The sort of thing that people in their twenties enjoy
The Kanagawa Museum of Modern Literature have opened their
是ハtalentノ作品也 geniusノ作品ニアラズ。(アクヌケ)ノセヌ面白味ヲ有ス。二十代ノ人ノ喜ブモノナリ。英国流ノ趣味ナリ。"Undying Past"ノ方遥カニ優レリ
This is a work of talent, not a work of genius. It is interesting in an unsophisticated way. The sort of thing that people in their twenties enjoy. English in its taste. "Undying Past" was much better.
There's also letters, seal imprints, art, and even "relics": Sōseki's fountain pen! The fifth Sōseki 1000-yen note ever printed! The interface is a bit fiddly and I wouldn't want to do research through it, but as idle browsing material this site is pretty great.
Appreciative stranger:
This is amazing, and something I never would have found on my own. Thanks for pointing it out!
