Delegates from Ukraine's public broadcaster have been learning how to archive films properly at NHK's facility in Japan.

The Ukrainian broadcaster was founded in 2017 by integrating a state-run television and regional broadcasters. It has more than 30,000 films that recorded the history and culture of the country.

The broadcaster is concerned that those films may be lost in a Russian attack. A TV tower in the Ukrainian capital Kyiv was hit in such an attack.

Fifteen Ukrainian people, including the head of the broadcaster's archive section, arrived in Japan last week. The Japan International Cooperation Agency, or JICA, and others mediated their visit to Japan.

On Thursday, the group visited the NHK Archives in Kawaguchi City in Saitama Prefecture, near Tokyo, to take part in a training program on how to conserve video content.

They learned how to categorize films based on its content, and grasped that films can be conserved for a long time by maintaining a constant level of temperature, humidity and better ventilation at places where they are stored.

Taisiia Turchyn, head of archive at the Ukrainian broadcaster, said that she realized how important it is to conserve films as they are proof of what existed in Ukraine, as none knows when and what are destroyed in the Russian invasion. She added that she wants to put into practice what she has learned in Japan.

The Ukrainian delegation is scheduled to take part in training sessions at NHK through February 6.
