if you look for something very traditional to do you need to visit a hot spring. its perfect to arrive in the afternoon spend a night and leave next morning. you go back to busy tokyo as a new person. place we went was called tsubaki and was by the sea one and half hour drive from tokyo by car. there’s also bullet train option. food there was nothing for “western sushi” lovers. this is a proper japanese stuff where you have no clue what you eating because the lady serving your food speaks english with the strongest japanese accent so her explanation leaves a lot of room for your imagination.
