Five years after the Great East Japan Earthquake, police in Fukushima, Miyagi and Iwate prefectures are still searching for and identifying the bodies of those who went missing on March 11, 2011, though as time goes on they have fewer clues to work with.

The huge earthquake and ensuing tsunami caused massive damage across a broad swath of the Tohoku region. It left a total of 15,894 people dead, while 2,562 people remain unaccounted for as of Feb. 10, including 1,124 in Iwate, 1,237 in Miyagi and 197 in Fukushima, according to the National Police Agency.

Authorities in the three prefectures say they had recovered the bodies of 4,672 in Iwate, 9,539 in Miyagi and 1,613 in Fukushima by the end of January. The figures exclude the number of headless bodies, remains with only parts of the body recovered, as well as victims of aftershocks from the March 11 quake.
