This garden in Kokubunji has a storied history. It was established between 1913 and 1915 on the grounds of a villa built for the vice president of the Manchurian railway, Eguchi Teijo, and was later purchased by the founder of Mitsubishi, Iwasaki Yataro, in 1929, who added a tea house to the premises.
Tonogayato’s beauty lies in the diversity of its landscape, which features a waterfall leading to a natural spring. It's also renowned for its bamboo grove and lush forest, a designated cultural asset of Tokyo.
