Marine transport is used to transport new vehicles to sales distributors in Japan that are located north of Sendai or west of Osaka after being assembled in plants in Gunma. The ratio of new vehicles completed in fiscal 2007 that used marine transport accounted for 43.2%*.
*Based on the number of vehicles leaving the plant. Does not include vehicles destined for overseas markets.

Subaru have pushed for the sharing of joint transportation for new vehicles with other vehicle manufacturers, with the number of vehicles (the total number of vehicles consigned to other manufacturers and those consigned to Subaru) transported in the joint transportation scheme in fiscal 2007 totalling 40. This number is similar to that of the previous year, despite a drop in the total number of vehicles being transported.

The environmental impact of transporting marine freight containers can be reduced by increasing the rate at which containers are fully loaded on each round trip and by reducing the total number of trips. Companies using international marine cargo are roughly divided into those focused more on exports (such as Subaru) and those focused more on imports. By predicting the volume of cargo between these companies, the entire transport industry, including smaller transport companies, can reduce its CO2 emissions.
