exploration over a decade in the 1890s. They divided the mountains into (north, central, and south) depending on how they were conventionally grouped. William Gowland, an English geologist, first thought of this swath of terrain as forming a single coherent landscape, comparable to the European Alps. Gowland's view was further developed by another Englishman and Christian missionary, Walter Weston, who was able “to canonize Gowland's geographical conception, deploying it as a de facto proper noun”. Gowland explored several parts of the ranges in the 1860s, being the first documented foreigner to climb two peaks in the Alps, Mount Yari and Mount Norikura. Gowland was an archaeologist, and he explored these ranges for archaeological reasons. While Gowland was the first foreigner to explore the ranges, Reverend Walter Weston, a Christian missionary, was the first foreigner to document his experiences. About twenty years after Gowland's explorations, Weston explored the ranges himself with Gowland's notes on his explorations. Weston was led up many mountains by Kamijō kamonji, a mountain guide living in Kamikōchi. Weston not only explored the same ranges that Gowland previously traversed, but also ascended the Mount Shirouma, Mount Jōnen, Mount Kasa, Mount Hotaka, and other minor mountains. Weston first documented the two main mountain systems distinguishable by geological structure. The first of these he called the "China system" due to its connection with southeast China from just south of the Japanese archipelago. The second was called the "Karafuto system", due to the fact that it enters Japan from Karafuto to the north and runs southwest. These two were considered to be the first western explorers of the range, and as a result Weston, with the help of Gowland, popularized and documented different parts of the ranges in an incredibly in-depth manner for others to expand on. In 1907, Yoshitaro Shibasaki and others succeeded in climbing Mount Tsurugi, which is said to be the last unexplored peak in Japan and the most difficult to climb. On this occasion, they found the ornaments of a metal shugenja'''s cane and the sword on the top of the mountain, and a scientific investigation later confirmed that the ornaments of the cane and the sword were from the late Nara period to the early Heian period. It turned out that Mount Tsurugi had already been climbed by shugenja'' more than 1000 years ago. From the 1960s to the 1970s, the transportation infrastructure of the Japanese
