Guide
Yasutomi-zakura is a magnificent Edohigan single-tree cherry blossom located in Iida City, Nagano Prefecture. The tree is truly massive, with a trunk circumference of approximately 5.4 to 6 meters and a height reaching about 20 meters. It takes its name from the Yasutomi family, who served as high-ranking officials (Karo) for the Iida clan. As an Edohigan variety, it is characterized by blooming around the spring equinox (around March 17–23), producing a stunning display of flowers before the leaves emerge. It is one of the largest and most significant cherry trees in the Iida area.
The history of this tree is incredibly deep, with origins estimated back to the era of Mori Chimasu, the first lord of the Iida clan. With an estimated age of over 400 to 450 years, it has witnessed centuries of local history. The tree stands on the site of a former residence of the Yasutomi family, high-ranking officials of the Iida clan. This area was once a vital part of the Iida Castle-town. Furthermore, from 1921 to 1982, the site was home to Iida Chihime High School (the predecessor to the current Iida OIDE Chihime High School). Today, the tree is recognized as a Natural Monument of Nagano Prefecture (specifically as the 'Chihime Edohigan').
The most striking feature is its powerful, massive structure. The trunk splits into several thick branches about 3 meters above the ground, creating a unique shape where five heavy limbs spread out like a broom. The sight of the delicate pink blossoms completely covering the branches before the leaves appear is a quintessential spring scene. The tree is located within the grounds of the Iida City Art Museum, allowing visitors to enjoy both natural beauty and cultural enrichment.
The best season to see Yasutomi-zakura is from mid-March to April. The period around the spring equinox is particularly beautiful as the flowers bloom in high density before the foliage develops. For the most accurate blooming updates, please check the 'Sakura Saku' section of the official Iida City website. Visitors can enjoy the contrast of the pale pink blossoms against a blue sky during the day, or a more serene, tranquil atmosphere during the evening hours.
Since the tree is located on the grounds of the Iida City Art Museum, you can combine your cherry blossom viewing with a cultural visit. The museum offers unique exhibits, including the only full skeleton reconstruction of a Spinosaurus in Japan, as well as a planetarium. This allows for an intellectually stimulating stroll that blends the vitality of nature with local art and science.
Beyond the museum gardens, the area is rich with the culture of the Ina Valley. You can explore various facilities related to local history and the works of Kunio Yanagita. Walking through the streets of the former Iida Castle-town offers a glimpse into the past, while the museum's unique architecture—inspired by the Southern Alps—adds a modern aesthetic touch to the landscape.
