Mount Daisengen (大千軒岳, Daisengen-dake) is a 10720NaN0 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.
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.
