The Tosaden Kotsu streetcar / tram system in Kochi Prefecture, which was inaugurated in 1904, has the longest history of all Japanese tram systems. Its east-west and south-north lines lie crosswise, which is unique in Japan. Its total stretch is 25.3 km, the longest of all streetcar / tram systems across Japan. The shortest distance between neighboring stops is only 63 meters, less than anywhere else in the country. The “Okyaku Densha” (guest car) is especially popular; it is a carriage in which a drinking party can be held. A one-day travel pass, which is convenient for sightseeing, is sold on Tosaden Kotsu streetcars / trams.
