Nestled in the mountains of Appi Kogen, within the rich natural landscape of Hachimantai, Harrow International School Appi Japan is profoundly shaped by its surroundings. We recognise how fortunate we are to learn and live in such an extraordinary environment, and with that privilege comes responsibility.  

Harrow Appi is proud to be recognised as a Sustainable School, where environmental stewardship, education, and action come together. Our commitment to sustainability goes far beyond reducing emissions. As an educational institution, our greatest impact lies in how we educate young people to understand, value, and protect the natural world, and how we model those values through our daily practice as a school. 

Powering Quality Education with Clean Energy

As of 1 March 2025, Harrow Appi became the first international school in Japan to operate on 100% geothermal electricity. All electricity used across our mountain campus is now fully carbon neutral, marking a major milestone in our sustainability journey.

This geothermal transition was made possible through close collaboration with Hachimantai City and GeoPower, a sustainable energy company established to harness the region’s rich geothermal resources. Located in a volcanic region with exceptional geothermal potential, Hachimantai offers one of the most viable clean energy landscapes in Japan. The school worked closely over an extended period with city officials and energy experts to plan, design, and implement the transition. 

By switching entirely to geothermal energy, Harrow Appi is projected to reduce over 400 metric tonnes of CO₂ emissions annually—equivalent to removing nearly 90 passenger cars from the road every year.
