Karinba Ruins (Eniwa City) are located about 800 meters north of JR Eniwa Station. The ruins are recognized as a graveyard used by ancient people living here about 3000 years ago. In 1999, when a new road was being constructed for a redevelopment project in front of the station, the ruins were discovered by chance. Some accessories such as lacquered combs, hair ornaments, earrings, bracelets, and decorative straps for a person’s waist were retrieved from the ruins. It was the first time lacquered ornaments used by ancient people in Japan were found.
