When I read the Imperial command for the student mobilization, I received
the honor to go forth as a shield for the Emperor. This truly is the
long-cherished desire of a young Japanese man, and there is nothing that
surpasses this as an honor for the family.
Obtaining this joy today, still more I want to mention the gift of your
troubles for me. Now here I warmly thank you for your deep kindness for more
than 20 years.
Because I will go as an Imperial Japanese Navy man, from the beginning I
do not expect to return alive. I only will live for an eternal cause. I do
not have any words to state in a will, but I will record ideas and items.

— For a long time I was left the honor of a military family.
— The family's honor always is together with the country's prosperity.

I ask that you please handle the above items. As a Japanese person and as
the Koyama Family heir, I will carry out actions that will not be

"Like a shrine when the thick pillars are constructed with praise, now my
mother's image does not change." Until the last moment I will fight while
keeping your image deep inside.
I pray that you will have a long life of a hundred, a thousand years. My
spirit surely will return to your side.
Dear Older Sister,
I pray for Fujio's fortune in battle.
Please think well about the talk with Murata. He is a man who I as your
older brother want to recommend unconditionally.
I earnestly ask you to take care of things after I am gone. Death is easy,
but obtaining a place to die is difficult. A person's completion is
obtaining a place to die.
I go in high spirits. I am praying for the eternal existence of the
country of Japan and for prosperity of the Koyama Family.
