The Bunkyo Ajisai Festival began June 6, 2026, at Hakusan Shrine in Tokyo's Bunkyo Ward [1].
This annual event serves as a cultural marker for the arrival of summer and the rainy season, drawing visitors to the local community to celebrate traditional floral displays.
Organized by the Bunkyo Ward and Hakusan Shrine, the festival features approximately 3,000 hydrangea plants [1]. While reports on the variety of the flowers range between 20 [3] and 30 species [1], the displays create a colorful landscape across the shrine and surrounding Hakusan Park.
Beyond the floral exhibits, the festival includes concerts, the sale of potted plants, and the special public opening of the "Fuji-tsuka" [1]. This man-made mound, which stands approximately five meters tall [1], is a historical feature of the grounds. Historical records indicate that about 200 hydrangea plants were planted on the Fuji-tsuka [2].
Visitors described the atmosphere as reminiscent of a traditional downtown festival. "It is very beautiful," a visitor said. "My child finally learned what hydrangeas are and points them out when we walk in the neighborhood, so we came to see them together."
Another visitor said the timing was ideal for the blooms and that the variety of colors created a very enjoyable atmosphere.
The festival continues through June 14, 2026 [1].
“approximately 3,000 hydrangea plants”
The Bunkyo Ajisai Festival blends botanical tourism with the preservation of Shinto shrine traditions. By opening the Fuji-tsuka—a miniature representation of Mount Fuji—alongside the seasonal blooms, the event reinforces the connection between urban Tokyo residents and historical spiritual practices associated with nature and the seasons.
