頭川神社, Shinto shrine in Japan

Todzukawa Shrine is a village shrine (mura-ji) of the Zukawa district in Takaoka, Toyama Prefecture. Its site is thought to have been a small castle or fort, part of the Hōdatsu hills that run along the old border between Kaga and Etchū provinces. The shrine is said to have enshrined the tutelary deity of such a fort's lord and his family.

The shrine is believed to date to the Sengoku or Edo period, though exact origins remain unclear from available records. The surrounding landscape shows signs of former fortifications or castle structures, suggesting the site held strategic importance in its past.

The shrine is the village shrine (sonsha) of the Zukawa district, and its grounds are thought to occupy the site of an old fort or castle. The surrounding Kuniyoshi area preserves many castle sites, and local folklore links them to tales of buried treasure, a giant serpent, and a salt merchant turned to stone by divine punishment.

The shrine is open year-round for public visitation without special requirements or restrictions. Nearby bus stops and road access make it convenient to reach, though visitors should observe respectful conduct when on the grounds.

Local legend speaks of a conflict between two princesses that unfolded in this area long ago, a story connected to the site's suspected past as a defensive stronghold. A tunnel nearby is known for supernatural rumors, though these stories typically exceed what actually occurs.
