June is the best time to see hydrangeas in Tokyo. You’ll see bursts of blue and pink ajisai all around the capital.

Here are some of our favorite spots to see this underrated summer flower around Tokyo, besides the beloved Bunkyo Ajisai Festival.

Did you know? The color of a hydrangea is largely determined by the pH of the soil. A more acidic pH results in blue blooms, while more alkalinity fetches pink flowers.

Hydrangea FAQs

When are hydrangeas in bloom in Japan?

June is peak season. Most festivals run between late May and the end of June.

How long do the flowers last?

Typically 2–3 weeks, depending on the weather.

What kinds of hydrangeas do you get in Japan?

Hydrangeas in Japan fall into a few main types. The classic round ones are hon-ajisai or true hydrangea, while gaku-ajisai have flatter heads with tiny flowers in the middle and larger petals around the edge.

You’ll also sometimes see yama-ajisai, a more delicate mountain hydrangea, and Annabel hydrangeas, which are popular for their big white blooms.

Do hydrangeas bloom in the rainy season?

Just as cherry blossoms signal spring, hydrangeas signal the start of the rainy season in Japan.

Fun fact: Because of their shifting colors, hydrangea flowers are often associated with change, transience, and mixed emotions.
