TOKYO, Nov 13 (Reuters) - U.S. President Barack Obama arrives in Tokyo on Friday for a summit where the two allies will seek to put strained security ties on a firmer footing as they adjust to a rising China set to overtake Japan as the world's No. 2 economy.

Tokyo is the first stop in a nine-day Asian tour that will take Obama to Singapore for an Asia-Pacific summit, to China for talks on climate change and huge trade imbalances and to South Korea where Pyongyang's nuclear ambitions will be in focus.

Washington's relations with Prime Minister Yukio Hatoyama's new government, which has pledged to steer a diplomatic course less dependent on its long-time ally and forge closer ties with Asia, have been frayed by a feud over a U.S. military base.

Obama and Hatoyama, whose Democratic Party ousted its long-dominant rival in a historic August election, were expected to turn down the heat in the dispute over the U.S. Marines' Futenma air base on Japan's southern Okinawa island, a key part of a realignment of the 47,000 U.S. troops in Japan.
