Ishouzuka Kofun

Ishouzuka Kofun is a large burial mound in Unomowari-machi, Kakamigahara, Gifu Prefecture, Japan. It forms part of the Unomowari-machi Kofun Group and has been designated a Gifu Prefecture Historic Site since 25 March 1957.

The mound is broadly circular, measuring 52 metres across and 7 metres high, making it the largest round kofun in Gifu Prefecture. Its eastern, western, and southern edges have been cut down, while the northern side retains its original form. The slightly projecting southwest section suggests that it may originally have been a keyhole-shaped mound facing west, with the front portion removed during land development at nearby Kūan-ji.

No excavation has been carried out, so its burial facilities and grave goods are unknown. No stone facing or haniwa clay figures have been identified on the mound’s surface. It is dated by its form to the later fourth century or around the end of the fourth to early fifth century CE, within the broader 250–650 CE period of kofun construction.

Ishouzuka Kofun is generally considered part of a related group of early and middle-period mounds in the Kakamigahara area, alongside Ichimaruyama Kofun, Bō no Tsuka Kofun, and Kane Nawazuka Kofun. Ichimaruyama Kofun once stood about 50 metres to the southeast but has disappeared, while another late-period mound in the Unomowari-machi group has also been lost.

Ishouzuka Kofun is a megalithic mound (tumulus with integral stones) in Japan. A typological estimate: 250 CE to 650 CE. No English Wikipedia article exists for it; the full text below is the Japanese article "衣裳塚古墳", shown in the original language.
