Japanese Literature discussion

I am looking to read a book of a Japanese author about World War 1 (or written/indluenced by that era). Can anyone advise me on some titles or suggest something?

Thank you in advance.

Nice question. The Japanese First World War was very different to Europe's and, I guess, of less importance than the Russo-Japanese War and then everything kicking off in China in the 20s.

Some Japanese writers and what they were up to: Natsume Soseki wrote Kokoro just before the war started and then he died in 1916, Mori Ogai was in his historical fiction phase, Nagai Kafu was back from the States and doing his "stories about what I get up to in Tokyo" thing, Arishima Takeo's amazing "A Certain Woman" was published in 1916, Uno Koji was writing fictional accounts of what he was getting up to in his daily life, Akutagawa Ryunosuke wrote many of his stories whilst the war was raging in Europe (Hell Screen was published in 1918)...
