Guide
The Higashine no Okeya-ki is a magnificent Keyaki tree located within the courtyard of Higashine Elementary School in Yamagata Prefecture. With an estimated age of 1,000 to 1,500 years, its scale is truly overwhelming: it stands approximately 28 meters tall, with a circumference of 24 meters and a diameter of 5 meters. While legends suggest there were once two trees—a male and a female Keyaki—this single, massive tree, often called the 'Yokozuna of the East,' remains a cherished symbol of the local community. It is more than just a natural landmark; it serves as a spiritual pillar deeply connected to the local history and education of the area.
The tree is rooted in the former site of the main enclosure (Honmaru) of Higashine Castle, which was built around 1347 by Oda-jima Nagayoshi during the Nanboku-cho period. Historical maps from the late Edo period show that many other Keyaki trees once surrounded this area. In the Meiji era, a 'female' tree existed alongside this 'male' tree, but after the female tree withered in 1885, only this single giant remains. In 1957, its immense historical and botanical value was officially recognized when it was designated as a Special Natural Monument of Japan. The presence of such an ancient living being on the site of a former castle stronghold speaks volumes about the deep history of this land.
The most striking feature is its sheer presence. The massive trunk splits into two thick branches at about 5.5 meters above the ground, spreading wide toward the sky. At the base of the trunk, there is a hollow space where locals believe fires were once lit; a local legend even suggests that passing through this area can bring blessings for fertility and children. Visitors can experience a profound sense of time through the combination of natural beauty and centuries of human history.
The Keyaki tree displays a different face with every season. In mid-May, you can witness the vibrant energy of life as fresh, light-green leaves sprout from the old branches. In autumn, the tree transforms with beautiful colors, providing a stunning landscape of changing hues. Daytime is the best time to visit to observe the intricate textures of the bark and the details of the hollow at the base.
The primary way to enjoy this site is through quiet contemplation. Since the tree is located within the grounds of Higashine Elementary School, it serves as a living classroom for local children, fostering a connection between the community and nature. The surrounding environment, which still carries the atmosphere of the former castle site, provides a peaceful space for reflection.
Near the tree, you can explore the 'Okeya-ki La La La Street,' a shopping district that retains the charm of an old castle town. Higashine City is also famous as a 'Fruit Kingdom,' so visitors can enjoy seasonal fruit harvesting and the lush natural environment of the surrounding orchards.
