In 1884, Shigenobu Ōkuma, the founder of Waseda University, remodeled the garden into semi-Western style.

He placed a vast lawn, artificial hills, and ponds, and grew melons in a hothouse for the first time in Japan.

The garden features an extensive lawn, brooks, seasonal plants and walking paths.

Reduced-size replica of “Shotoku-Daiou-Shinkyo” which was donated by the Korean graduates’ association in commemoration of the 100th anniversary of the university, now adorns the garden.

Okuma Garden is located approximately 5 minutes' walk from Waseda Station, and it is open from 11:00 until 16:00 on Monday, Tuesday, Thursday, and Friday during the semesters, April to December.
