This move is in line with the need to develop charging infrastructure facilities to promote the use of electric-powered vehicles.

The Japanese government has provided around JPY100.5bn ($1.03bn) in subsidies to the alliance. However, the companies have also agreed to invest in the installation of charging units.

These four companies will construct a charging network in partnership with companies providing charging services in which each of the four automakers already have a financial stake, according to the companies.

Currently, Japan has around 1,700 quick EV chargers and just over 3,000 normal EV chargers.
