Recomandations for a getaway alone or two females!

Hey everyone,
I’m based in Ōta-ku, near Tokyo, and I’m itching to get out of the city for a bit. I’d love to explore:
-Countryside spots with beautiful scenery
-Cool and unique shrines
-Multi-day trips with fun activities
-Hidden gems that aren’t completely packed with tourists
I’m fine with hopping on a train or bus for a few hours — I just want to experience a slower, more traditional side of Japan.

If you’ve got any favorite places or personal tips, I’d really appreciate it!

Thanks a ton 🙏
