President Barack Obama visited Japan to pay respect in Hiroshima on Friday, and he is the first American president who paid tribute since the bombing.

Obama's visit to Japan marked history and caught the attention of people around the world because the two nations' leaders have dealt with the aftermath of Hiroshima bombing.

One of the survivors of the devastating bombing is Tamiko Shiraishi, a 77-year-old woman. She finds the decision of U.S. to drop atomic bomb on the city as a last attempt to push Japan to surrender. For her, it became a way to end a prolonged battle.

"Had Japan surrendered a little sooner, America wouldn't have had to drop the bomb - Japan kept fighting, even though it knew it was destined to lose. It even lied to its citizens and told them their country was doing well," Shiraishi, told Japan Times

When she was asked by JT whether she thinks the bombing played a big role to end the war, she said "yes."

Yoshiko Kajimoto, now 85, is also a survivor of atomic bombing. She was a 14-year-old schoolgirl way back in 1945. Kajimoto was working at an aircraft parts factory just near her home in Hiroshima when the bomb struck.

"I saw a very bright blue light go across the window of the building. I went underneath the machine and covered my eyes and ears," Kajimoto said in a report by ABC.

"For a moment I imagined my family's faces and thought I would die there," she added

Although some of the survivors seem moved on from the tragic, there were protesters marched through the streets of Tokyo ahead Obama's visit. Japanese protesters gathered in front of Hiroshima Peace Memorial, and they carried a banner with the slogan that reads, "You're not welcome here, Obama," CCTV reports.
