Mount Daisengen (大千軒岳, Daisengen-dake) is a 1,072-metre (3,517 ft) mountain located on the Oshima Peninsula of Hokkaidō, Japan. Mount Daisengen is the tallest mountain in the southern region of the peninsula.^[1]

A gold mine was established on the mountain during the Edo period, and a group of 106 Japanese Christians were executed on the mountain^[2] by the Matsumae clan during the nationwide crackdown on Christianity.

Several climbing routes exist.

History

By about 1612, some Japanese Christians began to flee to the less populated Tōhoku and Ezo (modern-day Hokkaido) regions of Japan in order to escape religious persecution by the Tokugawa shogunate.^[3] Some of these Japanese Christians took up residence working at the gold mine near Mount Daisengen.

The aftermath of the 1637 to 1638 Shimabara Rebellion led to a more severe government crackdown on Christianity within Japan, and in 1639, the Matsumae clan executed 106 Japanese Christians who worked on the mountain mining gold.^[3]
