Stroll through an iris field on the banks of the Edo River

Buildings may dominate Tokyo, but if you know where to look there is a wealth of nature available within the city. Koiwa Shobuen is a garden running along the banks of the Edogawa River that is home to over 50,000 iris flowers from a hundred different species. The garden bursts into a sea of pink and purple when the irises are in bloom from May to June. Make sure to bring your camera; this is not a sight you want to miss.

The area surrounding the garden has walking paths, and baseball and softball courts busy with activity throughout the year.
