Approach to SustainabilityApproach to Sustainability


The energy system that powers HOSHINOYA Karuizawa is called “EIMY (Energy in My Yard).” The self-sufficient energy system, which makes use of hydroelectric and geothermal energy, was built on the simple concept of a resort generating and supplying the energy it consumes to minimize its burden on the environment in keeping with a resort whose theme is based on the rich natural environment. The river flowing through the center of the facility fulfills the role of the dam for hydroelectric generation.


Eco-Tourism in Karuizawa

To uphold the aspirations of those who have loved the natural environment of Karuizawa before us and to protect the ecology for future generations, we launched picchio* in 1992. This company is now expanding its activities to include eco-tourism.

  • Picchio, which means “woodpecker” in Italian, is a Hoshino Resorts Group company that is dedicated to ensuring the survival of forests and the creatures that live there for the future.
