Mutsu Bay
It is bordered by the Pacific Ocean to the east, Tsugaru Strait to the north and Mutsu Bay to the west and south. Shaped like an axe pointing west, the peninsula has a thin "axe handle" connecting the mountainous "axe blade" to the mainland of Honshū to the south. The peninsula contains the northernmost point on Honshū, Cape Ōma, and the largest sand dunes in Japan (the Sarugamori Sand Dunes).
