It’s hard to believe, but there is the very slim chance that you might run out of activities when you’re in Tokyo.
You will have had to have combed the entire city of 13.96 million people, the 60,000+ restaurants, 6,000 different parks. (see some of our suggestions, below.)
But, if all of that is not enough, watch the video below where Doai Station is located. 70 m underground and the deepest station in Japan, you have to go up 486 steps to get to the exit. Have fun!
