Pardon me, these are probably normie, Im new to Japanese music and trying to discover more.

Not sure if Noa counts, but it fits the sound, just discovered this and really love this song.

Particularly as someone who wishes I could have that Japanese school experience, but cant obviously. It was just really sweet to see the pictures and clips. Almost like I could imagine what it was like to have nostalgia for this. It was nice.

Could totally be an anime opening. Really need more music like these.
