Relatives on Thursday formally identified a Japanese couple killed in the Aug. 27 plane crash in Kentucky as Tetsuya Kono, 34, and his wife, Nahoko, 31, Foreign Ministry officials said.

The couple were among the 49 people killed when the Comair jetliner crashed on takeoff in Lexington.

Citing information from the Japanese Consulate General in New Orleans, ministry officials said the relatives confirmed the victims' identities Thursday, after being briefed by U.S. authorities on the results of a postmortem examination.

Kono and his wife had been living in Kentucky, where he worked at LBX Co., a U.S. affiliate of Tokyo-based Sumitomo Construction Machinery Co.

Kono and his wife were on their way to Yosemite National Park in California for their summer vacation.

On Wednesday, six relatives of the couple visited the scene of the crash and released a statement through the Foreign Ministry.

Their statement read: "After watching the crash scene, our grief has grown even larger."

The relatives included Katsuya Kono, Tetsuya's father.
