The torch relay to the 2020 Tokyo Olympics will take around 114 days to reach all of Japan's 47 prefectures, and will place special emphasis on areas affected by the 2011 earthquake-tsunami-nuclear disaster, sources told Kyodo News on Tuesday.

Three northeast Japan prefectures hard-hit by the disaster -- Iwate, Miyagi and Fukushima -- will be allocated three days each, the sources said. Four prefectures outside of Tokyo hosting Olympic events -- Saitama, Chiba, Kanagawa and Shizuoka -- will also get three days each in the relay.

Tokyo will be given 15 days and the other 39 prefectures across Japan two days each, with the total number of days still open to adjustment, the sources said.

The final framework is expected to be approved at a meeting on April 10 between the 2020 organizing committee, the central and Tokyo metropolitan governments and the National Governors' Association.

On Tuesday, Yoshiro Mori, president of the organizing committee, called on Prime Minister Shinzo Abe at his office to brief him on the torch relay plans.

Speaking to reporters later, Mori said only that draft plans have been created, without divulging any specifics on the total days required or how they will be allocated.

Organizers hope to announce the route of the torch relay in the summer of 2019. The lighting of the Olympic torch has been a feature of the modern Olympics since the 1928 Amsterdam Games, while the relay was created by Nazi Germany in 1936 for Berlin.
