Guide
Obai-in is a Sodo sect Buddhist temple located in Iida City, Nagano Prefecture. The temple's most iconic feature is the magnificent Red Weeping Cherry tree standing beside the Sanmon (mountain gate). Reaching approximately 18 meters in height with a trunk circumference of about 5.5 meters, this ancient tree is estimated to be around 400 years old and is officially designated as a natural monument of Iida City. The blossoms are characterized by a deep, intense reddish color, creating a striking umbrella-like shape. A unique phenomenon occurs during rainfall: the blossoms appear to change from their deep red to a softer white, resembling the delicate appearance of Spirea flowers.
The history of Obai-in is long and storied. It was originally founded in 1582 in Shimada Village (present-day Matsuo, Iida City) before being moved to its current location by order of the Wakisaka clan, who ruled Iida Castle. Local legends also connect the temple to the Takeda clan, noting it as the memorial temple for Princess Obai, the daughter of the famous warlord Takeda Shingen. The temple has faced significant history, including the 'Obai-in Fire' during the Genroku era, which destroyed the main hall and priest quarters. Historically, the temple was also a center for community gatherings to pray for successful sericulture (silk farming).
The centerpiece of the temple is undoubtedly the Red Weeping Cherry tree. This ancient tree radiates an overwhelming presence, symbolizing the traditional Japanese landscape. Visitors can also observe the historical architectural details of the Main Hall and Sanmon gate, which feature the 'Umebachi' (plum blossom) crest of the Hori clan, the former lords of Iida Castle. During the cherry blossom season, the contrast between the vibrant flowers and the weathered temple structures creates a sublime atmosphere.
The most spectacular time to visit is during the spring cherry blossom season. The deep crimson colors are most vivid when the tree is in full bloom. Because the blossoms change appearance based on the weather, the temple offers a different aesthetic during sunny days versus rainy days. Additionally, the temple maintains seasonal traditions, such as the 'Sekishiki' ritual held on August 3rd.
Visitors can enjoy the tranquil atmosphere of a historic Japanese temple while admiring the sculptural beauty of nature. The area is deeply connected to the history of Iida Castle and its surrounding castle town. A stroll through the nearby historical streets and exploring the local temple-rich landscape offers a deep dive into the cultural heritage of the region.
The center of Iida City, situated between the Matsukawa and Nadiso Rivers, is home to over ten temples, many of which feature ancient cherry trees, creating a beautiful historical landscape. For those interested in local history, the Iida City Central Library offers the 'Iida Castle Guidebook,' which provides detailed information on the development of the castle town.
