 If you liked Sen to Chihiro no Kamikakushi |  ...then you might like Hotarubi no Mori e |
Both are movies talking about a human that encounters a resident of spirits, in Spirited away it's a town and in Hotarubi no Mori e it's a forest. In both a human girl becomes a friend with one of the spirits and later falls in love with it. Both are lovely supernatural stories.

Everyone already spotted the similarities. Both movies have spirits, girl and boy protagonists, but it's shorter and sadder.
Both have supernatural elements and are about when a human interacts with spirits. They also have slightly similar themes of romance.

Both stories revolve around a helpless, innocent little girl as a protagonist, who then is aided through the challenges she faces by a mysterious boy. As you watch through the film, you will see the relationship develop slowly between the two characters. As said in the previous posts, yes they also have that same supernatural related genre, and they both will also have that bittersweet ending as well.

Very warm and sweet. A young girl is involved in a "true love" relationship with a non-human which ends somewhat prematurely and moves on in life. The portrayal of love is meant for a younger audience. There is somewhat a bittersweet feeling at the end, but with the emotional development of the main character, you cannot help but to feel happy for them.

A girl encounters spirits, which then revolves into a story about the spirits and the girl either growing up or realizing things about herself. Both movies also include a huge amount of japanese mythology.

There are spirits. The girl wanders around the place and suddenly stumbles to the land of spirits and ghosts. Great storyline. A must see anime movie.
