Miyazuka Kofun

Miyazuka Kofun is a burial mound with a square base and domed top located in the Hirose district of Kumagaya. The structure exemplifies the funerary architecture built during the Kofun period in Japan.

This burial mound was constructed in the second half of the 7th century as part of the Hirose tumulus cluster along the Arakawa River. It represents a period when elite members of society were interred in such stone structures.

The mound originally displayed fukiishi decorative stones, reflecting burial practices of elite individuals during the final phase of the Kofun period in Japan.

The site is reachable on foot from Hirose-Yacho-no-Mori Station on the Chichibu Railway line. Checking public transit options and walking routes in advance makes planning your visit easier.

The burial chamber has never been explored by archaeologists, leaving its contents and internal structure a mystery to this day. This undisturbed state may preserve secrets from the 7th century.
