In April-June, 1968-70, constructions of four burrows of <I>Vulpes vulpes japonica</I> GRAY, 1868 dug in fields covered by small bamboo, bracken and weeds, were examined at Yabe-Machi, Kumamoto Pref., Kyushu, Japan. From the entrance which measured 20-30 cm. in diameter, the burrow descended to a depth of 50-100 cm. and then extended horizontally forming a labyrinth of passages and blind alleys. Two of the burrows were being used for breeding and had more complicated constructions than others. In these burrows, remains of food and excrements were scattered everywhere and at several spots leaves of trees and grasses were gathered, mixed with remains of food and excrements, in an area of about 30x20 cm., with a thickness of 1-2 cm.
