Japanese officials are training to tackle a possible outbreak of mosquito-borne viral infections, ahead of the 2020 Tokyo Olympics and Paralympics.
About 160 officials from the Tokyo Metropolitan Government, the Environment Ministry and other bodies took part in a drill on Monday in Shinjuku Gyoen National Garden in central Tokyo.
The Russian Defense Ministry's newspaper says the military fired new surface-to-ship missiles in a drill last autumn on one of the four Russian-controlled islands that Japan claims.
Krasnaya Zvezda reported on Wednesday that a missile unit belonging to the Russian Pacific Fleet conducted the exercise on Etorofu Island with the Bal system.
A counterterrorism drill with an emphasis on providing guidance in foreign languages has been held at Tokyo's Haneda airport in the lead up to the Tokyo Olympic and Paralympic Games next year.
The drill was held on Wednesday at two railway stations that directly service the airport's international passenger terminal. About 250 people, including railway officials and police officers, took part.
Foreign residents in Sapporo in Japan's northernmost prefecture of Hokkaido have taken part in a drill to learn how they should act in the event of an earthquake or a fire.
Hokkaido was hit by a powerful earthquake last month. The disaster highlighted the need for special assistance for foreign residents who are not familiar with earthquakes.
