Kaitenzan Tomb - Kaitenyama Tomb

Japanese: 快天山古墳 - かいてんやまこふん

This keyhole-shaped tumulus is located in Kurikuma Higashi, Ayauta-cho, Ayauta-gun, Kagawa Prefecture. It was built facing northeast at the southern end of the Yokoyama mountain range, overlooking the plains of central Sanuki to the west. It is 100m long and has a diameter of 65m at the rear mound. However, the location of the end of the front mound is unclear. It is furnished with roofing stones and haniwa clay figures. In 1950 and 1951, three split-bamboo shaped stone coffins were excavated from the rear mound. Each sarcophagus has a built-in stone pillow. A Chinese-made square grid mirror, beads, stone bracelets, swords, iron arrowheads and agricultural tools were excavated from Sarcophagus No. 1, which was covered with a pit-type stone chamber-like facility, while an imitation mirror with an inner floral pattern, tubular beads, swords, axes and knives were excavated from Sarcophagus No. 2, which was covered with clay and stone slabs, and an imitation mirror with an inner floral pattern, swords and iron arrowheads were excavated from Sarcophagus No. 3, which was covered with clay, and a jar-shaped pottery was also excavated from outside the coffin.
