If you are considering the ¥¥¥¥ tier more broadly and are open to formats beyond sushi, RyuGin gives you a kaiseki experience with comparable critical standing and a more elaborate seasonal structure. For French at the same price tier, L'Effervescence and HOMMAGE are both worth considering if the cuisine format is flexible. Masashi's advantage over these alternatives for a sushi-focused traveller is the combination of Michelin recognition, a tuna-forward programme with clear philosophy, and a counter that is difficult but not impossible to access.
For food and travel explorers extending their Japan trip beyond Tokyo, HAJIME in Osaka, Gion Sasaki in Kyoto, and Goh in Fukuoka are each worth building an itinerary around. For sushi specifically in other Asian cities, Sushi Shikon in Hong Kong and Shoukouwa in Singapore offer the closest regional equivalents to the Edomae counter format.
Yes, with the right expectations. A Michelin-starred omakase counter in Minami-Aoyama, at the ¥¥¥¥ tier, is built for exactly this kind of meal. The structured format , creative appetisers moving into precise nigiri , gives the evening a clear arc, which works well for celebratory dining. It is not a loud or theatrical room, so if the occasion calls for conversation and atmosphere over contemplative focus, manage expectations accordingly. For a culinary milestone anniversary or a serious food-forward celebration, it earns its place.
This is a sushi omakase counter, which means the menu is set and fish is central to the entire experience. The format is not well-suited to guests who cannot eat raw fish, shellfish, or soy-based products. Specific dietary accommodation details are not publicly listed, and neither the phone number nor website is available in current data. If you have restrictions, contact the counter directly before booking , ideally through the concierge or reservation platform you use to secure the seat , to confirm what flexibility exists. Do not assume accommodations without confirmation.
A counter format is one of the better solo dining experiences Tokyo offers at this tier. You are at the bar, facing the chef, watching the meal take shape , there is no awkwardness of an empty opposite seat. Solo diners at ¥¥¥¥ sushi counters in Tokyo are a common enough format that the experience is designed around individual engagement rather than table dynamics. The 4.7 Google rating across 178 reviews suggests the experience translates well regardless of party size. Solo is a legitimate and often preferred way to eat here.
At the ¥¥¥¥ tier, you are paying for Michelin-star recognition, a chef with a documented philosophy around tuna and rice calibration, and a counter ranked in OAD's top 500 restaurants in Japan. That combination justifies the price if omakase sushi is your format and you want a meal with both creative range (the appetiser courses) and technical discipline (the nigiri sequence). If you are newer to omakase and unsure whether the format suits you, a lower-priced introduction elsewhere first would be a smarter sequence. For experienced diners, the value holds.
For a harder-to-book but more purely Edomae-focused counter, Harutaka is the benchmark comparison. Sushi Kanesaka and Sukiyabashi Jiro Roppongiten are the most established names in the same price bracket, with Jiro carrying more historical weight and Kanesaka being somewhat easier to access. For a slightly different sushi style at a comparable standard, Edomae Sushi Hanabusa is worth considering. If you want to broaden beyond sushi entirely, RyuGin offers kaiseki at the same price tier with comparable critical credentials.
Three things matter most before you arrive. First, this is a hard booking: no phone or website is publicly listed, so you will need a concierge, hotel front desk, or a dedicated Japan reservation service to secure a seat. Second, the format is omakase , there is no ordering, and the meal follows a set sequence from appetisers through nigiri. Third, the menu is tuna-forward: if tuna is not your preferred fish, that is worth knowing in advance. The seventh-floor location in Kita-Aoyama means you should confirm the building address before you travel, as the venue is not street-facing at ground level.

|---|---|---|---|---|
| Sushi Masashi | Sushi | In pursuit of new heights, the chef relocated to a new setting, riding the waves of change with his love for the sea, fish, and surfing. His appetisers showcase originality and creativity, with tuna sukiyaki as a prime example. For nigiri, however, he remains committed to orthodox techniques, crafting a menu with a carefully measured rhythm. The spotlight is on tuna, presented in a trio of lean, medium, and fatty cuts. Even the vinegared rice is finely tuned to complement the fish’s rich flavours.; Opinionated About Dining Top Restaurants in Japan Ranked #503 (2025); Michelin 1 Star (2024) | Hard | — |

Comparing your options in Tokyo for this tier.
Yes, with the right expectations. A Michelin-starred omakase counter on the seventh floor of a Kita-Aoyama building is a high-ceremony format by design, which suits milestone dinners well. The tightly structured menu — appetisers with genuine creativity, then orthodox nigiri anchored by a tuna trio — gives a special meal a clear arc. Just confirm your group can commit to the full counter experience; this is not a venue where you order flexibly or linger over your own timeline.
The venue database does not confirm a specific dietary restriction policy. Omakase formats at this price tier generally require advance notice of restrictions, and the menu at Sushi Masashi centres on fish — particularly tuna — making significant dietary departures difficult. check the venue's official channels before booking if you have restrictions; do not assume accommodation is possible.
A strong yes. Counter omakase is one of the few formats that actively rewards solo diners — you get full access to the chef's rhythm and the pacing of the meal without negotiating with a group. Sushi Masashi's structured menu, from inventive appetisers through to the nigiri sequence, plays out best when you can follow it without distraction. Solo booking may also be easier to secure than a table for multiple guests.
At ¥¥¥¥, it is justified if orthodox nigiri technique and a tuna-led menu are what you are after. The Michelin star (2024) and OAD top-500 ranking for Japan (2025) are meaningful validators at this price point, not just marketing. If you want more theatrical innovation across the full meal, Tokyo has other ¥¥¥¥ options; but if precise, classically grounded sushi with creative starters is the goal, the credentials here support the spend.
Harutaka is the closest comparison for purist nigiri at a similar tier. RyuGin sits in the same price bracket but delivers kaiseki rather than sushi, so it suits diners who want a broader multi-course format. L'Effervescence and Florilège are French-influenced fine dining alternatives for those open to moving away from sushi entirely. HOMMAGE is worth considering if a French-Japanese fusion approach appeals. The choice depends on whether sushi technique specifically is the priority.
Book well in advance — a Michelin-starred omakase counter in Kita-Aoyama at the ¥¥¥¥ level does not have walk-in availability. The venue is on the seventh floor at 2-9-9 Kita-Aoyama, Minato City, so build in time to locate it. The menu follows a deliberate rhythm: creative appetisers first, then a nigiri sequence with a clear focus on tuna across lean, medium, and fatty cuts — knowing that structure helps you pace yourself through the meal.
