Oubai-in is a Zen temple located in Iida City, Nagano Prefecture. The most iconic feature of this temple is the magnificent Beni-shidare (Red Weeping Cherry) tree standing near the Sanmon gate. The tree is approximately 18 meters tall and 5.5 meters in circumference, with an estimated age of 400 years. It is officially designated as a natural monument of Iida City. The cherry blossoms are characterized by a deep, reddish hue and a beautiful umbrella-like shape. A unique characteristic of this tree is how its appearance changes with the weather; the blossoms can appear much lighter or even white-ish during rainfall, offering a different expression than on sunny days.
The history of Oubai-in is deep and storied. It was originally founded in 1582 in Shimada Village (now Matsuo, Iida City) before being moved to its current location by order of the Wakisaka clan, the lords of Iida Castle. Local legend also suggests it was established as a memorial temple for Princess Oubai, the daughter of the famous warlord Takeda Shingen and his wife Lady Sanjo. The temple has faced significant challenges, including the Great Fire of the Genroku era, which destroyed the main hall and kitchen buildings. Historically, the temple was also a center for people gathering to pray for successful silkworm cultivation.

The centerpiece of the temple is undoubtedly the Red Weeping Cherry. This ancient tree radiates an overwhelming presence, symbolizing the traditional Japanese landscape. Visitors can also observe the historical architectural styles 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 blooming season, the harmony between the vibrant blossoms and the historic temple architecture creates a truly striking scene.
The best time to visit is during the spring cherry blossom season. The deep red color of the Beni-shidare is particularly vivid during full bloom. Because the color of the flowers changes depending on the weather, seeing the tree during a light rain can offer a unique and poetic experience. Additionally, the temple maintains seasonal traditions, such as the 'Sekishiki' ceremony held on August 3rd.
Visitors can enjoy the tranquil atmosphere of a historic Japanese temple while admiring the natural sculptural beauty of the ancient cherry tree. The area is steeped in the culture of a former castle town related to Iida Castle. You can also explore the surrounding historical streets and learn about the local heritage while walking through the peaceful temple grounds.
The area around Oubai-in in central Iida City is nestled between the Matsukawa and Nodogawa rivers and features more than ten other temples. Many of these sites also house ancient cherry trees, making the entire neighborhood a beautiful historical landscape. For deeper insights into the local history and the development of the castle town, visitors can consult the 'Iida Castle Guidebook' at the Iida Central Library.
