Overview

An early mound at Ama Goshono-cho in Takatsuki. Takatsuki City publications variously date it to the mid or late 3rd century. Its Seiryu 3 mirror is famous, but whether it was among those presented to Himiko is unproven.

Finds & research

Finds include five bronze mirrors, glass beads, and iron weapons and tools. One is a TLV-type mirror inscribed Seiryu 3 (235), and two are triangular-rimmed mirrors with four deities and four beasts. The assemblage is an Important Cultural Property.

Two views on the occupant

Archaeological view
A rectangular mound measuring 18m east–west by 21m north–south on the middle slope of Mount Ama. The central wooden coffin yielded five bronze mirrors, glass beads, and iron weapons and tools. Only one mirror, a TLV-type mirror, bears the inscription Seiryu 3 (235).
Imperial Household Agency view
This is not an Imperial Household Agency mausoleum. The mound itself is not a National Historic Site, but its assemblage of finds is designated an Important Cultural Property. Takatsuki City has reconstructed and opened it as Seiryu Sannen no Oka.

Field notes

The reconstructed mound is open free of charge within Takatsuki Municipal Cemetery. Follow the cemetery's current opening information.
