What good Japanese love movies are there?

These are some Japanese love movies that I think are very beautiful:

1、

Love letter)-A woman wrote a love letter after her ex-boyfriend died, but she got a reply. She began to pursue this mysterious identity.

2. The sky of love)-Two young people met in high school, and their love relationship was tested, thus deducing a touching story.

3. "5 cm per second"-This film tells the love story of two young people from elementary school to high school, and discusses the complexity of long-distance love.

4. Our little sister)-Four sisters met their half-sister after their grandmother died, and their fetters and love life began a new chapter.

5. The Image of the Fire Woman-A female painter took a fancy to a male model, and her life and creation began to change.

These films have unique artistic beauty and profound feelings. I hope you like them!
