Tokyo Metro has announced new Metro Card will be issued from April 22, 2014 for travelers and for the people living out side of the Tokyo Metropolitan area. Those tickets are available for 1 day (800 yen), 2 days (1,200 yen) and 3 days (1,500 yen).
They have not forgotten kids as well; 1 day (400 yen), 2 days (600 yen) and 3 days (750 yen).

And Toei Streetcar (Toden) Arakawa line which operates in northern and eastern Tokyo outside the main tourist areas. The terminus at Minowabashi is near the historical site of Edo's red-light district Yoshiwara which features a completely covered shopping street, several blocks long, in the once common "Ameyoko" style (a shōtengai). Those can nowadays only be seen in Tokyo's outlying neighborhoods.
