Omaezaki City lies approximately 80 miles (130 km) south of Shizuoka City at the tip of a peninsula of the same name, stretching east into the Pacific Ocean. The majority of the city consists of gentle hills and valleys with some steep cliffs on the peninsula's east coast. Like much of Japan, Shizuoka Prefecture is an earthquake zone, and small tremors frequently occur in the area. Omaezaki is also in an area at risk from tsunami.
