Sincère

About Sincère

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.
