Obama Begins Japan Visit
U.S. President Barack Obama arrived in Tokyo Friday, as the two allies looked to put strained security ties behind them.
Tokyo is Obama's first stop on a nine-day Asian trip, and a strong start with new Prime Minister Yukio Hatoyama would set a positive tone for the region.
Hatoyama had pledged to steer a course less dependent on its long-time ally, and ties have been frayed by a row over relocation of a U.S. marine base.
Some Japan-watchers say despite the words, Hatoyama will aim to reaffirm the relationship, with eyes on China's growing diplomatic and financial power.
Obama will stay one full day in Tokyo and three days in China.
The American and Japanese leaders are expected to agree to cooperate on fighting global warming and promoting nuclear disarmament.
Both Obama and Hatoyama will leave Japan on the weekend to attend an APEC leaders meeting in Singapore from Sunday.
