Located in Saigo Village, Nishishirakawa District, Fukushima Prefecture, "Kenkei" is a magnificent Katsura tree standing approximately 35 meters tall with an age exceeding 300 years. The tree is characterized by its unique "twin-trunk" structure, where two massive trunks diverge from a single root, giving it the striking appearance of a sword—hence the name "Kenkei" (Sword Katsura). In 2000, it was officially recognized by the Forestry Agency as one of the "100 Great Trees of the Forest," marking it as a significant natural heritage site for the region.
The site is steeped in ancient folklore. Legend has it that a malevolent spirit or "demon" once haunted this land, causing suffering to the local people. It is said that the local lord, Matsudaira Sadanobu, used a sword to seal the demon away, and this tree became a symbol of that victory. Because of this historical narrative, the tree is not merely a botanical specimen but a revered symbol of protection and spiritual significance that has been cherished by the local community for generations.

The primary focus is the two massive trunks that soar straight toward the sky. The sculptural form, shaped by over 300 years of growth, serves as a powerful visual testament to the strength of nature. Because the tree is significantly taller than the surrounding vegetation, its imposing presence can be spotted even from a distance. The changing expressions of the tree through the seasons offer a different sense of awe every time you visit.
While the tree can be observed year-round, the autumn season is particularly spectacular. During this time, the changing colors of the surrounding landscape create a beautiful contrast with the massive structure of the tree. For the best view of the texture of the bark and the intricate structure of the twin trunks, we recommend visiting during bright daylight hours. We suggest dressing appropriately for the outdoor environment to enjoy the peaceful silence of nature.
The main activity here is the quiet contemplation of nature's architectural beauty. By looking up from the base of this 300-year-old giant, visitors can experience a profound sense of scale and the passage of time. The surrounding area is rich in natural beauty, making it an ideal spot for a meditative stroll and nature observation.
The area around Saigo Village is characterized by lush, natural landscapes. Travel in this region is primarily done by car. There are various hot spring facilities and scenic spots nearby to enjoy.
