Restaurant in Tokyo, Japan
Nine years of awards. Book well ahead.

Sincère has held a Tabelog Bronze Award every year since 2017 and earned three Tabelog French TOKYO Top 100 selections, making it one of Tokyo's most consistent French kitchens. Chef Shinsuke Ishii's dinner menu runs JPY 20,000–29,999 per head across just 18 seats in Sendagaya. Book for a special occasion or take the full room privately for up to 20 guests.
If you have eaten at Sincère once, the question on a return visit is not whether the kitchen has slipped — the Tabelog record answers that plainly. The restaurant has held a Tabelog Bronze Award every year from 2017 through 2026, earned Silver in 2017 and 2019, and has been selected for the Tabelog French TOKYO Top 100 in 2021, 2023, and 2025. At JPY 20,000–29,999 per head at dinner (plus a 10% service charge), this is a restaurant that has compounded its reputation over nearly a decade without drifting. Book it for a special occasion, a milestone dinner, or any evening where the experience has to justify itself. The 18-seat dining room, the sommelier on the floor, and the chef's own approach to service make it a stronger choice for a celebration dinner than a casual weeknight out.
Sincère opened on 12 April 2016 in the basement of the Harajuku Tokyu Apartments in Sendagaya, Shibuya — a neighbourhood that sits between Harajuku's commercial energy and the quieter residential streets approaching Shinjuku Gyoen. Nine years on, the address still reads like a deliberate choice: no street-level signage drama, no tourist foot traffic, a building entrance framed by ivy. The room itself holds 18 seats at table, configured as a sofa-seating space described on the listing as stylish and relaxing, with an open terrace element. For a dinner running JPY 20,000 or more, 18 covers is the right scale , close enough that the kitchen's output lands on the table with intent, not as production-line precision.
Chef Shinsuke Ishii's cooking is French in structure but draws heavily on Japanese produce logic: underutilised fish species, producer relationships, and ingredients chosen for their provenance rather than their familiarity. The kitchen is noted as being particular about fish, and the wine program carries equivalent rigour , the listing flags both wine and sake as specialist focuses, with a sommelier present on the floor. That combination (French technique, Japanese ingredient sourcing, dedicated sake list) positions Sincère in a specific sub-category of Tokyo French dining: not the grand Parisian-mirror rooms of Château Restaurant Joël Robuchon, not the austere tasting-menu precision of L'Effervescence, but something more personal and producer-driven in spirit.
One detail worth noting for anyone planning a second visit: the lunch operation at Sincère has been restructured under the separate name Sincère Plus. The main Sincère room operates dinner only, Tuesday through Saturday, from 18:00 to 20:30, with alternating Mondays closed (1st, 3rd, and 5th of the month). Sundays are closed. That is five reliable dinner services per week across 18 seats , approximately 90 covers maximum per week. For context, this is a tight operation, and the Tabelog score of 4.24 (as of the 2026 award cycle) reflects sustained performance at that scale, not a large-format crowd-pleaser.
The dress code is described as casual formal, with a specific restriction on tank tops, shorts, and beach sandals for men. That framing is permissive by the standards of Tokyo's higher-end French rooms , it signals that Sincère does not require a jacket, but it does expect guests to treat the evening as an occasion. For a celebration dinner, that calibration is appropriate: neither intimidating nor underdressed. The restaurant accepts children aged 12 and over, which narrows the group profile but keeps the room coherent for the kind of evening it is designed to deliver.
The private dining question is worth addressing directly. Sincère has no private room , the listing states private rooms unavailable during evening service. However, the venue is available for private hire for up to 20 people, which means the entire 18-seat room can be taken exclusively. For a group celebration, a corporate dinner, or a milestone birthday where you want the full space, that is a meaningful option: 20 guests, the whole room, a sommelier on the floor, and a kitchen that operates at the same level regardless of whether it is a regular service or a buyout. The alternative in Tokyo's French category , if you need a dedicated private room within a larger restaurant , would be to look at venues like Florilège or ESqUISSE, both of which have different room configurations. But if your group fits within 20 and you want the whole room to yourselves, Sincère's private hire arrangement is worth asking about directly.
For context on the broader Japanese fine dining picture, Sincère sits alongside destination restaurants like HAJIME in Osaka, Gion Sasaki in Kyoto, and akordu in Nara as part of a generation of Japanese restaurants that operate in Western culinary formats but are unmistakably Japanese in sourcing and sensibility. Internationally, the comparison set includes places like Hotel de Ville Crissier and Les Amis in Singapore , French-format restaurants in non-French cities that have built decade-long reputations on consistency rather than hype. Sincère belongs in that conversation. See also our guides to Tokyo restaurants, Tokyo hotels, Tokyo bars, Tokyo wineries, and Tokyo experiences for broader trip planning.
Sincère is reservation-only. There is no walk-in option for the main dinner service. With only 18 seats and a reputation built over nine years of consecutive Tabelog recognition, availability is tighter than the booking difficulty label of Easy might suggest at peak periods , particularly for Friday and Saturday evenings, and for groups requiring the full private hire. Book via phone (+81-3-6804-2006) or through Tabelog. Credit cards are accepted (VISA, Mastercard, JCB, AMEX, Diners). Electronic money and QR code payments are not accepted. Remember to account for the 10% service charge when budgeting.

What to weigh when choosing between Sincère and alternatives.
Sincère can take private buyouts for up to 20 people, which is the only realistic route for a large group given the 18-seat total. Private room hire is not available during standard dinner service (18:00–22:30), so a full buyout is the format to request. check the venue's official channels at 03-6804-2006 to discuss availability.
At JPY 20,000–29,999 per head before the 10% service charge, Sincère sits at the serious end of Tokyo French dining — but the Tabelog record backs it up: consecutive awards every year from 2017 through 2026, plus three selections for Tabelog French Tokyo 100. Chef Shinsuke Ishii's focus on underutilised fish species and Japanese producer relationships gives the menu a point of view you won't find at a generic hotel French. If you want a more internationally familiar grand French format, L'Effervescence charges similarly but reads more classically European.
For French dining at a comparable price point, L'Effervescence in Nishi-Azabu carries Michelin recognition and a more conventional luxury-French presentation. HOMMAGE in Chuo offers a Japanese-inflected French menu at a similar tier. If you want to move away from French entirely, RyuGin delivers the same calibre of chef-driven, product-focused cooking in a Japanese idiom at roughly comparable spend.
No. Sincère operates 18 table seats only — there is no counter or bar seating for the main dinner service. All seats are table format, and the restaurant is reservation-only, so there is no walk-in option regardless of seating preference.
Book at least four to six weeks out as a baseline; peak travel periods (Golden Week, autumn, year-end) warrant two to three months' notice for a restaurant with only 18 seats and a nine-year award track record. Sincère is reservation-only with no walk-in option, and the phone number for reservations is 03-6804-2006. Note that the restaurant closes every other Monday (1st, 3rd, and 5th of the month) and is shut entirely on Sundays.
For the right diner, yes. At JPY 20,000–29,999 for dinner (plus 10% service charge), you are paying for a chef-driven concept with a clear identity — Japanese producer relationships, underutilised fish, and a kitchen that has held Tabelog recognition continuously since 2017. Ranked #215–220 in Opinionated About Dining's Top Restaurants in Japan, it competes credibly at that national level. If your priority is prestige-label French in a grand room, it will not satisfy; if you want a precise, personality-led dinner with a genuine point of view, the price is fair for Tokyo at this tier.
