Torchbearers for the 2020 Tokyo Olympics will pass through all 47 prefectures across Japan over 121 days that will include areas devastated by natural disasters as well as World Heritage sites.

The organizing committee for the Tokyo Olympics announced details about the torch relay on June 1.

The relay will start on March 26, 2020, at the J-Village sporting complex in Fukushima Prefecture and conclude on July 24, 2020, at the New National Stadium in Tokyo where the Opening Ceremony will be held.

The flame will pass through 857 municipalities, about half of all cities, towns and villages in Japan. About 10,000 individuals are expected to carry the torch, although the number of runners to be filled by the sponsors has not been made public.

Corporate sponsors of the torch relay as well as prefectural governments will be accepting applications for relay runners from mid-June until the end of August.

The 47 prefectural governments decided on what areas the torch will pass through in accordance with guidelines established by the organizing committee, such as reinforcing the theme of the Tokyo Olympics as being about reconstruction from natural disasters as well as expressing various aspects of Japanese culture and nature.

In keeping with the reconstruction theme, the torch will pass by the "miracle pine tree" in Rikuzentakata, Iwate Prefecture, that was the only one left standing on a beach after the 2011 tsunami triggered by the Great East Japan Earthquake. While the tree eventually died because its roots were poisoned by seawater, a memorial tree was erected in 2013.

The torch relay will also pass by Kumamoto Castle, which suffered extensive damage from the 2016 series of earthquakes in Kumamoto Prefecture in southern Kyushu.

Among the World Heritage sites that will stand in the background as the Olympic torchbearer passes by are Mount Fuji and Himeji Castle in Hyogo Prefecture.

The prefectural governments will further hammer out the exact roads over which relay runners will carry the torch, and the course should be finalized by the end of the year.

Those interested in carrying the torch will have to be at least in junior high school as of April 1, 2020. They can apply to prefectures with which they have some tie.

The four corporate sponsors will begin accepting applications from June, while the prefectural governments are expected to do so from July. While an individual will have up to five chances to submit applications, they will only be allowed to run a single leg. No politicians will be allowed to run.

Prefectural governments can decide on up to 22 runners a day, and at least half that number will be filled through the applications.

Between 80 to 90 runners a day will carry the torch, with each jogging for about 200 meters.

The other places in the relay will be filled by recommendations made by the International Olympic Committee and corporate sponsors for the Tokyo Olympics. However, the exact numbers to be filled by those recommendations have not been made public.

Successful applicants will be notified by the end of the year. They will have to pay for their transportation and lodging, but they will receive the official uniform, which was also unveiled on June 1.

The white shirt is designed with a red sash placed diagonally over the chest. The sash is reminiscent of the one passed on instead of a baton by runners in the "ekiden" long-distance relay races that are popular in Japan.

Daisuke Obana, the fashion designer who oversaw the uniform, said the sash was intended to serve as a symbol linking the thoughts of people around the world.

The uniform will be manufactured with the sustainable development of society in mind. Coca-Cola (Japan) Co., a sponsor of the torch relay, will provide plastic from recycled bottles so that 15 percent of the material for the uniform is made up of it.
