I'm obsessed with every single thing I read from Junji ito. I'm usually not very into horror, I dislike reading/watching most of the horror stories that includes paranormal events, spirits, scarejumps, ghosts, gore, etc.

I believe I've read most of his comics, but (you need an account to see links) is still my favorite story.
If someone wants to start reading something from him, I'd suggest starting with Uzumaki, that is his most popular story:
