Choshizuka Tumulus is a keyhole-shaped Tumulus built in the former part of the Tumulus period (around the late 4th century). It has a total length of 169m and it is one of the largest of the burial mounds built in the same period in Eastern Japan.
Excavations revealed haniwa (clay image) lined up in the mound. Moreover, burial goods such as bronze mirrors, comma-shaped beads, a cylindrical bead, single-edged iron swords and double-edged iron swords, were discovered from the pit-style stone chamber in the rear part of the tomb.
Now some of these goods can be seen at the Museum of Archaeology.
