Hi, I'm Sabi-chan.
How can I help you?
Opened in 2016, the Kamiyama Academic Center (KAC) was funded by founder Haruki Kamiyama. This beautiful, light-filled building is the hub of the campus, featuring classrooms, a library/information center, study areas, meeting rooms, the main school office, and a deck terrace. Its comfy furniture and cozy spaces make the KAC a favorite study spot for students.
The Asama Building houses the cafeteria, science classrooms and labs, and the Imatsu Lounge. The Imatsu Lounge, an extension of the cafeteria, is a versatile space hosting classes, cafe talks, band performances, and serving as a mini-hub for smaller scale community activities on campus.
The Accord Center (TAC), named by one of our founders, is designed as a multi-purpose facility. TAC features movable walls that can be reconfigured to host classes, art exhibitions, school assemblies, and theatre and musical performances, providing a flexible space for a wide range of activities and events.
The Koshiba Innovative and Creative Center, funded by founder Masahiro Koshiba, opened in the summer of 2024. It houses our Film, Theatre, and Arts programs, Outdoor Education, and University Advising offices. The building also features a dedicated maker space and a student lounge, providing a dynamic environment for creativity and learning.
Scheduled for completion by the end of 2024, the Health and Wellness Center was funded by our Representative Founder Mamoru Taniya. It houses nursing facilities, counseling offices, and fitness and meditation rooms.
Our gymnasium features a full-sized basketball court and a bouldering wall. In addition to hosting PE classes and sports activities, it is used for many campus events and proudly displays banners honoring all of our graduating classes. This space is a central hub for both athletics and community gatherings.
Our Community Garden was spearheaded by faculty member Lorier Reygel, who identified a need for exterior gathering spaces on campus. Over several years, Mr. Reygel collaborated with students and other community members to introduce a new, innovative use of the land. This initiative has transformed the area into one of the most popular and enriching spots on campus.
The ISAK Forest was made possible thanks to the efforts of Class of 2019 graduate Yutaro Shimizu, who worked tirelessly to secure a free lease of the land. Later, Class of 2021 students Kai Yamagami and Rin Yokoi envisioned the forest as a place for students and local community members to gather for events, and they secured funding to build a heavy-duty treehouse for community gatherings.
