Ukraine's agricultural officials have expressed hope for more assistance from Japan to rebuild the country's farm sector, which has been battered by the Russian invasion.

Six officials, including Deputy Minister of Agrarian Policy and Food, Markiyan Dmytrasevych, are now visiting Japan. They called on the headquarters of the Japan International Cooperation Agency, or JICA, in Tokyo on Monday.

JICA Vice President Kubota Osamu said he attaches the utmost importance to supporting Ukraine's agriculture, as it is the country's key industry and vital for food security.

Dmytrasevych said he appreciates Japan's ongoing support, which includes assistance to remove landmines.

He said many irrigation facilities mainly in southern Ukraine have been destroyed.

Dmytrasevych said he hopes that incorporating Japan's "smart farming" and irrigation technologies will revive and enhance Ukraine's agriculture. Smart farming utilizes the latest innovations, such as drones.

The Ukrainian officials plan to visit northeastern Japan's Miyagi Prefecture for three days to see how the region's farm sector recovered from the March 2011 earthquake and tsunami disaster.
