At 1130 on April 14, 1945, Lieutenant Junior Grade Takahiro Kumakura took off from Kanoya Air Base
as pilot in a Zero fighter carrying a 250-kg bomb and died in a special
(suicide) attack east of Tokunoshima at the age of 22. He was a member of the
Kamikaze Special Attack Corps 2nd Tsukuba Squadron. After his death in a special
attack, he received a promotion to Lieutenant Commander. He was from Tochigi
Prefecture, attended Senshū University in Tōkyō, and was a member of the 13th Class of the Navy's Flight Reserve
Students (Hikō Yobi Gakusei).
0630, line-up, finally it is the sortie.
Waiting for the weather report to come, we are standing by at the
airfield. Everyone took photos. With the Tsukuba Unit, this is our farewell
to this world.
I must participate in tomorrow's general attack. At 0940, we took off
with everyone seeing us off. The 21 planes that took off circled for a while
in the skies above, passed through the skies above Tōkyō, and headed
straight toward Kanoya Air Base. Along the way, the weather did not become good.
When we got to Kyūshū, we flew straddling the east coast. I saw Tomitaka
Airfield, and in a while we were above Kasanohara and then reached the
skies over Kanoya. We flew around once and landed on the runway. The dust
clouds were tremendous. All planes landed safely, and we gathered together.
Sunset was at 6:30. In the darkness we departed for classrooms here at an
elementary school. The aircraft maintenance workers are doing maintenance through the
night. They are preparing for tomorrow's sortie. We slept with the clothes
that we had on. All of our heads lined up, dreaming of tomorrow's sortie and
an instant sinking. When I went out to wash up before sleeping, I met
Lieutenant Hayashi. In this strange place for the first time in a while I
told tales of long ago. It brought back memories. Narita also was there.
I slept well. I washed up in the current of a creek. After finishing
breakfast, from 0800 Commander Nakajima talked to the Special Attack Corps
members. From 0900, with the communications officer we made arrangements
regarding radio telegraph codes and contact steps.
10:00, with a short time I am writing hastily a final letter. I enclosed
two or three double cherry blossoms and put in place my bags. I now have no
regrets. After a few hours I will go and make a splendid taiatari
(body-crashing) attack. There is no formal last letter, but I feel calm with
only writing a while.
11:00, lunch, immediately gathered at airfield command post. They
designated groups of kutai (typically four aircraft) with various
colored mufflers such as white, red, yellow, purple, and blue, and the young
warriors gathered together. They wore hachimaki (headbands) with a
red circle over their flight caps, and the hachimaki trailed down
their backs. I feel we are like the Byakko (White Tiger) Unit 
from long ago. 12:00, 10th Air Fleet Commander held naming ceremony. As early as
1:00, 1st Kutai headed toward Okinawa with a 250-kg bomb hanging from wing.
They raised a dust storm when they started. They made a sortie that will
lead to a watery grave at the bottom of the sea for all of the thousand and
several hundred ships including transports, cruisers, battleships, and
My own kutai number also finally came. The departing aircraft were
sent off by the commanding officer, Commander Nakajima. They pulled the
aircraft out from the bunkers, and he commanded all of them to line up on
the runway. In the instant when I was trying to take off, a bomb somehow
dropped from where it was held. Unfortunately, they pulled the aircraft off
the runway and tried to again hang a bomb, but they were not able to do so
as the hanging mechanism was completely damaged. Regrettably when they looked back, it was
discovered that the fourth plane also had dropped its bomb and was stopped.
Evening was approaching, and I had a feeling the attack would be in the
evening. When the second and third aircraft were about ready to take off,
they came running to the takeoff point, and the second and third aircraft
seemed to see their concerned faces. They signaled them with flags to go.
The pilots acknowledged the instruction and took off. When they returned to
the aircraft and looked at the bomb, the maintenance workers worked hard to
fix it, but in the end they had to replace the mechanism that held the bomb.
Ah, I wonder what it could have been. I have fallen behind!
I felt bitter and resisted weeping. I reported to the commanding officer.
He indicated that if the repairs could be completed in 30 minutes then we
could depart, but if the departures were stopped then we would be moved to
the next date. When I looked to see whether I was alone, Ensign Ichinoseki
on the fourth aircraft also was crying on the grass. The majority of the
aircraft had their bombs dropped, quickly did the repairs in time, and took off .
Although I tried to not cry, I could not control the dropping tears, what a
disappointment! Three of us cried before the buntai commander. We
truly had a failure!
Since the sun set and it became dark, we returned again to the elementary
school, but I did not want to mix with others. I was dizzy inside my head.
But two subordinates were before me, and I could not be discouraged.
Regrettably I showed a distressed face, and I said that certainly I would
participate in the next attack. I vowed that my battle results would be more
than twice as much.
I was not able to sleep. I did not need a meal either. I am full of
bitterness. I did not listen at all to the words of the head officer. The
words of the buntai commander also were no good. I do not understand
this feeling. Ah, why do I have bad luck?
About this time everyone has turned the surface of the Okinawa Sea to
crimson red, and what was floating has been sunk and what was flying has
been knocked down. As they are laughing they are waiting in the other world
for me to go. Looking at my watch, I think that it is about the time that
the last planes have attacked. About now the skies around Okinawa must have
changed to deep red and the seas must be afire.
The cold has come again.
A strong wind struck, and a Suisei dive bomber had to drop its
extra fuel tank to gain control. The plane had made a sortie in the early
morning and was searching for the enemy. The skies to the east are clear.
The southwest has low dark clouds hanging down, but the skies above are
They said that we would make a sortie today, and since early morning we have
been standing by. There is no longer free time to write this diary. Now I
will stop writing. I wonder by whose hands it will be delivered, but I want
to request that my warmest regards be given to my Father and Mother. During
today's sortie, I certainly believe that I will get a souvenir. I'll enjoy
in the other world the souvenir of a large aircraft carrier. Seeing my
extremely rough writing is surprising to me. A search plane has taken off
again overhead. Our sortie probably will be soon.
Underneath my flight cap I am wearing a tightly-wrapped hachimaki
(headband) with a red circle. I certainly will accomplish an instant
sinking. Basking in the morning sun, my plane is on standby. When the order
comes down, our fighters will take off and fight in a few seconds. Look,
Japan's morning breaks! With an extraordinary feat I truly will make a hit.
Go, young eagles! Burn with the spirit of hissatsu hitchū
April 12, 10 a.m. Farewell.
I pray for everyone's happiness.
