Mount Udo

A hilly mountain in Shizuoka City. It is 307 meters above sea level. It is also called "Udosan." The mountain is made up of the sand and gravel layers of the Abe River and marine mud layers that were deposited in the Pleistocene (Pleistocene) Epoch, and was formed by a dome-shaped uplift movement. Facing Suruga Bay to the south and Shimizu Port to the east, it has steep sea cliffs, but the north and west sides have wide flat areas that form a plateau where tea plantations are distributed. The eastern slope is used for cultivating mandarin oranges, and the area from the bottom of the sea cliffs to the beach in the south is used for cultivating strawberries. The flat area near the summit is called Nihon-daira, and the view of Mt. Fuji is magnificent. Toshogu Shrine on Mount Kuno, located south of the summit, is a famous tourist destination, along with the Toro ruins and Miho no Matsubara. Nihon-daira Zoo is located on the western foot of the mountain.

静岡市にある丘陵性の山。標高307メートル。「うどさん」ともいう。山地は更新世（洪積世）に堆積(たいせき)したかつての安倍(あべ)川の砂礫(されき)層や、海成の泥層からなり、ドーム状隆起運動によって形成された。南は駿河(するが)湾、東は清水港の海に面して海食崖(がい)の急斜面をもつが、北と西側は広い平坦(へいたん)面が残って台地状の地形となり茶園が分布する。東斜面はミカン、南の海食崖下から海浜にかけてはイチゴの栽培地である。山頂付近の平坦面は日本平(だいら)とよばれ、富士の眺望は絶景である。山頂南方の久能山(くのうざん)の東照宮は、登呂(とろ)遺跡、三保松原(みほのまつばら)とともに観光地で名高い。西麓(せいろく)には日本平動物園がある。
