Meigetsuin Temple, also known as Ajisaidera or the Hydrangea Temple, is a historical site in Kamakura, Japan. Founded in 1160 by Yamanouchi Tsunetoshi for his father Toshimichi, it is primarily dedicated to the Zen Buddhist Kannon Bodhisattva. Built as part of a larger complex which was later divided, Meigetsuin is known for its lush garden and the beautiful hydrangeas that bloom in June. The temple's name, which means 'Bright Moon Temple,' was derived from a line in a Chinese poem that reflects tranquility. Visitors can explore the serene main hall, a contemplative rock garden, and the famous circular window framing the garden behind it. The window represents enlightenment in Zen philosophy and offers a perfect view of the natural surroundings that change with the seasons. In addition to the spectacular floral display, the temple grounds also include a bamboo grove and a burial area for the Hojo clan. Meigetsuin is emblematic of Kamakura's historical and cultural significance, making it a profound destination for both spiritual reflection and appreciation of nature's beauty.
