Like a white cascade, the squall swept over the Wakashio VII, a deep-sea fishing boat with a hold full of tuna. Once having passed, the squall swept over the sea in a southerly direction. The rainbow that formed in its wake appeared to be a triumphal arch welcoming the boat back to its home port. A few hours earlier, they had passed through the sea off the Ogasawara Islands, and a short journey further north would bring into sight the profile of Torishima Island. Heading further north, they would reach the island of Hachiojima. Kazuo Shiraishi had a growing sense of relief, as if they were already back in Japan.
As Kazuo stood on bridge watch, it gradually sank into him that the yearlong voyage was finally drawing to a close. This was his third such voyage. Yet his heart felt fuller than it had upon returning from his first. This was no doubt due to the period of extended idleness that awaited him before the next voyage.
Upon returning from his second voyage seven years ago, Kazuo took up work in a fisheries warehouse as a cargo superintendent in charge of grading tuna fish. His memories of that second voyage were not pleasant; he had become particularly annoyed by the ugly mood that prevailed among the crew. He consequently applied, though not in so many words, for a job on land.
Despite being qualified as an engineer, he continued to cling to his land-based job at Wakashio Fisheries for the next five years, persistently rejecting any possibility of returning to sea.
Then two years ago, while driving the firm's van to Tokyo, he became stuck in heavy traffic. He was overcome by the claustrophobia of being surrounded on all sides by trucks. In that instant he realized that he really didn't belong on land after all. He belonged at sea with its unimpeded vistas. To describe how the sun set at sea, Kazuo would often form a circle with his arms, although such a gesture could never truly capture the actual grandeur of a sunset at sea. Whenever, stuck in congested traffic, he happened to recall a seascape, the beauty of the scene felt all the more poignant. How deep was the calm silence at sea compared to the deafening din of traffic! Thus awakened to the lure of the sea as if for the first time, Kazuo resolved that it was time to set out on a third voyage, and promptly contacted the company to this end.
As the ship's assistant engineer, Kazuo had been satisfied with this voyage. With a respectable career under his belt, he was regarded by everyone aboard as a full-fledged seaman. No one treated him like some green cabin boy as they had on his last trip, and there had been no feuding factions aboard the boat this time. Having successfully completed its mission in the South Pacific, the Wakashio VII now had its refrigerated hold full to the brim with large southern blue fin tuna. Moreover, they'd encountered no conditions during the voyage severe enough to be considered life threatening. All in all, the voyage had gone off as planned. The entire mission would have been perfect had it not been for an incident in which two crewmembers were swept overboard off the coast of New Zealand. Miraculously, one of these men was rescued, a feat that caught the attention of the newspapers. Sadly, the reporters focused exclusively on the dramatic sea rescue, totally ignoring the fact that another man had lost his life in the incident. While saddened by the death of a crewmate, the ship hands were also overjoyed that another, earlier given up for dead, had been returned to them. What should have been seen as a tragic event strangely gave rise to the jolly mood of a carnival. Perhaps this was because the lost crewmember hadn't been very popular.
The triumphal arc of the rainbow appeared just two or three days before they were to reach the Japanese mainland. As Kazuo stood at watch on the bridge, a smile came unnoticed to his face. The voyage had garnered a huge catch. He stood to make a pretty penny. Thinking how he'd spend this money, he couldn't help but grin.
Just one of the ways he could spend the money was to cover the costs of his wedding. Kazuo had turned twenty-seven during the voyage and was seriously considering marrying a girl back home. During the voyage he had finally decided to formally propose to this girl upon his return. As for any future deep-sea fishing voyages, the two of them would have to discuss it first and decide if that was what they both wanted. If she opposed any future trips, he'd listen. As Kazuo thought things through, he realized that this could be his last voyage. That this might be his last homecoming made the moment on the bridge all the more emotional for him.
As the clouds that fuelled a squall fell behind in the distance, shafts of summer sunlight began streaming down through the clouds ahead, forming patches of light and dark on the face of the sea like so many spotlights. It was three in the afternoon. Ahead to port could be seen the profile of a boat that resembled a yacht as it slid from a dark area into a patch of light. After straining his eyes in that direction, Kazuo used his pair of binoculars to make sure. It was in fact a small oceangoing cruiser. Although the vessel seemed to have emerged from a gap in the clouds themselves, it was heading directly toward them on the portside as though to cross paths with the Wakashio VII, which was running on autopilot. Kazuo gave five consecutive blasts of the steam whistle. In addition to indicating alarm about the cruiser's direction, they were meant as a warning. After sounding the whistle, Kazuo peered through the binoculars again. The cruiser was travelling with its sails down. There was no sign of anyone onboard. There should have been someone standing watch on a boat of that kind, no matter what the circumstances. Without someone to keep watch, there was always the risk of a collision.
Kazuo sounded the whistle again, while observing the cruiser through his binoculars. Nobody appeared on deck.
He wondered if their whole crew was fast asleep in the cabin. He certainly couldn't think of any other way to explain the total absence of anyone on deck. Looking suspiciously like a phantom ship, the cruiser bore down on a collision course with the Wakashio VII.
Kazuo lost no time in calling Captain Takagi and informing him of the situation. The captain silently scrutinized the cruiser with unaided eyes as Kazuo waited.
'Odd, very odd,' muttered Captain Takagi at last before putting the ship's engine in neutral. With the engine idling, the boat continued to drift forward for a while under its own momentum, before it finally came to rest. The hull of the cruiser was by now right below the deck of Wakashio VII. Closer inspection revealed that what they had taken for a small cruiser was actually a luxury yacht about forty feet in length. Its deck was white and the rest of the hull a regal maroon, with double lines running along the side. They could see a diving platform mounted on the beautifully curved stern. It was obvious at a glance that the yacht's owner was extremely wealthy.
Seamen assembled on deck in twos and threes along the portside. From there they called down to the yacht.
'Anyone down there?'
The repeated shouts of the men brought no response from the yacht. Not a single face emerged from the cabin below. A forty footer of this type would normally be manned by four or five crewmembers at the very least.
'What should we do?'
Boatswain Shibasaki turned to the captain for instructions, a scowl on his face. It was clear he just wanted to forget this matter and head on full-speed ahead toward their home port of Misaki.
'Well, we can't pretend we haven't seen it.'
Captain Takagi then unfolded his arms and ordered the junior seamen to lower a boat. The yacht could have been in an accident, and he couldn't just ignore her and forge ahead. It was the duty of all seamen worthy of the name to come to the aid of ships in distress.
A rope from the Wakashio VII was tied firmly to the bow cleat of the yacht. Once they'd prevented the vessel from drifting away, a seaman boarded the yacht. He quickly surveyed the cabin quarters before shouting back.
