A distinctive rock shelf born of wave erosion, spreading right beside Aoshima Beach (青島海水浴場). The name comes from how the layers of plate-like rock resemble a washboard, and it is designated a national natural monument and place of scenic beauty. You can also enjoy the view from Yayoi Bridge (弥生橋) on the approach leading to Aoshima Shrine (青島神社), and at low tide the expanse of rock appears even larger. Some footing is slippery, so strolling in sandals is recommended. Before sea bathing, start by observing this mysterious landscape created by nature together as a family.
Tips
It is located right by Aoshima Beach (青島海水浴場) and can be viewed along the approach to Aoshima Shrine (青島神社). The rocks are slippery when wet, so holding small children's hands is reassuring. Checking the low tide times in advance lets you see a wider stretch of the rock shelf.
Best time to visit
About 45 minutes. The morning, when the sunlight is soft, suits strolling
