how about a hair cut in Japan?

[JerseyBoy]

Talking about the hair cut, how do you select the good barber/hair stylist? Good barbers/hair stylists often suggest the better way to cut if the customer is now sure of the style for the particular part of the head.
I went once to a barber near my home in the western Japan and he did a good job. Now that I am living in Tokyo, I (as a guy) am looking for a good barber or hair salon.
