『太陽と鉄』は、
三島由紀夫の自伝的随筆・評論。

三島自身は「告白と批評との中間形態」としている。

主に自らの肉体と精神、生と死、
文と武を主題に書かれたもので、
三島の文学、思想、その死を論じるにあたり、
重要な作品である。

最後まで冷徹な自己分析、自己認識の中で、限りなく客観的、論理的世界へ飛翔して、自らの死と対決する三島ミスチシズムの精髄を明かす「太陽と鉄」

"Sun and Steel" is an autobiographical essay and critique by Yukio Mishima.

Mishima himself described it as "an intermediate form between confession and criticism."

It is written mainly on the themes of his own body and mind, life and death, and literature and martial arts, making it an important work when discussing Mishima's literature, thought, and death.

"Sun and Steel" reveals the essence of Mishima's mysticism, in which he soars into an infinitely objective and logical world, confronting his own death, in a cold-hearted self-analysis and self-awareness to the very end.
