In 1894, the country was a powder keg. The explosive potential lay in a wild profusion of mountains to climb, a rising class of energetic young men with money to burn, and new railways that could carry the men to the mountains. In short, Japan was primed for the outbreak of modern mountaineering. Except that, so far, nobody had thought of becoming a mountaineer.
Strange to say, this volatile mixture was touched off by a writer who probably never climbed a mountain in his life. As for the match he used to light the blue touchpaper, it was a treatise that went by the less than incendiary title of "Theory of the Japanese Landscape" (Nihon Fūkeiron). Yet, within a few years, it was this book that inspired Japan's first attempt at modern mountain exploration.

In 1880, Shiga moved on to the Sapporo Agricultural College, the forerunner of today's Hokkaidō University. The college had been founded with American help and classes were taught in English up to 1882. While polishing his language proficiency, Shiga steeped himself in contemporary ideas. Darwin became a strong influence on his own thinking.
Sapporo graduates were trained to become the nation's elite - "Boys be ambitious!" they were told by the college's founder, William Smith Clark. Alas, the jobs on offer when they graduated didn't necessarily match up to expectations. Shiga became a botany teacher at a junior high school in Nagano. This job imploded, as did the prospect of any further employment nearby, when in a fit of frustration he insulted the prefectural governor.
Shiga's big break came in 1886, when he persuaded the Imperial Navy to let him join a training cruise to the South Pacific. Actually, the Navy turned him down at first, only relenting when Shiga reminded them how the British navy had invited Darwin on the voyage of the Beagle. (This parallel must have meant something to Shiga; when he later discovered that an HMS Beagle had been sold to Japan, he tracked down the ship. Salvaging a small piece of timber, he installed it in a place of honour in his tea-house in Yokohama.)
If the Navy had taken a bet on Shiga, it was swiftly rewarded. Within a few weeks after landing back in Japan, the writer published Nanyō Jiji, a best-selling account of his voyage on board the screw sloop Tsukuba. For Shiga, it had been a formative journey: the ship had visited the Caroline Islands, Fiji, Samoa, Hawaii, Australia and New Zealand - all either colonised by western powers or otherwise under their sway.
Colonialism was not all bad. Shiga was impressed by the British administration in Australia, and again by the ethos of hard work and sacrifice that he sensed in New Zealand. At the same time, he was horrified by the plight of the native peoples. The Darwinistic implications were clear: backward cultures would be subjugated by those from more advanced civilisations.
After his meeting with a Maori chief, Wi Tako, Shiga wrote: "Alas! Japan could become another New Zealand. As I look up at the autumn skies of these Southern Seas, I fear the threat to my home country far away. Having witnessed such cultural and racial oppression in New Zealand, I - as a son of the new Japan - must take immediate action to make my people aware of this possibly happening back home." (Nanyō Jiji)
Back home, Shiga became the editor of Nihonjin, a magazine established in 1888 to restore national self-confidence. In the very first issues, Shiga launched on the theme that he would later develop in Nihon Fūkeiron - the relationship of the Japanese people with the land of Japan. In the second edition, he wrote:-
The influence of all environmental factors of Japan - her climate and her weather conditions, her temperature and humidity, the nature of her soil, the configuration of her land and water, her animal and plant life and her landscape, as well as the interaction of all these factors, the habits and customs, the experiences, the history and development of thousands of years - the totality of these factors has gradually, imperceptibly, developed in the Japanese race inhabiting this environment a unique kokusui (national essence).

