  Sugiyama took the copy of the map from his backpack and entered a rough estimate of their current position. He also took a photograph of the surrounding landscape so they would be able to locate this place again in the future.

  Not surprisingly unaware of Sugiyama’s dilemma, Sakakibara was attempting to squeeze his hefty frame through the opening.

  It was clear that he fully intended to enter the limestone grotto. They were wearing cotton overalls and had some caving equipment in their backpacks, although not the gear they would need on a serious spelunking mission.

  Sugiyama tugged at Sakakibara’s overalls and tried to pull him back.

  ‘Don’t you think we’d better leave that until later?’

  Their journey around the mountainside on that particular day had been meant simply for discovering underground caves, not actual exploration. Sugiyama tried to convey his concern that they had been lucky enough even to find a suitable cave, and that they should now be returning. Yet he did not have the physical strength to pull Sakakibara back. Neither could there be any denying that he was also very intrigued as to what might be inside.

  ‘There’s no going back now!’

  Sakakibara’s tone was aggressive as he wriggled about to shake off Sugiyama’s hand. Sugiyama angrily called to him and stood there tut-tutting in consternation. Yet he also felt something snap inside and found that he was reasoning with himself: As long as we don’t get trapped anywhere deep. As long as we just take a quick look inside. As long as we content ourselves with just that – nothing could possibly happen then.

  For ten meters or so into the cave, there was only enough room to crawl forward in single file. In the light of his headlamp, Sugiyama could see Sakakibara’s rump ahead dancing side to side as he crawled forward after him. In fact, Sakakibara’s rump blocked the whole tunnel, making it impossible to see ahead. Sugiyama couldn’t imagine how a man of Sakakibara’s build could ever have become a spelunker. Nor could he imagine whether it had been a good idea to invite Sakakibara on this mountain hike. There was something reckless about him, and recklessness could cost lives.

  Sugiyama had known Sakakibara for no more than three years. He had met Sakakibara after joining the Pilot Caving Club in Hachioji. As a member of the Explorers’ Club at college, Sugiyama had taken an active interest in both mountain climbing and marine sports, devoting his youthful energies to rock climbing and scuba diving. With increasingly less time and money to spend on adventure sports once he started working, he had focused on caving as a pursuit endowed with the dual aspects of both land and sea. Rock-climbing techniques were needed to traverse up and down shafts a hundred feet or more in length. Moreover, water was inevitably encountered in caves, given the nature of limestone caves, grottos carved out of limestone by the solvent action of running water. Hence, diving techniques were also required whenever a caving enthusiast wished to explore a current of crystal-clear water that was otherwise impassable. Sugiyama had no sooner taken up caving before he found himself hooked. There was no lack of spelunking sites in Japan, where numerous limestone plateaus could be found. Not only that, but in the mountains not too distant from central Tokyo lay virgin stalactite grottos that could only be described as halls of wonder. Not only was caving an inexpensive hobby, it was also one that fully sated his appetite for adventure.

  The epitome of caving lies not in exploring grottos that have already been discovered by others, but in being the first to set foot on the virgin rock of an undiscovered cavern. There can be no sweeter taste for a spelunker than such a moment. It is said that anyone who has savoured such a moment is destined to be forever addicted to caving.

  As he crawled forward on his belly, Sugiyama couldn’t help wondering if he was actually in an undiscovered cave. This would be the first time for him. He had been avidly studying the maps for months now. He was convinced that all the signs, whether the local geological features, topography, or sinuous course of the rivers, pointed to the presence of an undiscovered grotto in this locale. The previous evening, Sugiyama had been talking about this to Sakakibara on the phone. With the following day being a Sunday, their conversation had turned to arranging a casual mountain trek to search for caves.

