Matsuoji is a Koyasan Shingon Buddhist temple located in Hotaka Ariake, Azumino City, Nagano Prefecture. Known by the mountain name Iou-zan and the temple name Joraku-in, it is dedicated to Yakushi Nyorai, the Medicine Buddha, who is believed to heal all physical and mental suffering. The temple's centerpiece is the main hall, a National Important Cultural Property that preserves the architectural elegance of the late Muromachi period. Set against the breathtaking natural backdrop of Azumino, the temple serves as a long-standing center of faith and spiritual refuge.
The history of Matsuoji is profound, with origins tracing back to the year 651 (the second year of the Hakuho era). It saw a significant revival in 1528 under Nishina Morimasa, deeply intertwining the temple with local history. The temple's name even appears in the famous works of the Edo-period writer Jippensha Ikku, highlighting its historical fame. Despite the challenges of the Meiji era, the temple's core structures, including the main hall (Yakushido) and the Nio-do, remain as testament to its endurance. The main hall was officially designated as a National Important Cultural Property in 1959.

The most significant attraction is the main hall (Yakushido), a National Important Cultural Property. It features a hip-and-gable roof structure with copper plating, maintaining the architectural style of the late Muromachi period. Inside, a Goma altar is set for fire rituals (Goma Kito) dedicated to Yakushi Nyorai. Visitors can observe various historic buildings throughout the grounds, offering a rare glimpse into traditional Japanese temple architecture and the spiritual depth of ancient rituals.
Matsuoji hosts special religious ceremonies at specific times of the year. Every year, on the second Saturday of April and the first Saturday of November, a special Goma fire ritual is performed. During this ceremony, offerings are cast into a sacred fire at the altar within the main hall. While the interior of the main hall is usually closed to the public, these specific dates offer a rare opportunity to witness the powerful ritual up close. Planning your visit around these dates provides a much deeper cultural and spiritual experience.

Visitors can collect Goshuin (sacred temple stamps). There are two types available: the 'Yakushi Nyorai' stamp and the 'Rurikoden' stamp (the name of the hall where the deity resides). Additionally, visitors can participate in a traditional way of prayer by using the prayer forms placed in front of the main hall. By writing your wishes and placing them in the wooden box, your prayer will be included in the daily morning services (Kugyo) starting the following day, allowing for a personal connection to Japanese Buddhist traditions.
Matsuoji is surrounded by the stunning scenery of Azumino. The area is famous for its natural beauty and historical sites. To reach the temple, you can take a taxi from JR Hotaka Station (approximately 15 minutes). If traveling by car, it is about a 25-minute drive (approx. 14km) from the Azumino IC, making it a perfect stop along a scenic driving route through Nagano.
