Organizers of the Tokyo Olympics and Paralympics have unveiled a hydrogen torch that will be used in some sections of the torch relay that starts in Fukushima Prefecture on Thursday.
The Tokyo organizing committee is planning to use the torch as part of promotion efforts to make the Games eco-friendly. The hydrogen torch does not emit carbon dioxide.
The committee says the use of such a torch will be the first in Olympic history.
Hydrogen fuel for the torch was produced at the Fukushima Hydrogen Energy Research Field, which opened in the town of Namie in Fukushima Prefecture last March. Its hydrogen production is said to be among the world's largest.
The town was hit hard by the 2011 earthquake and tsunami and after the Fukushima Daiichi nuclear accident, its residents were ordered to evacuate.
Namie is one of the places included in the route for the torch relay in Fukushima. Some runners will also carry the torch in Tokyo, the host city of the Olympics, as well as in Aichi Prefecture.
Toyota Motor which cooperated in the development of the hydrogen torch has its main office in Aichi.
