Artworks created by people with disability are displayed and sold at our hotels to provide the public with easy access to art and promote the spirit of inclusion. This community-based initiative is driven by collaboration with local facilities for people with disability in the communities where the exhibits are held.

Winner of the 7th Japan Tourism Award

The ParaArt traveling exhibition "HAPPY SMILE ART" won an award at the 7th Japan Tourism Awards. This award recognizes the sustainable and outstanding efforts of both domestic and international organizations, companies, groups, and individuals who have contributed to the development of the expansion of tourism.

Initiatives to reduce food loss

photo

We are working towards the reduction of food loss by measuring the level of food waste and striving to provide the appropriate amount of food.

We proudly participate in the Ministry of Agriculture, Forestry and Fisheries' food loss reduction national movement (NO-FOOD LOSS PROJECT) and ask customers for their cooperation in displaying a “POP” of ceramic plates in all of our buffet restaurants.

We have introduced the food-sharing service "TABETE," a service in which leftover food from the buffet is used to work towards reducing food loss at our breakfast buffet.

Locations participating in TABETE food-sharing program

Mitsui Garden Hotels (Toyosu PREMIER, Otemachi, Gotanda, Sendai, PRANA Tokyo Bay, Yokohama Minatomirai PREMIER, Kanazawa, Nagoya PREMIER, Okayama, Hiroshima, Fukuoka Nakasu, Kumamoto)

  • *TABETE is a food loss app that aims to combine "business" and "social contribution" while ensuring sales economically, a relatively new "mechanism" to the food sharing service.

Utilization of leftover food

We have asked Farm Service LLC to make use of the leftovers from breakfast. We sort the leftovers by type in an effort to reduce CO2 emissions, for example those which require heat treatment, those which require crushing and those which can be used as-is. We also make use of any leftovers which can be fed to pigs.

CO2 reduction amount
  • October 2023 - March 2024: 5,948㎏
  • April 2024 - March 2025: 17,553㎏
