This song is "Haru wo Tsugeru" (Announcing Spring) by yama.
The original key is D#m (6 sharps), so I've raised it a semitone to Em.
This sheet music is for beginner piano solo.
I've tried to make it easy to play.
Finger numbers are included, so please use them as a reference when playing.
The 16th note swing is quite challenging on acoustic instruments, so I think playing it at around 110 quarter notes (the original tempo is 120 quarter notes) would be just right.
(The reference video is also at 110 quarter notes.)
