Tokyo plans to spend ¥45.2 billion on fuel-cell vehicle subsidies and hydrogen stations for the 2020 Olympics as part of Prime Minister Shinzo Abe's plan to reduce the nation's reliance on nuclear power.

Thirty-five hydrogen fuel stations will be built in the capital, which is in negotiations with Toyota Motor Corp. and Honda Motor Co. to put 6,000 hydrogen cars on its roads by 2020, said Makoto Fujimoto, who heads the planning team at the metropolitan government's energy department.

The nation is investing in hydrogen power as it continues to struggle with the aftermath of its worst peacetime nuclear disaster, in 2011. Spending on hydrogen infrastructure comes as Tokyo's government is under pressure to rein in costs as it prepares to host the quadrennial games.
