Although known for being a famous sakura cherry blossom spot since long ago, hydrangeas also beautifully bloom in June at this park.

Hydrangeas grow on the east side of Asukayama Park, 1,300 of the plants blooming along "Asukanokomichi," a narrow path along the rails of JR Oji Station. They are planted on the surface to the side of the course so that you can view them up close.

Also, within Asukayama Park, there is a museum that presents the history, nature, and culture of Kita-ku and a museum all about paper.

From early May every year, around Ueno Park, hydrangea start to bloom, and you can enjoy colorful flowers until early July. You can also walk around Shinobazu-dori Ave., which is lined by beautiful hydrangea.

Hakusan-Jinja of Bunkyo-ku and the adjacent park Hakusan-Park have around 3,000 Ajisai growing, and from early June to mid-June, the Hakusan-Jinja Ajisai Festival is being held.

Besides booths selling all sorts of beautiful hydrangeas, there are also many food stalls serving delicious snacks to visitors. There are also various events taking place on the festival's Saturdays and Sundays, such as small concerts.

Hakusan Shrine is famous for another particular thing: the shrine is believed to cure toothache, and on the 11th as well as on the 18th of June, both Sundays, a toothbrush memorial service is being held!

One of the most influential feudal lords of the Edo period (1603 ~ 1886), Tokugawa Yorifusa, commissioned a Japanese garden in 1629 that his son, Tokugawa Mitsukuni, then completed. Today, the beautiful garden is under the management of the City of Tokyo.

In the 70,000 square meters of the vast park blossom, various seasonal flowers, the around 700 Hanashobu, Japanese irises, blooming from the end of May to mid-June, are a magnificent sight to behold.

The wooden footpath built during this period lets visitors experience the flowers up close. Right next to the garden lies Tokyo's very first roofed stadium, Tokyo Dome.

On the banks of the Edogawa River, flowing through the same-named district of Edogawa-ku, lies Koiwa Iris Garden, or Koiwa Shobuen.

The 50,000 irises that blossom here between late May and June have become a metropolitan attraction. The many irises were donated by residents one after the other, and Edogawa-ku has slowly expanded the park until it has become a full circle-style garden. This round shape is one typical form of Japanese garden, created to allow visitors to appreciate the grounds in their entirety by being able to circle it completely.

Feel free to stroll along the circle path leisurely and enjoy the magnificent sight of a sea of blue irises.
