Spa treatments are so cheap there I also got a regular pedicure, a manicure, a facial, and a hour and half massage!
I didn't have a lot of time but I did manage to eat one of the most amazing (and most expensive) meals of my life eaten with real chopsticks, served by women in kimonos. And I explored a little of the city. Tokyo is the largest and cleanest city, I have ever seen. Unfortunately, my knowledge of head, shoulders, knees, and toes in Japanese didn't serve me well but I hopefully next time Dad will be able to come with me!
