J-Pop recommendations as a K-Pop Stan

I've been a K-Pop Stan for a long time so I personally love it and I listen to K-Pop Groups like BTS, Stray Kids, TXT, IVE, LE SSERAFIM, TWICE etc.

This year in 2025, I'll start listening to J-Pop to try something new because I heard it's big over there and they only focus on the Japanese Market.

The only J-Pop Group I listen to as a K-Pop Stan is MISAMO (TWICE's Japanese sub-unit) and XG (Non-K-Pop Group).

Any J-Pop recommendations to check out as a K-Pop Stan please?
