Shinkai Sansha Jinja is a venerable Shinto shrine located in Saku City, Nagano Prefecture. For generations, this shrine has been deeply woven into the fabric of the local community, serving as a sacred space where significant life milestones and traditional events are celebrated. It plays a vital role in the lives of local residents, hosting ceremonies such as Shichi-Go-San (celebrating children's growth), the first shrine visit for newborns (Hatsumiyamai), and traditional Shinto wedding ceremonies.
The history of Shinkai Sansha Jinja is closely intertwined with the development of Saku City. Based on its enshrined deities and long-standing traditions, the shrine has remained a central focus of local faith. The grounds are a place where seasonal rituals and specific life-event prayers are still practiced today, ensuring that ancient Japanese customs and cultural connections are preserved and passed down through generations.

The shrine grounds offer a serene and tranquil environment perfect for prayer and reflection. The area is well-maintained with clear paths, allowing visitors to explore the various sections of the shrine grounds and appreciate the architectural layout. During specific seasons when annual festivals or local celebrations take place, the atmosphere becomes particularly vibrant and unique.
While the shrine grounds are accessible, formal prayer services and ceremonies are primarily conducted during the reception hours of 9:00 AM to 4:00 PM. Visiting during seasons when Shichi-Go-San or other traditional annual events are held provides a deeper insight into local customs. We recommend visiting during daylight hours to fully appreciate the peaceful atmosphere and the details of the shrine architecture.

Shinkai Sansha Jinja hosts a wide variety of formal prayers (Gokigan) and rituals. Please note that many of these require prior consultation or a reservation via telephone:
Most ceremonies are performed at the Haiden (offering hall). Additionally, Shinto priests can perform rituals at external locations, such as ground-breaking ceremonies or tree-clearing rituals, upon request.
The shrine is surrounded by the beautiful natural landscapes characteristic of Saku City. We recommend checking local information or official websites in advance to plan your visit to the surrounding area and enjoy the local scenery.
