Dozens of hydrogen stations are expected to be built across the country to pave the way for the advent of fuel cell vehicles, but many of the facilities planned are clustered around a few key cities.
In Aichi Prefecture, construction is underway on seven hydrogen facilities, while most of the other prefectures in the Chubu region have yet to make plans.
With four trial stations already in operation, hydrogen facilities in the prefecture will reach 11 once construction on the new ones is complete.
