The Sumida River flows through Tokyo and is spanned by 26 bridges spaced about a kilometre apart over a distance of 27 km. Waterbuses provide transport along the river and are very popular even though they are a bit slower than the trains. The Asakusa to Hinode Pier route is a favourite with travellers who like to get off at Hamarikyu Garden to enjoy the beautiful Japanese garden. Those who do not wish to explore the river on their own can join one of the many cruises offered by tour operators in the area.
