Various traditions exist as to the origin of the name, one being that when Minamoto no Yoshitsune's pet dog Wakamaru was left behind on the peninsula, he howled for seven days and nights.
Another explanation is that the region was home to numerous Japanese sea lions, whose barking voice resembles that of a dog.
The cape forms the easternmost point in Chiba Prefecture, close to the mouth of the Tone River.
Markers related to the poems of Shōwa period author Kyoshi Takahama (1874 – 1959) and Naturalist tanka poet Bokusui Wakayama (1885 – 1928) are on the cape.
