At least one person has died in Japan when Typhoon VongFong lashed over the country after making landfall on Kyushu and Shikoku on Monday. The storm, already downgraded, is now headed towards Tokyo.

NHK identified the dead as a 90-year old man who was found in a canal in a field irrigation ditch in Tottori Prefecture. The storm also injured at least 93 people, one of them a U.S. citizen, the Weather Channel reported, citing Fuji TV. The American was a pilot who figured in a light plane crash in Ibusuki city, Kagoshima Prefecture, near the southernmost tip of the main island of Kyushu.

VongFong's ferocious winds that created monstrous waves swept three Chinese fisherman into the Pacific Ocean, national newspaper Asahi Shimbun reported. Two have been rescued while the last remains missing.

On Monday, Tokyo experienced heavy rainfall forcing the shutdown of power supply. VongFong also triggered a massive travel disruption on air and bullet train services that coincided at the end of a three-day national holiday. NHK said over 600 flights on Monday were cancelled nationwide and advised travellers to brace for more cancellations on Tuesday.

VongFong's reach was so wide enough that it also affected the second day of the Busan Cup Women's International Match Race in South Korea. Alfredo Ricci, Regatta Director, said the winds were around 30 knots, "well above the limit," making it impossible to push through with the competition. The race will resume on Tuesday.

VongFong also affected at least five flights to and from Singapore and Japan, the Straits Times said. The affected services to Tokyo, Osaka and Fukuoka were operated by low-cost carriers Jetstar and Scoot.

VongFong, earlier categorized as the strongest typhoon to hit Japan this year, had weakened sharply. As of Tuesday, the Japan Meteorological Agency said it was heading off the coast of the Tohoku region, moving northeast at 65 km per hour (40 miles per hour), heading off the coast of the Tohoku region. Vongfong's present maximum sustained winds are now at 110 kph (70 mph) and gusts up to 145 kph (90 mph), the agency added.

Tohoku region is the site of the crippled Fukushima nuclear power plant. Water transfer and storage capacity has been increased to prevent an overflow of radioactive water being stored at the plant, its operator, Tokyo Electric Power Co, said.

Close to one million people nationwide were affected by the storm as authorities urged them to leave their homes. Over 150,000 homes lost power.
