Will it be troublesome to travel to Japan without joining a group?

Go to Japan alone in summer 15 days. Similar to your idea, I don't want to step on the scene with the group, so I choose to travel freely. But you still know Japanese, and I don't know Japanese. I am very happy about this situation, so please set out boldly and share some points: 1. Do your homework before you leave. I bought two books, started a self-help tour in Japan and went to Tokyo by subway. The first one is to give you a general idea of the whole trip, and the second one is a more detailed road map, which you can choose according to your own interests. Japan's infrastructure is perfect. Walking on the road, there is a question mark in your mind and you will see the road sign. Carry a map with you and ask passers-by. This is more reliable than the mobile phone map.
