Restaurant in Tokyo, Japan
Tokyo's most credentialed French room, priced accordingly.
L'OSIER is Tokyo's most credentialed French grand maison: three Michelin stars (2025), 98 La Liste points, and over five decades of operation in Ginza. Dinner runs JPY 50,000–59,999 per head before wine and service; lunch offers the same kitchen at roughly half the price. Reservation-only and near-impossible to book — plan weeks or months ahead.
If you are comparing L'OSIER against Tokyo's newer wave of French restaurants, [L'Effervescence](https://www.joinpearl.co/restaurants/leffervescence-tokyo-restaurant) and [Florilège](https://www.joinpearl.co/restaurants/florilege) offer more contemporary, produce-driven cooking at a lower price point and with meaningfully easier reservations. L'OSIER plays a different game entirely. This is Ginza's grand maison format: formal, ingredient-obsessed, and operating at a price and ceremony level that most Tokyo French restaurants do not attempt. Three Michelin stars (2025), 98 points from La Liste in both 2025 and 2026, Tabelog Silver in 2025 and 2026 (Gold in 2021 and 2022), and consistent selection for Tabelog's French Tokyo 100 list since 2021. The credentials are not decorative. They reflect a restaurant that has maintained the highest tier of French dining in Tokyo for over five decades.
L'OSIER sits in Ginza's core, a seven-minute walk from Ginza Station on the Tokyo Metro and six minutes from the Ginza exit of JR Shimbashi Station. The building is owned by Shiseido, giving the space a considered, gallery-like quality — the willow-tree glass artwork at the entrance references Ginza's history directly. The name itself translates as 'The Willow', tied to the trees that once defined the neighbourhood. None of this is incidental: the atmosphere at L'OSIER is formal in the way that genuine grand maisons are formal, not in the way that hotel restaurants imitate formality. The room seats 34 across main dining and private configurations, and the energy is correspondingly quiet and measured. If you are expecting the animated hum you find at [Sézanne](https://www.joinpearl.co/restaurants/szanne-tokyo-restaurant) or [ESqUISSE](https://www.joinpearl.co/restaurants/esquisse-tokyo-restaurant), recalibrate. L'OSIER's ambient register is closer to a concert hall between movements: attentive, still, charged.
Chef Olivier Chaignon leads the kitchen with a documented focus on producer relationships across Japan, channelling French technique through Japanese ingredient sourcing. The menu emphasises fish, and the wine program is handled by a sommelier. English menus and English-speaking staff are available, which matters at this price point for international guests. A 15% service charge applies on leading of menu prices, and male guests are required to wear a jacket. Shorts and sandals are explicitly prohibited. These are not suggestions.
The editorial angle here matters for your booking decision. L'OSIER's 34-seat main room does not offer a chef's counter in the traditional sense, so if your primary goal is watching the kitchen work up close, the counter format you find at Tokyo sushi venues or at places like [Château Restaurant Joël Robuchon](https://www.joinpearl.co/restaurants/chteau-restaurant-jol-robuchon-tokyo-restaurant) is not what L'OSIER delivers. What it does offer is private room access that changes the experience significantly. Private rooms accommodate two to ten people. For groups of seven to ten, the room charge is ¥11,000 at lunch and ¥22,000 at dinner. For smaller groups of two to four, the private room rate is ¥55,000 for either meal period. That premium is substantial, but it converts a formal dining room dinner into something closer to a fully exclusive experience with dedicated service. For a significant occasion with two to four people, the private room option is worth considering seriously; the cost per head becomes almost secondary at that point.
L'OSIER is open Tuesday through Saturday only, closed Sunday and Monday, with additional closures for public holidays, mid-August, and the year-end and New Year period. Lunch runs from 11:30 to 15:00 with a last order at 12:30; dinner from 17:30 to 22:00 with a last order at 19:00. These are tight service windows. Lunch is the practical entry point: at JPY 20,000 to JPY 29,999 per head (based on Tabelog pricing data), it represents roughly half the dinner cost of JPY 50,000 to JPY 59,999. Review-based spending at dinner trends toward JPY 100,000 per person once wine and service charges are factored in. Lunch lets you assess whether L'OSIER's particular form of French grand maison service is the right format for you before committing to a full dinner spend. Come on a weekday rather than Saturday if your schedule allows , Saturday lunch is the most competitive reservation of the week and the room will be at its fullest, which works against the quiet register that makes L'OSIER distinctive.
