Summer Purification Ritual (Kuzuryu Shrine)
Source:Official website
A newly constructed Kuzuryu Shrine was established in 2000. Located next to Hakone Shrine, it is accessible on foot from Moto Hakone, making it easier to visit than the main shrine.
At this newly constructed shrine, a ritual event called "Nagoshi no Oharae" is held every year on June 30th. It's a time to give thanks for safely passing through the first half of the year and to pray for a refreshing remainder of the year.
The large ring made of Japanese nutmeg tree, called "Kaya," installed at the entrance of the shrine, is a symbol of Nagoshi no Oharae. It is said that by passing through it in a figure-eight pattern, one can escape illness and calamity and live a healthy life.
The Hakone event & festival June 2025 season offers visitors a unique opportunity to experience traditional Japanese culture while enjoying the natural beauty of the region. The hydrangea blooms combined with these ancient rituals create a perfect backdrop for tourists seeking authentic cultural experiences in Japan.
When You Visit Kuzuryu Shrine, Also Visit Hakone Shrine and Hakone Mototsumiya Shrine!
When visiting Kuzuryu Shrine, you should definitely visit Hakone Shrine as well. Hakone Shrine was established in the same year as Kuzuryu Shrine, 757, allowing you to experience its long history. It is said to have benefits for warding off evil and bringing good luck, and is beloved as the most powerful spiritual spot in Hakone.
The shrine has spacious grounds rich in nature, and its beautifully vermilion-painted main shrine and structures give you a sense of traditional Japan. The shrine gate called "Torii" installed along the lakeshore is known as "The Peace Torii" and is also a symbol of Lake Ashinoko.

Hakone Mototsumiya Shrine is located at the summit of Mt. Hakone Komagatake at an altitude of 1356m. Although it was established relatively recently in 1964 as the rear shrine of Hakone Shrine, Mt. Hakone Komagatake has long been a place where mountain faith was practiced.
Mountains are considered mystical entities that provide people with abundant natural blessings. It was believed that gods resided in such mountains, and people have worshipped them since ancient times.

Natural Attractions of Hakone in June
When speaking of June flowers in Japan, Hydrangea comes to mind. It's a native Japanese flower with many small petals forming a unique ball-like appearance. It's also unique in that the flower color changes depending on the amount of aluminum in the soil, allowing you to enjoy a variety of beautiful colors from pink to blue.
The word Hydrangea comes from the Greek meaning "Water pot," and displays vibrant beauty even on rainy days. June is a rainy season, but Hydrangeas beautifully color the damp days of June.
