三島由紀夫、本名平岡公威（みきたけ）がいつペンネームを使いだしたのか、長年の謎が明かになりました。
Discovery shows how Mishima adopted pen name at just 16
A literary sleuth has finally solved the mystery of how Yukio Mishima adopted his pen name.
The discovery was made in a handwritten version of what appears to be an original draft of Mishima's first literary work when he was just 16.
The cover has two lines drawn through Kimitake Hiraoka, the name Mishima was born with, and "Yukio Mishima" written alongside.
Hideaki Sato, a professor of Japanese literature at Kindai University who has devoted his career to studying Mishima's works, called the discovery "a valuable draft that can be considered the birth of 'Yukio Mishima' as a writer."
The draft was found in Kumamoto and is for a 56-page work titled "Hana Zakari no Mori" (The forest in full bloom).
It had been in the possession of Shoichi Hasuda, the eldest son of Zenmei Hasuda (1904-1945), a scholar of Japanese literature who was born in Kumamoto city.
"Hana Zakari no Mori" was published in 1941 in the literary journal Bungei Bunka that was edited by Hasuda and Fumio Shimizu, who was also from Kumamoto Prefecture and then a teacher at the Gakushuin Junior High School where Mishima was a student when he wrote the work.
Even though Mishima was only 16 at the time, the lyrical piece about the protagonist's feelings toward his ancestors already showed signs of the literary giant that Mishima would become

今回取り上げるのはadoptです。
この文脈に合う語義を『ジーニアス英和辞典』（第五版、大修館書店）で調べると「（新しい名前・肩書などを名乗る：（国）を選ぶ：（言語）を借用する）とありました。
LDOCEでは“to choose a new name, country, custom etc, especially to replace a previous one”と定義されています。
adoptといえば「養子にする」が思い浮かびがちですが、ラテン語で“to”を表す“ad-“と“choose”を表す“optare”から派生したようです。(flyingbird)
