 The Port of Shimizu is also connected to other Japan ports.In particular, it is served by a Roll-on/roll-off service serving the port of Ōita, on the north-east coast of the southern island of Kyushu.This service, which sails three times a week and has a transit time of 20 hours, has enabled a modal shift of freight trucks from road to sea, thereby contributing to decreasing congestion and pollution on roads.
