Shizuoka Prefecture 賀茂郡A sea that declared itself Japan's finest sunset.
Suruga Bay sunsets01 ／ Sea cave
Tensodo (天窓洞) at Dogashima is a cave the sea carved out of white rock. Halfway along its 147 metres the roof has fallen in, leaving a round skylight, and light comes in so sightseeing boats can sail right inside. It is designated a natural monument. The Dogashima bus stop is a one-minute walk away.
02 ／ Island
At low tide Sanshiro Island (三四郎島), off Sehama, is joined to the shore by a stone path about 30 metres wide, and you can walk across (a tombolo). The island keeps a legend of a young warrior hiding from the Taira and a girl named Koyuki who loved him.
03 ／ Sunset
The cliffs of Koganezaki (黄金崎) are weathered andesite turned yellow-brown, and they shine gold in the evening sun. They became a prefectural natural monument in 1988. Proud of sunsets such as the one at Otago Beach (大田子海岸), the town declared itself Japan's finest sunset (夕陽日本一宣言) on 23 September 2005.
Living here
There is no railway in town. A Tokai Bus from Shuzenji Station takes about 1 hour 15 minutes, and about 2 hours from Mishima. From north to south, the harbour towns of Ugusu, Arari, Tago and Nishina line the Suruga Bay coast, and the town hall is in Nishina. The present town was formed in 2005 by merging with Kamo Village.
