Temiya Cave

Temiya Cave is a natural tufa cave marked by ancient engravings and paintings from the Zoku-Joumon period etched into its stone walls. The site has been enclosed within a protective building that houses both the original cave and an educational museum.

An Imperial Guard soldier discovered the cave in 1866 while building a herring watch post. This chance discovery revealed prehistoric markings that now contribute to our understanding of early human activity in the region.

The engravings show patterns and marks that visitors can see today, raising questions about the intentions of those who created them. Scholars debate whether these signs represent pictures, symbols, or an early form of written language.

The cave is housed in a building typically open from May to October for visitors to view the engravings. Check locally beforehand, as access and hours may vary seasonally and the site is protected.

The cave formed naturally and bears markings whose exact age and purpose remain subjects of debate among experts. This mystery makes it engaging for visitors to form their own theories about the ancient marks.
