Tokyo Gov. Yuriko Koike said Thursday the metropolitan government will in principle bear all the costs of temporary facilities for the 2020 Olympic and Paralympic Games to be built outside the capital.

Following a meeting with Prime Minister Shinzo Abe, Koike also said the two sides agreed to seek a framework under which the games' organizing committee will shoulder half of the costs for holding the Paralympics, and the other half will be equally shared by the central and Tokyo governments.

The new plan emerged amid reluctance by other local governments to take on the costs of building temporary facilities in their prefectures.

Asked whether Tokyo will shoulder all the costs, Koike said, "Although we are still closely examining everything, we are heading in that direction." The governor added she has asked for a bearing of the financial burden on the state's part.

The costs to build temporary facilities in six prefectures, excluding Tokyo, are now estimated to reach 43.8 billion yen ($385 million). They are likely to expand to around 50 billion yen if spending includes facilities for the events most recently added to the Olympic program, such as baseball and softball.

All the outlays were initially supposed to be covered by the committee, and if the committee's funds fell short, the metropolitan government was supposed to make up for them.

But the plan hit a snag as the estimated costs ballooned, triggering debate over the idea that part of the burden should be shouldered by Tokyo and other local governments.

After hearing Tokyo's decision, Chief Cabinet Secretary Yoshihide Suga welcomed the move, saying he hopes the preparations for the games would make progress.

"The state will cooperate in the greatest extent possible in realizing successful Olympics that will meet the people's expectations," he said.

Kanagawa Gov. Yuji Kuroiwa was not satisfied with Koike's announcement. "It is something we should welcome, but there is still a problem of operational costs," he said.

His prefecture, located southwest of Tokyo, will host sailing in waters off Enoshima island. Kanagawa may need to compensate local fishermen as they will be forced to halt fishing during the event.

Chiba Gov. Kensaku Morita called the decision a "matter of course" but added, "It is great that (Tokyo) kept its promise." Chiba Prefecture, east of Tokyo, will host wrestling and surfing among other games.

"It is understandable that the governor tried to reduce the burden on Tokyo citizens, but we somewhat passed our time limit," said Kiyoshi Ueda, the governor of Saitama Prefecture, north of Tokyo, which will host four sports including soccer and basketball.

While Koike had initially planned to decide how the local governments should share the costs by the end of March, she was met with a backlash from those opposed to shouldering costs. The governor said Tuesday she would make a decision later this month.

On the same day, Abe instructed Olympic minister Tamayo Marukawa to intervene and help resolve the issue after the governors of Kanagawa, Saitama and Chiba called for swiftly setting the outline of the financing plan.

The organizing committee announced in December that the total costs for hosting the 2020 Tokyo Olympic and Paralympic Games are roughly estimated at up to 1.8 trillion yen.

It also called for the national government, the Tokyo metropolitan government and local municipalities to share about 200 billion yen in costs to build temporary facilities in Tokyo and other prefectures.
