The Great Keyaki of Higashine is a majestic Japanese Zelkova tree located within the playground of Higashine Elementary School in Yamagata Prefecture. This tree is a designated Special Natural Monument of Japan. Its age is estimated to be at least 1,000, and potentially over 1,500 years. The scale of this giant is truly impressive, reaching a height of approximately 28 meters, with a circumference of 24 meters and a trunk diameter of 5 meters. While local lore suggests there were once two trees—the 'Male' and 'Female' Keyaki—today, this single, magnificent tree stands as the 'Yokozuna (Grand Champion) of the East,' serving as a cherished symbol of the local community. It is not merely a natural landmark but also a spiritual pillar deeply connected to the local history and education of the area.
The tree is rooted in the site of the former main enclosure (Honmaru) of Higashine Castle (also known as Odajima Castle), which was built around 1347 during the Nanboku-cho period by Odajima Nagayoshi. Historical maps from the late Edo period reveal that many other zelkova trees once surrounded this area. In the Meiji era, the 'Male Keyaki' existed alongside the current tree, but it withered away in 1885, leaving the current single giant. In 1957, the tree's immense historical and botanical value was officially recognized when it was designated as a Special Natural Monument. The presence of such an ancient living being on the site of a historical castle fortress speaks volumes about the deep historical layers of this land.

The greatest draw is its overwhelming physical presence. The massive trunk splits into two branches at about 5.5 meters above the ground, spreading wide toward the sky, creating a striking silhouette. Another fascinating feature is a hollow near the base of the trunk, believed to be a remnant of where fires were once burned. Local legend says that passing through this area can bring blessings for fertility and children. Visitors can experience a unique blend of natural beauty and the weight of centuries of human history.
The Great Keyaki displays different faces throughout the seasons. 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 brilliant colors, offering a beautiful seasonal landscape. For the best experience, visiting during daylight hours is recommended to observe the intricate textures of the bark and the unique hollow at the base.
Visiting the tree is a peaceful experience of quiet contemplation. Since it is located within the grounds of Higashine Elementary School, it serves as a living classroom for local children, fostering a deep understanding of nature and culture. The surrounding environment still carries the atmosphere of the old castle site, allowing for a tranquil stroll through history.
Near the Great Keyaki, you can explore the 'La La La Street,' a shopping district that retains the nostalgic atmosphere of an old castle town. Additionally, Higashine City is famous as the 'Fruit Kingdom' of Japan, so the surrounding area offers many opportunities to enjoy seasonal fruit harvesting and the lush natural environment.
