While U.S. President Barack Obama and Japanese Prime Minister Yukio Hatoyama held a summit meeting on Friday, fans and protesters gathered in various locations of Tokyo, trying to draw the attention of the visiting U.S. president.

A group of Obama supporters from Japan’s Obama City didn’t have much of a chance of seeing the president up-close, but that didn’t stop them from making the trip.

The city was Japan's biggest cheerleader of Obama by namesake during his presidential election campaign.

[Seiji Fujiwara, Barack Obama Supporters’ Group, Obama City]:
"We're really hoping that we'll meet him, but it will be rather difficult in reality. We'll do as much as we can though."

Near the U.S. Embassy, eight survivors of the 1945 atomic bombings and their supporters held a rally, urging President Obama to visit Hiroshima and Nagasaki and to keep pursuing a nuclear-free world.

[Fumiko Hashizmue, Atomic Bomb Survivor]:
"Obama said that he would work to get rid of nuclear weapons. But everyone is saying that they want him to come to Hiroshima and Nagasaki."

Japanese Prime Minister Yukio Hatoyama has promised a 25% reduction in CO2 emissions by 2020, while the U.S. has yet to commit to a concrete number.

While Obama begins his Asian trip in Tokyo, he will spend just 24 hours in the Japanese capital before leaving for the APEC summit.
