ABOUT
About Onjuku Town
Onjuku Town in Isumi District attained town status in 1914 and took its present shape through a merger in 1955. It is known as the setting of the children’s song “Tsuki no Sabaku” (The Desert under the Moon), as one of Japan’s three major areas of ama divers, and for a historic site marking the 1609 rescue of a Spanish ship that drifted ashore. The town office is in Suga.
