TOKYO (AFP) - Typhoon Man-yi hit central Japan on Monday as officials issued a "special warning" of heavy rain, amid fears the storm could go on to hit the crippled Fukushima nuclear plant.

The typhoon made landfall in Toyohashi, Aichi prefecture, shortly before 8am (7am Singapore time), packing gusts of up to 162kmh, the Japan Meteorological Agency said.

Public broadcaster NHK said a woman in her 70s was missing following a landslide in Shiga prefecture, while at least six people were injured in other areas due to strong wind.

The typhoon, moving north-northeast at a speed of 45kmh, is expected to head towards the capital and its surrounding region later in the day, the agency said.

The agency issued the highest alert for "possibly unprecedented heavy rain" in Kyoto and its adjacent prefectures, warning residents in danger zones to evacuate to shelters.

About 350 domestic flights scheduled for Monday, a public holiday, were cancelled, mainly those departing Tokyo, and train services were also reduced, NHK reported.

The typhoon was expected to cross the northeast, including the Fukushima area, Monday afternoon possibly bringing heavy rain to areas near the crippled nuclear power plant, according to its predicted track.

Crews have struggled to contain the nuclear plant after the March 11, 2011 earthquake and tsunami that triggered the atomic disaster and led to the contamination of groundwater with radioactive materials as it flows to the Pacific Ocean.

With torrential rains expected Monday more contaminated water was feared to seep into the groundwater and workers pumped water from around highly radioactive tanks at the plant.

The typhoon had already brought heavy rain and strong winds to the south and east before even hitting Japan.
