Earth-friendly, Community-friendly, and People-friendly hotel

Efforts of our hotel


Lettuce cultivation using electricity derived from food waste

We have conducted Leaf lettuce cultivation to realize a low-carbon society (CO2 reduction) by utilizing electricity derived from food waste not only for hotel electricity but also for plant cultivation. Lettuce can be grown so fast and large that we harvest it within 30 ~ 40 days from seeding and about 40 plants per week by irradiating red and blue LEDs alternately in an environment with a temperature of 22-26 degrees Celsius and humidity of 60-80%. We serve the harvested lettuce in the hotel's restaurant.

Introduction of Bio food Recycling

We have introduced bio food recycling, which converts food waste into renewable energy. In addition to achieving a 100% recycling rate of food waste from the hotel, we are participating in an initiative to generate electricity by running a gas engine on biogas generated by methane fermentation of waste by microorganisms. Furthermore, we have established a system of "utilization of local circulating energy" by purchasing the electricity.



We have introduced amenities made from rice husks and other plant-derived resources to reduce the burden on the environment,.
Toothbrush and leather (35% rice husks each), hairbrush (12.5% rice husks), shower cap (20% cornstarch), body towel (100% cotton)


Installation of water servers

We have installed water servers on each floor, eliminating the use of plastic-bottled mineral water provided free of charge in guest rooms. This has enabled a reduction of approximately 20,000 plastic bottles of waste per year. In addition, we are using eco-friendly "forest tumblers" as cups for guests to carry water from the water servers to guest rooms. These eco-friendly cups are made of 55% cellulose fiber, a wood-derived material.
