Ukrainian police officers who have been concluding their Japan visit say they hope to utilize what they learned in Japan to identify victims of Russia's invasion of their country.

The ten-member national police delegation is comprised of identification experts.

They visited Fukushima Prefecture to hear from police officers there who worked to identify a huge number of victims from the 2011 massive earthquake and tsunami.

The delegation led by Oleksandr Shulha met reporters on Friday. Shulha said at least 3,500 victims have not been identified in Ukraine, as missile explosions had severely damaged their bodies.

Shulha said the members learned how Japanese police found victims among rubbles and identified them.

He expressed hope to understand more about DNA and fingerprint databases Japanese police have been operating for identification.

Fukushima prefectural police officer Abe Katsuya said the delegation members said they wanted to learn more about Japanese police know-how and techniques to identify bodies.

He said they will continue to respond to requests from Ukraine.
