An unusually violent typhoon has hit southern Japan with strong squalls and heavy rain.

Thousands of residents had to seek shelter from the storms, and train and air traffic was affected.

On Sunday evening (local time), the 14th typhoon of the season made landfall on the southwestern main island of Kyushu near the city of Kagoshima, the national weather agency announced.

The Japanese television station NHK reported isolated injuries, but there were initially no reports of major damage or fatalities.

The weather agency warned of the danger of "unprecedented" strong gusts of wind, high waves and landslides as a result of the heavy rainfall.

Residents of affected regions were called upon to get to safety in good time.

The weather authority had previously issued the highest typhoon warning for Kagoshima Prefecture, which is located on Kyushu and was particularly hard hit.

Thousands went to emergency shelters there on Sunday, including in neighboring Miyazaki Prefecture.

Tens of thousands of homes across Kyushu temporarily lost power.

The slowly moving hurricane is likely to head northeast after the long weekend due to the holiday and also cause heavy rain on the main island of Honshu with the capital Tokyo.
