Thousands of troops deployed after Japan's deadly typhoon

It was time to clean up in Tokyo on Sunday (October 13) after Japan's worst typhoon in more than 60 years swept out to sea - leaving behind blue skies and a trail of destruction.

Some 27,000 members of Japan's self-defense forces and rescue workers were sent to save residents stranded by Typhoon Hagibis in the central Nagano prefecture and elsewhere, the government said.

The storm has left large swathes of low lying land in central and eastern Japan underwater, has cut power to almost half a million homes, and has killed at least 18 people, with another 13 missing.

Prime Minister Shinzo Abe has offered his condolences to the families of those killed and said the government was working to save people's lives and property.

Hagibis, which means "speed" in the Philippine language Tagalog, made landfall on Japan's main island of Honshu on Saturday evening (October 12) and headed out to sea early on Sunday.

Authorities have lifted rain warnings for the Kanto region around Tokyo but warned there was still a risk of rivers in eastern Japan overflowing and inflicting fresh damage.
