We serve soups and cocktails made with vegetables grown using compost derived from water chestnuts.
We will be offering soups made with sustainable vegetables (corn and onions) grown using compost derived from water chestnuts (Hishi) from the Imperial Palace Outer Garden moat at 16 Royal Park Hotels and the dining restaurant "BAY GRILL." In addition, we will be selling original cocktails made with pumpkin exclusively at 5 hotels of the Iconic brand.
This project connects urban and rural areas through a cyclical process, bringing the fruits of our labor to our customers once again this year. We are involved in the environmental restoration of the Imperial Palace Outer Garden moat, an oasis in the heart of the city; farmers who are particular about their soil and fertilizers to cultivate vegetables; and chefs and bartenders who elevate these ingredients into delicious soups and cocktails.
Sustainable Soup
Corn and onions grown in the Yatsugatake Mountains are cooked in a way that brings out the sweetness and flavor of the fresh corn and onions while they are still fresh, under the supervision of the group's Executive Chef, Masaki Matsuyama, and are then turned into soup.
corn soup
Fresh corn, delicious even when raw, is made into a refreshing chilled soup. The slight saltiness brings out the sweetness and umami, and the corn is deliberately left whole to create a smooth texture, allowing you to enjoy the natural sweetness of the ingredients.
Onion soup
This warm soup not only allows you to enjoy the sweetness of onions, but also the deep richness and aroma that is brought out by adding butter and sautéing.
It's a comforting taste that seeps into your body and soul.

Mitsubishi Estate Group's sustainable initiatives utilizing resource recycling
Since 2017, the Mitsubishi Estate Group has been collaborating with the Ministry of the Environment's Imperial Palace Outer Gardens Management Office on the "Moat Project," an initiative aimed at restoring the waterside ecosystem and preserving biodiversity in the Imperial Palace Outer Gardens moat in Marunouchi, Tokyo.
Since 2019, the company has been composting the waterweed "Hishi" (water chestnuts) harvested during the Ministry of the Environment's maintenance of the Imperial Palace Outer Garden moat, and working with organic farmers in Yamanashi Prefecture, the company has cultivated vegetables using this compost, which are then used as ingredients in the cafeteria at Mitsubishi Estate's headquarters, among other places, building a resource circulation system that connects urban and rural areas.
