April 10 (Bloomberg) -- Toyota Motor Corp., the world’s biggest carmaker, aims to improve the energy efficiency at its factory in Japan’s northern Tohoku region by about 20 percent.
The cut in energy use will be achieved with the F-grid, a system to manage the energy use at the factory base in Ohira city, Miyagi, President Akio Toyoda told reporters at the plant today. It also targets reducing carbon dioxide emissions by about 30 percent, he said.
Toyota, which makes a bigger percentage of its cars in Japan compared with Honda Motor Co. and Nissan Motor Co., is improving its third domestic production base to become more self-sufficient and cut risks of energy supply shortages.
“For investments in Japan, we want to look at things in the long term,” Toyoda said.
Toyota built 45 percent of its vehicles in Japan last year, compared with its two closest domestic rivals, which both built about 30 percent of their vehicles in the country.
Shares of Toyota rose 1.1 percent to 5,330 yen at the close in Tokyo trading. They have gained 33 percent this year, helped by the weaker yen.
