RIKUZENTAKATA, Japan (AP) — The Japanese coast guard resumed underwater searches this week for some of the more than 2,500 people still missing from the 2011 earthquake and tsunami that devastated the country's northeast coast. "Some people say to me, do you really want to latch onto this forever?" said 81-year old Chikara Yoshida, who lost his only son, a 43-year-old volunteer firefighter who was trying to help elderly residents escape. Yoshida and his daughter led a petition drive through Facebook earlier this year to resume underwater searches. The petition was submitted to Rikuzentakata officials in early March, in hopes that local police would also resume searches. After the disaster, Yoshida heard that his son Toshiyuki had gone to the municipal office immediately after the magnitude-9.0 earthquake to help carry the elderly to higher ground, one by one, before the tsunami came. Mementos of his son remain in the living room: his baseball jacket and cap hang on the wall; a glass of his favorite "shochu," a Japanese liquor, at the family altar; and a large framed certificate from the government acknowledging Toshiyuki's bravery.
