Hotel New Otani Tokyo can host business events from 8 to 2,500 guests and receptions in 21 halls, within a complex of 1,389 rooms and 33 banquet rooms in Kioicho, Chiyoda. The hotel has run conferences since it opened in 1964, and it handled the Tokyo G7 summits of 1979, 1986 and 1993.
Seminars and company events
The hotel organizes meetings, incentive trips, international conventions and exhibitions, and says its format can scale from 8 to 2,500 guests. Its 33 banquet rooms range from small rooms to large halls, so one program can use several of them at once. A loading dock that takes large trucks adjoins the banquet rooms, which helps for product launches, trade shows and stage builds. A CO2-zero MICE option based on green power certificates is offered for organizers who report on emissions.
Several restaurants list private rooms for business dinners, among them Senbazuru, THE SKY, Trader Vic's Tokyo, Bella Vista, Kato's Dining & Bar, Taikan-en and Tour d'Argent Tokyo. Two banquet rooms, Akebono and Akatsuki, are also bookable as private dining rooms.
Weddings and receptions
The hotel offers 21 reception halls, from rooms for 6 guests to halls for 580. A dedicated wedding section covers ceremonies, receptions, food and cake, and fairs where couples can visit. Tour d'Argent Tokyo also takes wedding parties.