L'OSIER is reservation-only. Phone reservations are taken at 03-3571-6050 (or the toll-free line 0120-156-051) between 10:00 AM and 8:00 PM on business days. There is no online booking portal listed in the venue data. Given the three-Michelin-star status and the 34-seat main room, treat this as a near-impossible booking , plan well ahead, particularly for dinner and for Saturdays. If you are visiting Tokyo and this is a priority, build the reservation process into your trip planning before you book flights. The restaurant requests parking notification at the time of reservation; ten spaces are available. Wheelchair access is confirmed. Cards accepted include Visa, Mastercard, JCB, Amex, Diners, and UnionPay, as well as QR payment systems including PayPay and Alipay.
Book L'OSIER if you want Tokyo's most credentialed French grand maison experience and the formal, hushed room is part of what you are paying for. It is the right choice for significant occasions , anniversaries, corporate entertainment, or any dinner where the setting needs to carry as much weight as the food. It is also the right choice if you have already worked through Tokyo's more contemporary French options ([L'Effervescence](https://www.joinpearl.co/restaurants/leffervescence-tokyo-restaurant), [Florilège](https://www.joinpearl.co/restaurants/florilege), [ESqUISSE](https://www.joinpearl.co/restaurants/esquisse-tokyo-restaurant)) and want to experience what a half-century-old institution committed to constant innovation actually looks and feels like.

Come prepared for a formal, multi-hour French grand maison format with dinner running ¥50,000–¥59,999 per person before the 15% service charge. L'OSIER is reservation-only — call 03-3571-6050 between 10:00 AM and 8:00 PM on business days — and the room seats just 34, so availability is tight. Lunch (¥20,000–¥29,999) is the lower-risk first visit: same Michelin 3-star kitchen, lower spend, and a clearer read on whether the formal format works for you before committing to a dinner outlay.
It works for solo diners, but L'OSIER's 34-seat room is set up for couples and groups rather than counter-style solo eating, so you won't get the chef interaction that makes solo visits at places like Harutaka worth the premium. A solo lunch booking is the sensible call: the price is more contained at ¥20,000–¥29,999, and the English-speaking staff and multilingual menu remove most of the friction. Solo dinner at ¥50,000–¥59,999 before service charge is harder to justify unless you specifically want the full formal experience.
A jacket is required for male guests — the venue is explicit on this. Shorts and sandals are not permitted for anyone. This is a Michelin 3-star room in Ginza, so smart dress for all guests is the working assumption; business formal or cocktail attire fits the room and avoids any awkwardness at the door.
For French at a lower price point with more creative energy, L'Effervescence in Nishi-Azabu is the natural comparison. HOMMAGE offers French technique with a tighter, more intimate format. If you want the grand maison scale but are open to Japanese cuisine, RyuGin carries comparable prestige at a similar spend. Crony is a sharper choice if you want a less ceremonial room. L'OSIER's specific case is the combination of Michelin 3-star credentialing, Tabelog Silver, La Liste 98pts, and the Ginza heritage address — no direct substitute covers all of that simultaneously.
Lunch is the better entry point for most diners: ¥20,000–¥29,999 versus ¥50,000–¥59,999 at dinner, same kitchen and same Michelin 3-star standard. Dinner makes sense if the full extended format is what you are after — service runs to parties over 2.5 hours — or if the occasion warrants the higher spend. Note that last orders at lunch are 12:30 PM, so an 11:30 AM booking gives you the most time.
Yes, with the right group. Private rooms accommodate 2–10 people, with room charges of ¥55,000 for parties of 2–4 and ¥11,000/¥22,000 (lunch/dinner) for groups of 7–10. The kitchen handles birthday plates, a sommelier is on hand, and English-speaking staff are available — which removes the logistical stress for international guests. For a large private event, the venue can be booked exclusively for up to 44 people. Call ahead specifically to discuss private room availability, as it is not bookable through the standard reservation line.
Keep this venue in your Pearl passport, rate it after you visit, and track it alongside every other place you collect.
