J.League 2024 and beyond

A little off topic - any recommendations for spots to visit in Japan that are a little slower/quieter? Taking my mum over next year and wouldn’t mind some quieter areas to consider. Mostly thinking Honshu with possibly a run to Sapporo. Current thoughts were Kanazawa as an alternative to Kyoto. Izu peninsula for some nature walks. Maybe Nagano for a snowy spring experience ratehr than Sapporo (time constraints).
