Last Letter of Ensign Kōzō Koizumi to His Parents

At 1423 on April 29, 1945, Ensign Kōzō Koizumi took off from Kanoya Air Base as pilot in a Zero Fighter Trainer carrying a 250-kg bomb and died in a special (suicide) attack off Okinawa at the age of 21. He was a member of the Kamikaze Special Attack Corps 5th Shōwa Squadron from Yatabe Naval Air Group in Ibaraki Prefecture. He was from Kanagawa Prefecture, attended Yokohama College of Commerce, and was a member of the 14th Class of the Navy's Flight Reserve Students (Hikō Yobi Gakusei).

He wrote the following final letter:

Dear Father and Mother,

I think that tomorrow we in the Shōwa Unit also finally will receive an order in the OO [1] No. OO Operation.

As long as the enemy task force does not appear again, we will make sure-hit taiatari (body-crashing) attacks on enemy ships where they are at in the anchorage at Nakagusuku Bay or Kadena Bay at the main island of Okinawa, and we will destroy them completely.

Under a dim oil lamp with all of my preparations completely finished, I am writing my final letter with a peaceful feeling.

Please imagine me as Father's son standing calmly and full of self-confidence. It is best that you have no worries at all concerning me and that you be at ease.

Finally, I deeply thank you for your kindness to me. I pray for your health and for great joy for the Koizumi Family.

April 27, 10 p.m.
