Guide
Katahara Onsen Ajisai no Sato is a tranquil hot spring resort located in Gamagori City, Aichi Prefecture, where visitors can truly feel the changing of the seasons. The highlight is the annual "Ajisai (Hydrangea) Festival" held throughout the month of June. During this time, approximately 50,000 hydrangea plants bloom in full glory, creating a breathtaking sea of color that attracts visitors from far and wide. It is a perfect place to unwind and enjoy the natural beauty alongside traditional Japanese hot spring culture.
The region has long been deeply connected to the culture of hot springs (onsen). The development of the area as a "Hydrangea Village" is part of a dedicated effort to celebrate and preserve the beauty of seasonal flora. The annual Ajisai Festival and the "Japan Hydrangea Exhibition," which showcases rare and unique varieties, have become established cultural events that highlight the region's natural resources. Additionally, the area hosts events like tourism photography contests, serving as a place where visitors can capture and share the fleeting beauty of the landscape.
The greatest draw is the spectacular sight of 50,000 hydrangeas in full bloom during June. This sea of blossoms is truly an overwhelming experience. To enhance the beauty, the gardens are illuminated from sunset until 9:00 PM (until 9:30 PM on Saturdays). The night-time light-up offers a completely different, mystical atmosphere compared to the daytime. Furthermore, the "Japan Hydrangea Exhibition" features over 100 varieties of rare hydrangeas, offering a deep dive into the diverse beauty of these plants.
The most recommended time to visit is between May and July, with June being the absolute peak when the hydrangeas are in full bloom for the festival. While the vibrant colors are stunning during the bright daylight hours, the night-time illumination is a must-see. The way the light dances on the petals in the quiet night creates a magical, unforgettable experience.
There are various ways to engage with the scenery depending on your interests. You can deepen your botanical knowledge through hydrangea-related workshops or participate in the local tourism photography contests. The resort often organizes events using original photo frames, encouraging visitors to capture and share their unique perspectives. It is a place where you can fully immerse yourself in seasonal events and the soothing warmth of the onsen.
