Hakusan jinja

A Shrine Preserving Pre-Sengoku Styles
Hakusan Shrine is located deep in Iiyama, in the mountainous Kunugawa district. Situated near JR Iiyama Line and a local elementary school, the shrine is hidden in the mountains, making it difficult to see. The prominent Nadate Shrine beside the school is more noticeable.

The shrine's main hall is a kasuga-zukuri style structure, approximately 2 shaku wide. The well-preserved details indicate it has been protected by its covering shed since the Ōei era. The lack of later architectural developments, such as bracket arm expansion, suggests an ancient style.

Unique features include a forward-projecting bracket supporting the roof beam, which became a common style in Nagano. The intricate carvings on the rafters and the decorative shachihoko at the beam ends reflect significant ornamental advancement.
