I LOVE JUNJI ITO
Seriously he’s one of my favorite people in the world, ever. I strongly recommend every single one of the stories @GDBringer linked above. I also recommend the Tomie series and Uzumaki, some of his most famous stories.
Also yes, he’s very very famous and widely regarded as one of the most iconic mangakas to have ever lived. Here’s The Guardian talking about him. He’s widely appreciated in both Japan and worldwide and several movies have been made based off of his mangas, and many other movies, books and visual artists took inspiration from him.
Some Japanese movies that try to capture his stories in film are Spiral (2000) and Gyo: Tokyo Fish Attack (2012).
An American movies I’m sure was inspired by him (and many other things) is Annihilation, available on Netflix.
There has also been a recent anime anthology series by Shinobu Tagashira. It has Long Dream in it, one of my personal favorites from Ito. Maybe @Truly would be interested in it?
EDIT: these are all very different kinds of horror, written at completely different points in time.
Omelas is absolutely haunting for how real it is; it’s not what you expect at all, and it’s not afraid of holding back on delivering its horror until the very end.
Sankings is science fiction, and it’s frightening at that. There’s a sense of dread that permeates every page, and the ending will never, ever, leave you – my dad has been trying for some 30 years to no avail.
The Nameless City is Lovecraftian to the bone, and its surreal and bizarre elements are what make it scary and ominous.
The Masque of the Red Death feels very Victorian and visually stunning to me; Poe knows how to make his words feel vivid, and balances well reality with fiction.
It’s the future, and a family buys a new home. It does everything for them, especially the nursery, which, through the children’s imagination, can take them anywhere in the world…
