"Sakura" is the Japanese word for cherry blossom. If you are asking about a school or campus with cherry blossom trees, you can say "sakura campus" or "cherry blossom campus." For example, you might say "I love going to school in the spring because our campus is covered in cherry blossom trees" or "The sakura campus is my favorite place to be during cherry blossom season." You can also describe the campus as having a "sakura theme" or being "decorated with cherry blossom trees."
