Located in Kasu City, this residential facility serves as both an accommodation complex and educational institution. The building exemplifies the modernist design principles characteristic of Sakakura's work, blending functional programming with architectural sophistication. As a youth hostel and training center, it plays an important role in community education and group accommodation. The facility demonstrates thoughtful integration of architectural design with social purpose, making it a significant example of late twentieth-century institutional architecture in Saitama Prefecture.
