Satellite tomb Otsu (No. 2, 62m round mound) of Daisen Kofun. 5th century. Together with the Chayama satellite (No. Kou), it forms part of the eastern satellite cluster of Daisen Kofun. The name "Daianzi" recalls a Buddhist temple once located here, a remnant of the historical coexistence of ancient burial mounds and early Buddhist facilities.Constituent monument of the "Mozu-Furuichi Kofun Group" UNESCO WHS (2019). The building of Buddhist temples atop or adjacent to kofun is seen throughout Japan, reflecting a cultural continuity in which ancient sacred hilltops were reappropriated. Daianzi Kofun exemplifies this layering of ancient burial practice and later Buddhist faith.

Satellite tomb Otsu (No. 2) of Daisen Kofun. A round mound, 62m diameter. 5th century. Slightly larger than the Chayama satellite (56m). The name "Daianzi" derives from "Dainaji Temple," a Buddhist temple once located near or on the mound—a phenomenon seen nationwide in the late Kofun and Nara periods when Buddhist facilities were often built atop or adjacent to ancient burial mounds.
