A tsunami-tossed boat tossed by giant waves lies atop a building in the city of Otsuchi in northern Japan on May 7, 2011.
The day after the earthquake struck, Mayama was in the city of Yamato documenting the destruction when a woman approached him and led him to the mangled wreck of a car where her dead daughter was trapped.
Despite the devastation around them and no help in sight, she and her husband couldn't leave, and she continued to brush the girl's hair with a comb. "I could see only the hair," Mayama said. "She said it's my daughter, it's my daughter."
The woman explained that she had approached Mayama because she wanted him to take pictures to document their loss. "I've never forgotten that," Mayama said.
One year later, Mayama said he is still searching for the woman so he can give her the photographs.
