Tetsugakudo Park

Tetsugakudo Park is a philosophy-themed park established in 1904 by Inoue Enryo, the founder of Toyo University. It was designated a Tokyo Metropolitan Place of Scenic Beauty in 2009 and a national place of scenic beauty in March 2020. At Jiku-Kou Hill within the park, there are a group of uniquely designed ancient buildings designated as tangible cultural properties of Nakano Ward, including the Shisei-do Hall, which enshrines Buddha, Confucius, Socrates, and Kant, philosophers from all over the world, past and present; the Rokukendai Hall, which enshrines six wise men from the East, including Prince Shotoku and Sugawara no Michizane; and Zettai Castle, which was used as a library at the time.