  They had set out early that morning, driving for about two hours and parking the car on the side of a woodland road. Several hours had already passed since they had left the car and begun their trek into the mountains. They must have already walked three or four miles from the road. Not in his wildest dreams had Sugiyama imagined that a casual stroll like this would lead to the discovery of a cave. Sugiyama had agreed that, even if they should come across an opening, they would put off going underground until they could organize a fully equipped expedition with other members of the caving club. Sakakibara had humorously intoned the words fully equipped expedition’, as if to suggest with such a grand expression that the likelihood of their ever discovering a virgin grotto was less than zero.

  They found themselves in a cavernous dome that was probably formed by a cave-in. Yet no matter how much they illuminated the ceiling with their lights, the beams lacked the power to reach the top, thus preventing an accurate assessment of how high the ceiling reached. It must have been at least a hundred feet above the floor of the cave. The cavern had opened up at the end of the narrow tunnel, and it was not until they stood that Sugiyama and Sakakibara became aware of its immense size. Upon realizing the vastness of the grotto, they were literally dumbfounded. Although prepared to encounter a dead-end, they now found themselves in an enormous subterranean cavern that surpassed their wildest dreams. Limestone results from the sedimentation of the remains of sea creatures. Therefore, this area of land was at some time in the distant past located at the bottom of the sea. Thrust up from the sea, the earth had become land, later to be covered by woodlands. Water erosion had then formed this gigantic cavern of majestic proportions. Sugiyama stared at the ceiling in blank amazement, not so much at the size of the cavern as at the incredible length of time that it must have taken to form. After an enthralled silence lasting almost a minute, both of them started to speak at once.

  ‘Fantastic!’

  There was no other way to describe it. Without a shadow of doubt, they had discovered one of the largest subterranean limestone caverns ever found in the Kanto region. Little could they have imagined that such a massive chamber existed under the mountains where they had been hiking just moments before. Excitement welled from deep inside to suffuse every pore.

  ‘It’s moments like this that make you realize you’ll never quit caving, right?’ Intoxicated by their good fortune, Sakakibara whistled a cracked tune as he scanned inside the cavern with his flashlight.

  His whistling struck Sugiyama as annoying; it sounded out of place. Usually indifferent to Sakakibara’s discordant whistling, Sugiyama now found that it rankled his nerves so much that he was unable to ignore it.

  Suddenly Sugiyama felt apprehensive. There was always the risk that, negotiating a constricted passage into an expansive cavern, a spelunker would forget the route taken to get there. Sugiyama took out his compass, took a reading, then entered the direction on his diagram. Yet no sooner had he jotted it down than it occurred to him that he was being quite silly. After all, such precautions were only necessary when you intended to go down much deeper. It was far too hazardous for just two people to enter a newly discovered cave with such inadequate equipment. They should be calling it a day and making their way back.

  Nevertheless, Sakakibara had made his way to the edge of the cavern and was shining his flashlight down in search of a route to pursue. He was still whistling. The sound reverberated eerily through the stalactite girded arena.

  ‘Say, Sakakibara, let’s be getting back,’ Sugiyama called out to his partner, who had his shoulders hunched as he peered frantically at the floor.

  Sakakibara finally stopped whistling. ‘Come look at this. There’s a shaft!’ Paying no attention to what Sugiyama had just said, Sakakibara st
ood there with a triumphant air. He looked even less inclined to leave than before.

  On hearing the word ‘shaft’, Sugiyama’s resolve swayed, for he was renowned among the members of the Pilot Caving Club for having the best shaft-scaling skills. Sakakibara and the others were no match.

  Thinking he might as well have a look to gauge the value of the find, he casually made his way over to where Sakakibara was shining his flashlight. In the vast bell-shaped cavern where they found themselves, there appeared little else that promised to lead them any further than the shaft where Sakakibara was directing his flashlight. Hanging down like curtains, the walls of the cavern merged up here and there with stalagmites that extended up from the floor of the cavern. There may well once have been a passageway leading somewhere off the edge of the cavern, but it had undoubtedly been blocked off by debris from the cave-in.

  Making his way to the edge of the shaft where Sakakibara eagerly awaited him, Sugiyama peered down. The shaft slanted slightly rather than descend at a perpendicular. He could also see that the furthest extremity formed a gentle curve. As shafts went, it was not that deep, and could be negotiated well enough without ropes and a ladder.

