First thing that comes to mind is this Japanese artist called Tnaka that I algorithmically got the lucky draw in coming across her on Twitter. Genre wise, I dunno how exactly I would categories her but her words are "nostalgic and full of pop vibes!" so we'll go with that. She's got a fun fashion sense by the way, just wanted to add that
All her music so far can be found in her album that was released in 21st of August 2024 called "Tnaka IN THE HOUSE" and my personal favourites in this album are: Who's that?! & Happy Unbirthday
Likes she's obviously not an amazing singer but her vocals are pretty charming to me regardless
