Rikkyo Ikebukuro Junior and Senior High School stands as a notable example of late twentieth-century educational architecture in Tokyo's Toshima Ward. Completed in 1999, this comprehensive institution serving elementary through high school students showcases the collaborative design vision of Mana Architectural Design Studio and Yamashita Sekkei. Located in the vibrant Nishi-Ikebukuro district, the building integrates functional educational spaces with contemporary architectural principles. The design reflects the approach of two respected Japanese firms in creating an environment that balances pedagogical requirements with aesthetic considerations, making it of particular interest to those studying modern school architecture and institutional design in Japan.