  Sugiyama had the chills. He was unable to tell whether it came from fear or excitement, although the tingling sensation in his veins suggested more thrill than chill.

  ‘Well, are you game?’ Sakakibara whispered with a grin, as if he’d read Sugiyama’s mind.

  Looking back, Sugiyama once again confirmed their route as far as the shaft, and tried to persuade himself that this was definitely the last move. Once he had managed to reach the bottom of the shaft, he swore, there would be no stopping him making for home.

  Entering the ring of light from Sakakibara’s flashlight, Sugiyama pressed his back into the sloping surface and began his descent.

  ‘What’s it like down there?’ asked Sakakibara once Sugiyama was almost halfway down.

  Not responding to Sakakibara, Sugiyama had stopped and was straining his ears to listen. He could hear the faint sound of water dripping somewhere. He remembered hearing a similar sound at the mouth of the cave.

  ‘I can hear water!’

  No sooner had Sugiyama responded than Sakakibara thrust his hefty backside into the shaft.

  ‘I’m there!’

  Sakakibara started down after Sugiyama, and there was no stopping him.

  The shaft bottomed out in a gentle curve, which led to another level chamber of pretty much the same shape as the one before. It was a much smaller, bell-shaped cavern. A thin film of water covered the slippery surface of the cavern walls. So closely did the watery membrane adhere to the walls of the cave that you had to touch it to confirm that it was there at all. Percolating in through crevices in the ceiling, the water slid silently down the walls of the cavern to vanish through the floor of the cave without forming a single pool. The spectacle enthralled Sugiyama as he illuminated the area with his flashlight. He felt a surge of joy to think that he was the first person on the face of the earth to have witnessed this sight. It was the kind of moment savoured once in a lifetime, if at all. The power of the moment made Sugiyama forget the oath that he’d made to himself before entering the shaft. The fact that the descending water did not form pools but disappeared under the floor of the cavern suggested that there might be quite an extensive chamber below.

  Sugiyama and Sakakibara began searching for a route to that chamber. All feelings of self-restraint now thrown to the wind, Sugiyama was oblivious to anything else. The bait was too tempting, and he was being lured farther down into the bowels of the earth.

  In one spot, Sugiyama felt a slight draft of air. A subtle current of warm air came wafting up from some place.

  Sugiyama called Sakakibara over and sounded him out. Sakakibara knit his brows, deep in thought. There was no doubt about it; he too could feel air blowing up from somewhere. Yet there was no shaft visible nearby from which the air could be coming.

  Baffled as to where the source of the air could be, Sugiyama began moving slowly with the sensation of a faint draft on his skin. He then stood in a depression filled with piles of rubble. At his feet lay all kinds of rocks, both big and small. He used his light to survey the topography once again. The depression where he stood seemed to be shaped like a basin or circular crater. It occurred to Sugiyama that this may have been a sinkhole filled up by a cave-in. If so, all they had to do was remove the stones to uncover a shaft below.

  Both men began quickly shifting the stones, and eventually exposed quite a large boulder. They could feel a more substantial blast of air coming through gaps under this rock. Without a doubt, this was the boulder that was blocking the entrance to the shaft.

  Sugiyama and Sakakibara both tried to push the boulder to one side. It tilted to reveal part of a circular opening to the shaft underneath. Releasing their grip on the boulder would result in the boulder falling back to cover up the shaft. Thus, they redoubled their efforts with one more powerful push. With the base of the boulder now facing sideways, they wedged a stone in a niche to secure the boulder in place. Now the entrance to the shaft was completely exposed. Whenever either man moved, stones at their feet would roll down into the opening, bouncing off the stalactites to create a sound that reverberated like thunder. Both men waited until all stones likely to fall had fallen and the commotion had died down. After all, they did not want stones falling on their heads as they descended the shaft.

  Sugiyama made up his mind: there could be no turning back now that they had come this far. He resolved to see this through to the end.

