Rambalac is so nice - I have been watching his videos for many years & even retraced his steps a couple times during actual trips tp Japan.
One interesting channel I started watching recently is called Watatabi: https://m.youtube.com/@watatabi
Its quite different from Rambalac - called Watatabi: https://m.youtube.com/@watatabi
Its a channel about exploring more remote places, like ancient onsen ryokans, scenic places & natural landmarks. Unlike Rambalac there is editing and naration but in this case it kinda fits the different scope & the places visited are super interesting. :)
