 Tokkō no shima 5 (The Isle of Tokkou 5) continues with the story of 
Flight Petty Officer 2nd Class Yūzō Watanabe, kaiten human torpedo pilot. 
Volume 4 ended with him passed out in his kaiten due to toxic fumes from water 
that had leaked into the kaiten. On January 15, 1945, the I-53 submarine, which 
had carried three kaiten to Kossol Passage in the Palau Islands, successfully launched two 
kaiten weapons at Allied ships in the anchorage, but 
these two did not reach any target before exploding. Watanabe's kaiten failed to 
launch from the I-53 submarine, so the captain ordered his submarine to surface 
so a rescue attempt could be made, since there is no passage from the submarine to 
Watanabe's kaiten. Volume 5 begins at the point when the I-53 submarine has 
finished surfacing despite enemy ships within firing range. Several crewmen exit the submarine hatch and hurry to Watanabe's kaiten while 
enemy ships fire at the submarine. They carry the unconscious Watanabe from the 
kaiten back to the submarine entrance. As the hatch is closed, a torpedo launched from 
one of the enemy ships hits the submarine but appears to cause only minor 
damage. Four enemy ships soon start to drop depth charges on the submarine that 
has dived as deep as possible. One wounded crewman, who thinks everyone will 
die, can hold back no more and blames the submarine's precarious situation on 
the captain's decision to surface and rescue Watanabe from the kaiten. The 
captain tells the crewman to calm down and says they can escape as before 
when depth charges were being dropped on them. The manga comic effectively depicts the apprehension and terror of the 
submarine crew who are hearing and feeling depth charges explode around them. As the 
I-53 submarine remains deeply submerged for several hours, the oxygen level and 
batteries become low, and the inside temperature heats up to nearly unbearable 
levels. The crewmen beg the captain to have the submarine surface so that they 
can die fighting rather than in vain deep in the sea. The captain finally orders 
the I-53 to surface, and the crewmen are overjoyed to find high waves, a hard 
rain, and nearly zero visibility. One crewman shouts that this miracle came 
about due to a kamikaze (divine wind) that blew. The submarine gets through the 
enemy ships and returns to the kaiten base at Ōtsushima in two weeks. When Yūzō Watanabe was recovered from his kaiten and carried inside the 
submarine, he was given oxygen. However, he remained unconscious for several 
hours, and he did not regain consciousness until the submarine surfaced during 
the driving rain. During his unconsciousness, he dreamed that he was in a small 
boat heading toward the torii gate at Kudan, which is the hill in Tokyo where Yasukuni Shrine 
is located. Yasukuni is the place where the spirits of dead soldiers were said to go. Around him in other small 
boats were kaiten pilots who had died already such as Masao Sekiguchi, 
Watanabe's close friend whose kaiten saved the I-53 submarine when it drew away 
three enemy destroyers to allow the I-53 to escape, and Lieutenant Junior Grade Sekio 
Nishina, one of the co-creators of the kaiten weapon who died when his kaiten 
successfully crashed into and sank a large oil tanker at the Ulithi anchorage on 
November 20, 1944. In Watanabe's dream, the others reach a large ship and climb 
up rope ladders to the deck. The dream ends as the voice of an unseen person 
from the ship tells Watanabe to live. Watanabe returns extremely depressed to the kaiten base at Ōtsushima, since 
he did not carry out his mission of crashing his kaiten into an enemy ship. On 
February 11, 1945, officers meet at naval headquarters in Kure to discuss the 
results of the Kongō Unit, which included six I-class submarines that each 
carried four kaiten weapons. They conclude that 18 enemy ships in total have 
been hit and sunk by kaiten launched from Kongō Unit submarines, even though 
after the war American records showed that no ships had been sunk. Watanabe begs 
the kaiten base commander at Ōtsushima to be assigned to the next kaiten 
mission, which is the Chihaya Unit scheduled to sortie on February 20 with 14 
kaiten on three I-class submarines. The commander refuses his request, since he 
strongly believes that a kaiten pilot should not be sent again on a mission if 
he failed in the initial one. Watanabe is assigned as an instructor and 
accompanies a trainee inside a kaiten when there is a training run. Volume 5 
ends with one of the top officers lecturing 
kaiten pilots, including the Chihaya Unit pilots and Watanabe. He exhorts 
them to achieve battle results and apparently refers to those who do not as 
cowards. He says, "If the [kaiten's] screw does not turn, try to turn it 
even by 
your hands and plunge into a ship." The manga story's last frame of Volume 
5 shows 
Watanabe in anguish as he hears the commander's words. Volume 5, like previous volumes, has sparse dialog with an emphasis on drawings 
that illustrate the emotions and actions of the characters. The manga series is 
based on historical facts with a few minor changes. In real history, the I-53 submarine 
actually carried four kaiten manned torpedoes 
to Kossol Passage in the Palau Islands (Konada 2006, 116-25; Mediasion 2006, 47, 
80). Three kaiten weapons were launched in the darkness of the early morning of 
January 12, 1945. The final kaiten 
piloted by Ensign Minoru Kuge filled with gas prior to his launch, and he passed 
out before the order for launch. The submarine surfaced in the darkness and 
recovered him. Kuge's experience has similarities to the fictional account of 
Yūzō Watanabe. Sources Cited
