Ojigahama Beach is about 4 km long and is made from gravel deposited from the mouth of the Kumano-gawa River. It is also known as a loggerhead turtle spawning ground.

From Onigajo, Shichirimihama continues about 22 km to the mouth of the Kumanogawa River, making it Japan’s longest gravel beach. The unique scenery incorporating the majestic Kumano-nada Sea, the sandy beach and rows of pine trees is a highlight. Caution is required when walking along the beach as the waves of the Pacific Ocean strike hard when they break on the beach and the current is strong.
