Authorities in Hokkaido Prefecture in northern Japan will destroy about 150,000 chickens on a local farm due to an outbreak of bird flu, Kyodo reports.

According to the agency, authorities will also conduct an inspection to determine the causes of the infection in the region.

In April, Japan's Hokkaido Prefecture reported a bird flu outbreak at a poultry farm in the Japanese city of Shiraoi.

About 1.8 million chickens have been killed in Japan this season.
