The park was created specifically to showcase the variety of hydrangea, which is the meaning of 'Ajisai' in Japanese.
The peak blooming period typically aligns with the Japanese rainy season, known as tsuyu, occurring in June.
Kodaira City maintains this site as part of its 'Green Road' initiative, connecting various public spaces throughout the municipality.
The park is compact and designed as a dense garden rather than a wide-open recreational field.
Ajisai Park is a specialized urban park in Kodaira, Tokyo, renowned for its extensive collection of hydrangeas. The park features over 1,000 hydrangea bushes representing approximately 30 different varieties. Its landscape is designed to highlight the seasonal transitions of these flowers, which bloom throughout the paths. The park is managed by the City of Kodaira as part of the regional green network. It serves as a localized destination for botanical interest during the rainy season. The layout is optimized for pedestrian walking, with narrow paths weaving through the dense floral displays.

Visit during a light drizzle to see the hydrangea petals at their most vibrant, as moisture deepens their color.
Bring insect repellent, as the dense foliage and humid conditions in June attract mosquitoes.
The paths are narrow, so visit on a weekday morning to avoid crowding during the peak blooming weekends.
Do not visit outside of the late spring or early summer months if you expect to see the namesake flowers in bloom.
Stay on the designated footpaths to protect the flower beds; do not pick or prune the hydrangeas.
