If you are a ramen lover, joining a guided tour might be a good option. Brian, an American guy living in Tokyo, has organized ramen tours for a long time and has a good reputation. After I met him in Shinjuku, I visited a ramen restaurant which he recommended. “Nagi” serves fine ramen with niboshi, a kind of dried sardine. It was fantastic!
We Tokyo Backstreets Bike Tour have bike tours in the north part of Tokyo, including Asakusa, Yanaka, but if you wish to see rather the west, you can join the DIG TOKYO TOURS. This tour is operated by Andy, Australian guy. He has been in Japan so long time so that he knows the backstreets of this area as well as streetfoods. His base is located near the Koenji railway station, where young people love to live because there are a lot of lovely second-hand clothes shops, Izakaya bars, restaurants and so on.
This area is sometimes called “City of rock music”, because there are a few live houses. If you dream to be a Japanese rock star, it might be ideal place to live!