Landscape into kokusui: that pretty much sums up the essence of Nihon Fūkeiron. The theme is fully worked out in Shiga's masterpiece. Take, for example, this description of pine trees in the mountains:-
Standing against fierce winds, they distinguish themselves from other trees. What a graceful picture they present . Their trunks, branches, twigs and leaves defy all gusts of wind. Even after other feeble trees wither, they still remain alive. If they happen to be cut by an axe, they fall to the ground triumphantly, in a manner no other trees can display. Thus, Japanese pine trees typify the characteristics of our fellow countrymen. (Nihon Fūkeiron)
According to Shiga, such pine trees exemplify "tettō" - unspoiled wilderness scenery - one of the three qualities that distinguish Japan’s landscapes. The other two characteristics are "shōsha" (elegance), best exemplified by the autumnal beauty of Japan's maples, and "bi" (beauty), as seen in the nightingales and blossoms of spring.
Shiga grounds his aesthetics in geographical fact: Japan owes its magnificent forests and flora to its enormous climatic variation, from sub-tropical to sub-arctic; its high humidity imbues the landscape with a special hue; heavy rainfall sculpts its landforms into intriguing crags and gorges; and, above all, the country has volcanoes.
Shiga was lucky with his timing, getting Nihon Fūkeiron to press just after the start of Japan's war with China. Readers were in the right mood to be compared to storm-defying pine trees. Within eight years, Nihon Fūkeiron was reprinted fifteen times. So many copies rolled off the presses that you can still easily and cheaply pick up early editions in the bookstores of Kanda.

Start out; ascending about eight hours from the village of Shimashima, you will reach the hut on the Tokugō pass at about 1,500 metres in altitude; from there, in about three leagues, you will find the Miyagawa hut, which you can regard as the foot of the mountain proper; from Miyagawa, climb six leagues or seven hours, and you will reach the summit; for the first three of these hours, you will follow a fast-flowing river that cuts through granite walls; mountains made of granite rise skywards one above the other; as you leave the river, the mountains become still more precipitous, the view more and more impressive, the granite presenting its mysterious forms as if it were a huge landscape painting; as you continue, you will step onto snow, and sometimes you will see ptarmigans, bears, and mountain goats (kamoshika); if you want to know the real nature of granite mountains, then you must by all means climb Yarigatake.
It matters little that Shiga probably cribbed much of this appendix from the English-language Handbook for Travellers in Central and Northern Japan, published by Ernest Satow and A G S Hawes a decade or so earlier. Nor that the Japanese author had scant personal knowledge of mountain-climbing. For the effect on Kojima was electric; on reading the passage about Yari, as he later recorded, he felt "as if his heart and soul had been blown away".
Getting to the mountain took a little longer: his parents were opposed, accurate maps didn't exist and - most vexing of all for the prototype salaryman-alpinist - he could take barely a fortnight's annual leave from his bank. Nevertheless, after one false start, Kojima reached Yari's summit in 1902, together with his friend Okano Kinjirō, an oil company employee.

Arguably, Yarigatake Tankenki (Exploring Yarigatake) was Japan's first work of modern mountaineering literature. Or perhaps Japan's first work of modern mountaineering literature in Japanese. For, when he published it, Kojima was still completely unaware that an English mountaineering missionary had preceded him to the summit of Yari eleven years earlier.
Walter Weston had written up his climb in Mountaineering and Exploration in the Japanese Alps, published in London in 1896. But the book was hardly known in Japan at that time - it wasn't until later that it was translated.
So it was only by chance, in the summer of 1903, that Okano Kinjirō, the Standard Oil man, saw a copy of Weston's book at a colleague's house and learned of the author's climbing activities in the previous decade. Then he discovered that, in the meantime, Weston had returned to Japan and was now living close by, in Yokohama.
An invitation to tea with the Englishman soon followed. Weston showed Kojima and Okano an alpenstock and other pieces of equipment, as well as several issues of the Alpine Journal, the year book of Britain's long-established Alpine Club. Okano was much taken with the kit; for Kojima, however, it was the idea of a club that took hold. Two years later, in late 1905, he and a small group of friends formed their own "Mountain Club" - known at first simply as the "Sangaku-kai" after its model.

One of the earliest acts of the new Japan Alpine Club was to elect Walter Weston as its first honorary member and vice chairman (right in picture) and Shiga Shigetaka (left in picture) as its second. Yet, by Kojima's own account, the priority could well have been reversed. As far as he was concerned, the birthplace of the Sangaku-kai was Yarigatake. “Thanks to that climb,” he continued, “I got to know Weston, from whom I learned that there were alpine clubs all over the world. Before that, nobody had ever suggested to me the idea of a club. But, as to why I climbed Yari in the first place, that was because I’d been inspired by a book – none other than that of the late Shiga Shigetaka-sensei. We are all obliged to this great instigator.”
