In case you are not from Japan (which your name would suggest
)you should for sure try
Akinari Ueda's
Ugetsu Monogatari (Tales of Moonlight and Rain)
Also Akutagawa Ryunosuke's
Kappa and his other short stories
You might also be interested in Lafcadio Hearn's
Kwaidan: Stories and Studies of Strange Things
I also like Miyazawa Kenji's
Ginga Tetsudo no Yoru (named in English as Milky Way Railroad/Night Train to the Stars/Fantasy Railroad In The Stars) though many think it's for children...
