Surrounded by the greenery of Outer Moat Park and the forest of Yasukuni Shrine, the "Boissonade Tower" stands tall and is a landmark in the surrounding area. The modern all-glass Sotobori Building, the Fujimi Gate with its distinctive large frame in the summer of 2016, and the Ouchiyama Building, which inherited the design of the 55/58 Building, were completed in the spring of 2019, transforming the campus into an urban campus for a new generation.
