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 Edo River that is home to over 50,000 iris flowers donated by local residents. The garden bursts into a sea of pink and purple when the irises are in bloom from May to July. Make sure to bring your camera; this is not a sight you want to miss.

The area surrounding the garden has walking paths, soccer fields and softball diamonds busy with activity in the warmer months.
