Perched on the roots of a mountain birch, we ate our cheese butties and looked down on the wooded col. The dappled sunlight filtered through the trees, suggesting to us a sylvan idyll - until we noticed, scattered among the weeds, the rusting tins, empty gas cartridges, and shreds of tent fabric that hinted at desperate struggles against the elements. This col, we sensed, could be a happening place.


That forced a change of plan. Moving to Tokyo, he joined the famous Tosho-keiryūkai club and passed the entrance exam for Tokyo Agricultural University, already a hotbed of mountaineering activity.
Now began the heyday of Matsunami's career. While some top climbers specialise in a particular cliff or region, he was everywhere, putting up new routes on Tanigawa, on Yatsugatake and in the Southern Japan Alps. The first winter ascent of No 1 Ridge (topo below) in Takidani in February 1939 was a milestone in the advancement of Japan's alpine climbing standards.


As if the route's length and technical difficulties were not enough, Matsunami and Arimoto decided to do without pre-placed dumps of food and fuel. Nor would they call on support parties, as was common practice for winter expeditions. That meant they'd have to carry twenty days' food and fuel on their own backs, as well as all their climbing and camping gear.

When Arimoto came up to Yumata, the climbers decided to leave the tent behind; it was now too heavy to carry. Instead, they would dig snowholes or huddle under a flysheet ("zelt"). This was a fateful decision. On December 30, they crossed the suspension bridge at Yumata, heading for the Kitakama. The next day, they made their first bivouac on the ridge, shivering under the flysheet as it was lashed by hail and sleet. It was the worst night out that either had yet experienced.
On New Year's Day, the storm strengthened into a full blizzard, piling a foot of new snow onto an icy crust. Neither crampons nor snowshoes would work in this pother, but the pair made it as far as Kitakama col - where we were now sitting - into which they dug a snowhole. Then they did their best to dry out their sodden clothes over the roaring stove, until it started sputtering and misbehaving.
The storm pinned them in their snowhole for the whole of the next day. Until Matsunami could fix the stove, they had to burn petrol in an open can to stay warm and melt snow. Soot blackened the walls of the snowhole, but their clothes stayed sodden. Now they had to decide whether to go on or go down. Just at this critical juncture, the climbers looked out of their snowhole and saw a starry sky. Then Matsunami managed to jury-rig the stove.

It was on this afternoon, in hindsight, that the jaws of the trap sprang shut. In the snowhole that evening, Arimoto discovered that he had second-degree frostbite to his feet. Later, the gale blew in the door of their shelter, covering the climbers with spindrift and soaking and freezing them anew.
With retreat to the north blocked by the bulk of the Doppyō, the climbers decided to jettison as much gear as possible - these would be the telltale relics found by the search party - and stake their lives on a dash towards Yari. But when they struggled out of the remains of the snowhole into the relentless blizzard, they found the straps of their crampons frozen into a solid tangle.
Without crampons, they were forced to start step-cutting their way along the icy flanks of the ridge. Blinded by the buffeting gusts of spindrift, Arimoto slipped and fell into a gully on the western side of the ridge. As he was too exhausted to climb back, Matsunami went down to join him. Unable to regain the ridge, they forced a way downwards through chest-deep snowdrifts. At 3pm, they dug another snowhole.
On January 6th, the blizzard still raging, Matsunami begins to sense there is no way out. His whole body is freezing; he's at the end of his strength. Arimoto can no longer move. Somehow, he himself could probably get down to Yumata, but that would mean leaving Arimoto alone. He can't do that, so he decides to stay and die. It is six o clock when he makes the decision to die with Arimoto, he records.
"Mother," he writes in his diary, scribbling with a pencil stub gripped in frost-bitten fingers, "thank you for your love - I'm about to join my father. We can't do anything more. Please forgive me. Ask Inoue-san to fix everything." He writes to Inoue, and puts in a note to other friends too: "Arakawa-san - sorry I couldn't return the sleeping bag."

And then: "We die, we dissolve into water, we flow into the sea, we feed the fish, then we become some body again; we just borrow our shape and go round for ever. Matsunami." He stops writing and wraps the diary in a waterproof pouch, and that is where the search party finds it, next to his camera, six months later.
We allowed ourselves ten minutes on that greenwood col. Then Donald nodded at the cumulus clouds that were starting to boil off nearby ridges: "We'd better get a move on," he said. I bolted down the remains of my cheese butty, got to my feet and swung the faded army-green pack to my shoulders. Yes, we'd better get going. We knew little of the Kitakama's illustrious history, but the scattered gear in front of us told its own story. We didn't want to spend the night out on this ridge.
