Along with hydrangeas, irises are one of the colorful floral highlights of Japan's rainy season. This guide covers five great places to enjoy irises across the country.

Suigo Sawara Ayame Park, Chiba

Chiba's Suigo Sawara Ayame Park is home to an annual iris festival with 1.5 million flowers for visitors to enjoy. When the flowers are in full bloom, the park shop sells a range of different local products, souvenirs, and even iris plants if you'd like to try growing your own at home.

For those who enjoy hands-on experiences, it's worth checking out the events and classes held during the festival dates, including workshops on how to separate iris roots in order to propagate more plants.

Fukiage Iris Park, Tokyo

Each year during June, Fukiage Iris Park on the outskirts of Tokyo sees thousands of irises bloom in numerous different varieties. The flowers are set up in a color gradient format, with deep purples progressing into lighter purples, all the way to white ones.

Throughout the park there are boardwalks where visitors can stroll along to appreciate the flowers up close, and in typical years there are also food booths selling things like yakitori (skewered grilled chicken) and yakisoba (fried noodles). Admission to the park during iris season is priced at a very reasonable 200 yen.
