The Plastic Problem

Our school's manually-operated panel heaters for room heating have low fuel efficiency because they have no algorithm regulating their heat output and stay on even when nobody is around. Project H-RACS provides an IoT solution to automating these radiators. This efficiently uses fuel, not only decreasing heating cost, but also maintaining a temperature that is just-right for the classroom. By using our resources more efficiently, project H-RACS is creating a more sustainable school.

Restoring Hope supports 36 displaced girls in Mekelle, Tigray, Ethiopia, who were affected by the Tigray War. Combining psychological rehabilitation with educational reintegration, the project helps them rebuild confidence, emotional wellbeing, and motivation to return to school in a safe and supportive environment.

Teacher orientation is a flood of new information to digest — teachers feel overwhelmed and underprepared. When faced with challenges in the classroom or procedures to follow, the right information is rarely at hand. The result is stressed teachers and inconsistent application of school approaches.Decision Point uses bespoke simulations so teachers can make decisions in a low-stakes environment. The result is more confident teachers, less procedural error, and less administrative burden.

Inspired by my grandfather’s hearing loss, I See Life works to bridge the gap between deaf and hearing communities. Through exchange trips and activities to a local deaf school, weekly sign language sessions, and events on World Hearing Day, we encourage more people to connect with the hard of hearing community, one that often gets overlooked in our daily lives. #DeafAwareness #Inclusion #SignLanguage #TechForGood #uwc #uwcisakjapan #isakimpactawards #isakimpact #nagano #karuizawa

Our mission is to make ISAK a place where taking action becomes the norm, and where every student has the courage to turn "zero into one." We hosted Entrepreneur Weekend twice during our Grade 10 year, bringing together ISAK students and middle and high school students from across Japan to develop startup ideas over three days, with mentorship from professional entrepreneurs. As we moved into Grade 11, we began sending Grade 10 students to Startup Weekend events in Tokyo and Nagoya, creating a cycle where students pass down the mindset of leadership to future cohorts.

Grade 12 student Kellen discovered a deforested clearing behind UWC ISAK Japan and decided to take action. Inspired by the Miyawaki Method, he launched the Pocket Forest CAS project and navigated bureaucratic challenges to create Kaohsiung, Taiwan's first Miyawaki Forest. With local support, volunteers planted 240 native saplings, restoring biodiversity in an industrial area. His leadership demonstrates how education empowers students to turn environmental awareness into tangible impact, building frameworks for ecological and personal regeneration.

Nagano Harvest is a student-led CAS initiative at UWC ISAK Japan focused on sustainable agriculture and community learning. Through hands-on farming experiences in Nagano, students explored practical methods of more sustainable food production while building a deeper understanding of the relationship between people, land, and food systems.The project aimed to bring this learning back to the ISAK community by helping students better understand where their food comes from and why responsible farming practices matter. By growing food, working with local agricultural knowledge, and sharing their experiences, the team encouraged the community to think more carefully about food consumption and sustainability.Nagano Harvest highlights how small, practical actions can strengthen connections between students and the local community of Karuizawa while promoting more thoughtful and sustainable approaches to agriculture.

We tackle coffee waste by combining science with community action. Our team engineered E. coli to remove caffeine from spent coffee grounds, making them safe for use as fertilizer. Beyond the lab, we partnered with coffee shops, taught students through workshops and camps, and brought sustainability education to rural communities, empowering people to turn everyday waste into a resource.

I've long cared about sustainability and saw an opportunity at ISAK to make a difference. I initiated ISAK Soap, a faculty-led CAS project where students and I learned to make soap using our school's recycled cooking oil to reduce plastic waste and replace commercially-made cleaning products. Students have embraced this environmentally-friendly option and are eager to support UWC's sustainability mission. We've sold various soaps, and profits fund continued experimentation with new varieties, allowing the project to grow sustainably.
