The Beppu-Bucht ( Japanese 別 府 湾 , Beppu-wan ), formerly also called Kantan-Bucht ( 菡萏 湾 , Kantan-wan , Eng. "Lotosbucht") after its shape reminiscent of a blooming lotus flower , is a bay of the Seto -Inland Sea in the east of the Japanese island of Kyūshū .

Beppu Bay separates the Kunisaki Peninsula in the north from the Saganoseki Peninsula in the south. To the east of the bay, the Iyo-nada marine region joins the Seto Inland Sea. The 475 km² bay has an average water depth of 36 m and measures 70 m at its deepest point. In the north-west of the bay is Morie Bay ( 守 江湾 , Morie-wan ; 33 ° 24 ′ 24 ″  N , 131 ° 39 ′ 23 ″  E ), also called Kitsuki Bay ( 杵 築 湾 , Kitsuki-wan ). Important tributaries include a. the two rivers of the first order Ōno-gawa and Ōita-gawa , which flow into the south of the bay.

Geologically, it is believed that the bay is a U-shaped rift valley or caldera .

Along the bay communities extend counterclockwise Kitsuki , Hiji , Beppu and Oita of Oita Prefecture .

Uryu-jima

According to historical sources, the island Uryū-jima ( 瓜 生 島 ) with a circumference of 12 km was located in the southern part of the bay about 500 m from Ōita . This is said to have flooded the bay with a 4 m high tsunami during the earthquake of September 4, 1596 , and finally sank. However, topographical studies of the sea floor have so far not provided any indications of their existence.
