The is a series of mountain ranges in Japan which bisect the main island of Honshu. The peaks that tower over central Honshu have long been the object of veneration and pilgrimage. These mountains had long been exploited by local people for raw materials, including timber, fuel, fertilizer, fodder, meat, minerals, and medicines. Most visitors came to the mountain for pilgrimage, especially to the Buddhist temple and the sacred peak of Mount Tate. The name was coined by English archaeologist William Gowland, and later popularized by Reverend Walter Weston (1861–1940), an English missionary for whom a memorial plaque is located at Kamikōchi, a tourist destination known for its alpine climate. When Gowland coined the phrase, he was only referring to the Hida Mountains, but it now also applies to the Kiso Mountains and Akaishi Mountains. History The Japanese Alps has a long history before William Gowland established this name. The Japanese Alps have been used as a place of ascetic practice for Buddhists monks and Shugenja since ancient times. From the 1600s to the 1800s, samurai officers of the Kaga domain travelled deep into the Hida Mountains with local hunters and farmers as guides to preserve the timber of the mountains and continued to create maps recording ridges, valleys and vegetation. This survey is called Okuyama-mawari (奥山廻り). Even now, it is very difficult to cross the steep Hida mountains, one of the world's heaviest snowfall areas, in winter. Therefore, it is considered a historical event in Japan that in the winter of 1584, daimyō Sassa Narimasa's forces crossed over the mountain range over Zara Pass and Harinoki Pass. This event is called "Sarasara-goe" (さらさら越え) derived from Sassa and Zara Pass. However, these Hida Mountains surveys did not seem to have been inherited by modern Japanese mountaineers who trekked through the mountains as a sport. As Kojima Usui later recalled, “in those days,... no one knew even the names of the mountains, much less their locations or elevations. To go mountaineering was literally to strike out into the unknown country.” The first modern geological survey sheets were issued in 1890. The report mentioned major peaks, but the topography was mostly guesswork. From 1891, foreign travelers were able to find useful information in Basil Hall Chamberlain and W. B. Mason's Handbook for Travellers in Japan. However, for decades, the Japanese were climbing these mountains without a comparable guidebook. Japanese people did physical
