Taichi Sugiyama was 3 years old when he lost his father, Yoichi Sugiyama, on Sept. 11, 2001. Now 16 years old, Sugiyama came to New York to ask the world to "never forget."

On Thursday, Sugiyama read aloud names of some of the victims of the 9/11 terrorist attacks from a podium at the annual memorial ceremony. Afterward, he added a personal message.

"Dad, thank you for always being there with us, please stay (by) our side forever," Sugiyama said looking skyward.
