Kwaidan (1964)
If you like Kuroneko, please watch it.
It is an anthology of four folklore tales, including Yuki Onna, the most famous and popular of japanese folklore.
The film is gorgeous and it looks like a play.

Possession (1981)
This film is pure crazyness.
It is about to born a more toxic and self-destructive couple.
It is peak psychological horror start to finish.
I recommend it for newly-weds.
Also, it is confirmed that a remake is being made.

The VVitch (2015)
One of the best witchcraft horror films of the last years.
I really love it back then and still love it today.

The Night House (2021)
A very underrated gem, in my opinion.
It is very psychological and makes the viewer thinks if iwhat it is happening with the protagonist is really supernatural or just psychological.

The Dark and The Wicked (2020)
Another underappreciated title.
When Evil Lurks reminded me a lot of this film, both have a similar premisse of an evil lurking and affecting the place and the characters.

I Saw the Devil is a total banger! And thanks for the list, there’s 3 or 4 here I need to check out

I won't argue with that – it's my third favorite of the 2010s behind Wailing and I Saw the Devil
Here's my full list

It’s way up there but my vote has to go to The Handmaiden
