After losing his wife and three children in a massive earthquake that struck the Noto Peninsula a year ago, Keisuke Oma is desperately trying to move forward.

"My wife and children fell victim (to the disaster), but (they) kept me alive," said Oma, 42, an officer of the Ishikawa Prefectural Police Department. "I'm not only living my life, but also living my family's lives," added the resident of Kanazawa, the prefectural capital.

His wife, Haruka, 38, the couple's daughter, Yuka, 11, their first son, Taisuke, 9, and their second son, Sosuke, 3, were at the home of Haruka's parents in the city of Suzu when the 7.6 magnitude jolt hit the Noto Peninsula on Jan. 1 this year.