  Tying a rope round a rock, Sugiyama released the other end, and it fell towards the bottom of the shaft. Although he felt capable of scaling the shaft without a rope, he wanted to take every precaution to ensure a safe return.

  ‘Wait here.’

  The tone of Sugiyama’s command was calm, yet clearly a command. Although the two men were the same age, Sakakibara was Sugiyama’s senior in terms of the number of years he had been a Pilot Caving Club member. It was thus with reluctance that Sakakibara nodded in compliance with what amounted to an order from a junior. Despite their relative positions at the club, Sugiyama far surpassed Sakakibara in terms of caving technique. Given the precariousness of the footing, one of them had to remain at the edge of the opening to make sure that the end of the rope remained in place, and Sakakibara was more suited to this task.

  As Sugiyama lowered himself inside the shaft, he felt apprehensive once again. He wondered why, but simply attributed it to Sakakibara’s annoying whistling. The man was looking down at him coolly now, all the while whistling some cracked tune. Sakakibara was all too relaxed, and this gave Sugiyama a nasty sense of foreboding.

  * * *

  Putting his foot on a small ledge, Sugiyama assumed a rest position. He began to contemplate the nasty premonition he had just had. This was supposed to be a virgin limestone grotto, one which no human had ever set foot in until now. Yet an uninvited flash of intuition suggested to him that sometime in the distant past, someone had tried to access this shaft just as he was attempting to now. It was an impression that must have formed unconsciously from having glimpsed some evidence of a prior presence.

  He brought his headlamp closer to a stalactite. The longer he inspected the wall, the more apparent became the bizarre pattern fashioned there. Daubed onto the contrasting ochre of the cave surface was dark-gray mud. He stretched out his hand to feel the surface. The pattern was clearly different from the cave surface. He wondered whether it was a motif that someone had intentionally fashioned there. No, he felt sure that wasn’t the case. He concluded that it was more likely to have been a muddy stain on the back of someone who had passed through the shaft just as he was doing now. As this person had been passing through, the mud on his back must have rubbed off onto the limestone wall.

  Sugiyama felt his energy rapidly ebbing away. The only reason he’d been tempted to this madcap adventure was the belief that no man had ever set foot in this gro
tto before. There was all the world of difference between being first and being second. Viewing this as a good a time as any, he called out to Sakakibara. As soon as he shouted, however, a hail of small stones struck him in the face. He immediately covered the top of his helmet with both hands for protection. Once the stones stopped falling, he looked up to see Sakakibara’s blue overall-clad form bumbling about, and then enter and block the shaft.

  ‘Say, Sakakibara!’ he shouted even louder.

  ‘Hang on! I’m coming down!’

  Unable to contain himself, Sakakibara appeared to be lowering himself down the shaft, feet first.

  ‘No, get out of there!’

  Their ensuing argument over who was going down or up lasted but a few seconds. A sudden shower of small stones was immediately followed by a loud boom, a brief scream, and the horrible sound of crushing bone. Then, as quickly, the shower of stones subsided. The lower half of Sakakibara’s body blocked the mouth of the shaft, preventing Sugiyama from appreciating the extent of the catastrophe that had just befallen him.

  ‘What’s happening up there?’

  He voice began to quiver, for he already instinctively knew that something was very wrong. Sakakibara failed to respond, but a short moan percolated through the gloom instead.

  Sugiyama made his way up until he could feel Sakakibara’s feet on his head. He flashed his light up through the gap between Sakakibara’s waist and the wall of the shaft. To his amazement, the space above the mouth of the shaft was no longer open; it was blocked by the boulder.

  He was stupefied. He felt the blood drain from his head. As he braved the dizziness, he regretted that they hadn’t properly secured the boulder. With every rock-slide, the boulder had tilted under its own weight to fall back to its original position, encountering and crushing Sakakibara’s head in the process. It was too cruel a punishment to be meted out to someone for simply having deserted his post. Yet Sugiyama could not suppress his desire to curse Sakakibara for his stupidity.
