Transport around Tokyo
Tokyo has it all and it is easy to discover. Rent a bike, you can get one for as little as 500 yen a day and it is a beautiful way to explore the city. Can even get an electric bike for not too much more! Or jump on the trains and subways they are surprisingly good value and very convenient. Can get a Suica card or Pasmo card and pay as you go or one of the unlimited day passes from about 800 yen a day http://www.japan-guide.com/e/e2017.html
Have also done it on a skateboard combined with the trains and that is lots of fun.
