If you liked Byousoku 5 Centimeter, then you might also enjoy reading Kotonoha no Niwa, since both stories come from the desk of Shinkai Makoto, so the way of narration & overall atmosphere are similar. They touch such themes like one's isolation & relationships between the others, as well as they talk about love interest, & desire to keep the other person close. Both of them are also thought-provoking & nostalgic.
Both are short bittersweet romance tales from director/author Makoto Shinkai with themes of separation and heartbreak. Kimi no Na wa differs with supernatural elements while Byousoku 5 Centimeter focuses more on the relationships between characters. If your a fan of Makoto Shinkai or short romance tales you'll be sure to like these works.
Sad drama stories about distance between people and also distance in love. In both characters try to reach themselves, but in another way. Both have the same, melancholic feeling, though Kimi ni Shika Kikoenai is more dramatic.
