Private Akiyoshi Hisaeda, from the Ehime Prefecture of Shikoku, kept a diary as he sailed to Rabaul aboard the transport Venice Maru. He described the conditions as “very cramped and uncomfortable,” and noted that the temperature inside the ship reached 43 degrees Celsius (110 Fahrenheit). Life inside the other transports was equally awful. There was little fresh water, and the crude wooden benjos (latrines) were up on the main deck, which also happened to be where the meals were cooked. Down below, everyone was tormented by hordes of flies.The South Seas Detachment [南海支隊 Nankai Shitai], under Imperial Japanese Navy command, was mostly drawn from Japan's 55th Division, which was recruited primarily from Shikoku and played a key role in the Burma Campaign. The 55th Division's home base and elite POW camp was Zentsūji. The POWs included about 200 Americans captured by the South Seas Detachment on Guam and Wake Island, a few dozen mostly British prisoners from Singapore, and 60 Australian officers from Rabaul. The Zentsūji POW camp was a Potemkin village to impress International Red Cross representatives with Japan's humane treatment of its captives. Most of the rest of the men captured in the Rabaul Campaign died aboard the hell ship Montevideo Maru en route to Hainan Island, when it was torpedoed by an American submarine, the USS Sturgeon, on 1 July 1942. The loss of those 1050+ men was Australia's single worst military disaster of World War II.
The Japanese soldiers were no strangers to terrible conditions or harsh environments. Their rigorous training system, based on the principle of instant obedience achieved through strict discipline, had prepared them well. From the moment they began training as recruits, they were immersed in a culture of degradation and abuse, a rude awakening for people who had spent their entire lives learning group harmony. Not only were recruits cursed and shamed in front of their peers, they were also beaten regularly. Sometimes they were hit on the buttocks with wooden sticks, other times they were slapped, usually with an open hand but occasionally with the sole from a hobnailed shoe. Many instructors were sadistic, barely more than thugs, and they had tremendous latitude to punish recruits with methods calculated to break down every vestige of individuality. Frequently the entire class or platoon received the same punishment: If one suffered, all suffered.
One of the cruelest penalties was meted out during evening meals. Picked at random, recruits were ordered to recite by memory from the Gunjin Chokuyu [軍人勅諭 aka 'Imperial Rescript to Soldiers and Sailors'], “Emperor Meiji’s Instructions to the Men of the Fighting Services.” First issued in 1883, it exhorted warriors to carry out their duties with loyalty, propriety, valor, faithfulness, and simplicity. The wording was archaic, difficult to memorize, and if anyone made a mistake or forgot a passage, he was forbidden to eat. For recruits already bruised, exhausted, and ravenous from the day’s training, the denial of food was excruciating. After six months or more of such extreme conditioning, the recruits emerged as well-disciplined soldiers, their “bodies and minds tempered hard as steel.” The men of the South Seas Detachment were no different, and could tolerate anything that nature or the Imperial Army could throw at them.
WHEN THE INVASION FORCE REACHED THE EQUATOR AT 0500 ON JANUARY 20, the South Seas Detachment paused to commemorate a special event. In all of Japan’s 2,600-year history, they were the first army force to cross the line. Miyake later described the scene aboard his vessel: “On the day we crossed the equator, all the men, fully armed and equipped, assembled on deck. ‘At this time, when we are about to … advance into the southern hemisphere, we shall pay our respect toward the Imperial Palace,’ said the commander toward his assembled subordinates. Solemnly, and with overflowing emotions, the men presented arms toward the north.”
