Since its opening in 1964, Hotel New Otani has been taking proactive steps in harmonizing its business with the environment. Our "Hybrid Hotel Project" focuses on safety measures such as enhancing seismic capacity of the building, and the reduction of environmental burdens including CO2 emissions, as part of the hospitality we offer to our guests.
Our goal is not only to satisfy our guests, but also to inspire them through our efforts to balance true pleasure and environmental friendliness.

Hotel New Otani Tokyo is the first hotel in Japan to introduce carbon-neutral city gas (CNL) in October 2020, through a partnership with Tokyo Gas Co., Ltd., achieving reduction of CO2 by 35,000 tons over a five-year period. It also participated in the founding of the Carbon Neutral LNG Buyers Alliance, headed by Tokyo Gas.
This unique air-conditioning system was developed in 2003 by NRE Happiness Co., Ltd., a subsidiary of the New Otani group, and is now installed in 554 of the rooms in The Main building and part of the banquet rooms and restaurants. By effectively using the discharged warm air from cooling a certain guestroom to heat another, and vice versa, energy consumption is reduced by 22.7% and CO2 emission by 28%, while providing comfort to each and every guest.
Wide windows offer a superb view while cutting heat and UV rays by 50% and saving air-conditioning energy consumption. Some of the guest rooms have a bath area from where the cityscape can be viewed day and night.
Hot water is supplied by an eco-friendly system that uses heat extracted from the air. Additional efficiency if achieved by utilizing night-time electricity.
We are in the course of replacing all of our lights with LED bulbs. Our largest banquet room Tsuru, and more than 30 other locations within the hotel have already undergone the process, thus reducing CO2 emission by 1,300 tons and power consumption by 3 million kWh annually, compared to conventional lights.
The live kitchen at buffet restaurant VIEW & DINING THE SKY is completely electrified. With less heat emission compared to gas cookers, the air-conditioning load is reduced substantially, resulting in a 14.1% reduction of energy consumption and 29.8% reduction of CO2 emission.
In order to contribute to the promotion of electric cars (EV), a quick charger has been installed in the basement parking lot of The Main building for use by hotel guests. Two vehicles may be charged at once with a maximum output of 120kW, completing an approximate 80% charge in 30 minutes at the soonest.
Having undergone a major renovation, "The Main" building of Hotel New Otani is now robust to withstand an earthquake as massive as the Great Hanshin Earthquake that struck the Kansai area in 1995.
At Hotel New Otani Tokyo, where rich water sources are available in the premises, an advanced treatment plant introduced in 2009 distills drinking water at a maximum rate of 350 tons per day. This water from the fresh-water generator is used as drinking water within some parts of the complex. This well is also designated as Chiyoda ward's emergency-cooperating reservoir and will be used to secure water in times of emergency. The well water plant's ability to distill 350 tons is equal to the amount of water where approximately 9,700 households can use for 3 days.
The hotel is equipped with three large gas turbines that safely and efficiently generate electricity and heat (steam), put to use in times of high demand and also during disasters. The maximum output of 4,500kw is equivalent to 30% of the total electricity used in the hotel.
70mm-thick American Cypress water tanks have been used to produce high-quality water for over four decades. The wood's unique antibacterial quality is effective in purifying the water.
The 500 tons of sewage water from the hotel kitchens are treated in this plant. After removing bits of solid refuse and degrading protein and grease, the water is purified to a level that can be used for certain purposes (greywater). In addition to enabling efficient use of water resources, the plant also contributes to the conservation of rivers and oceans.
Our kitchens produce up to 3 tons of raw refuse every day. All of such refuse is dried and fermented in our Compost Plant, and undergoes further fermentation at an external facility to produce mature fertilizer. The treated fertilizer is used in our Red Rose Garden, and also at the hotel’s contracted farms in Ibaraki and Chiba prefectures that produce rice, potatoes, carrots, onions, ginger, and fruit. The rice breed is named Otani Koshihikari. The hotel purchases the rice and vegetables from these farms to be used in the kitchen of our employee cafeteria, thus completing the recycle chain.
A total of 6,000 square meters of greenery planted on the rooftops of the hotel buildings, including the 2,500-square-meter Red Rose Garden with over 2,000 bushes of approximately 30 breeds, reduces CO2 emission by 38% compared to the standard figure* through photosynthesis. It also protects the building from sunlight and extends its lifespan. Transpiration lowers the air temperature and thus alleviates the urban heat island phenomenon.
*Standard figure for 2023 as announced by the Tokyo Cap-and-Trade Program
Part of the stream that flows from the waterfall to the Benkei Moat outside the hotel is a biotope. Mineral-rich pebbles and multi-purpose bio-soil constitute a well-balanced, pure surrounding, where fireflies are observed during some summers.
These are only a few of the many examples of the "Hybrid Hotel Project" activities of Hotel New Otani Tokyo. The other group hotels, Makuhari and Osaka taking the lead among them, will follow suit promoting the concept and philosophy of;
Eco-Friendly + First Class Luxury Hotel = Enhanced Hospitality Experience
