Prime minister Fumio Kishida called for urgent action from ministers while prioritising public safety.

“Please continue to put people’s safety first and cooperate closely with local authorities to take all possible measures to keep the public informed, support evacuation in advance in areas where danger is anticipated, and maintain a well-prepared disaster response centred on the police, fire department, and Self-Defense Forces,” he said at a meeting, according to the Japan Times.

A Level 4 warning for heavy rainfall has been announced in Mie Prefecture, and the Kanto region is also on alert for similar weather.

Residents in Mie and Kanto Prefectures, as well as the prefectures of Yamanashi, Nagano and Niigata have been warned to stay alert for landslides and flooding.

The storm, according to the weather agency, is moving southeast at about 15 kph, with wind speeds going up to 65 kph and gusts reaching up to 90 kph.

Some parts of Japan, especially Kyushu, were seeing mobile network issues due to Shanshan.

Residents in some parts of Nagasaki, Kumamoto, Oita, Miyazaki and Kagoshima using Softbank did not have a mobile signal on Saturday, caused by power outage or structural damage to their networks, reported Japan Times.

Residents who use NTT Docomo also reported similar failures in Kumamoto, Miyazaki, Oita and Kagoshima.

Shanshan has now been downgraded to a tropical storm, but is still seeing winds of 90kph.

Gifu and Mie prefectures saw heavy rain, and the meteorological agency has warned people to “remain vigilant for landslides, flooding and overflowing rivers”.

“This is the first time I saw a typhoon sweeping across all of Japan,” a resident in the capital, Tokyo, told Reuters.

“Typhoons are supposed to go north from Okinawa. So, I didn’t expect it to be like this. I’m very surprised.”

The storm moved eastward through Japan today, and national broadcaster NHK reported record levels of rainfall, with the storm taking the roof off of several houses and flooding roads in the southwest.

Japan’s Fire and Disaster Management Agency said one person is missing, and more than 100 are injured.

Over 35,000 homes in southern Kyushu’s Kagoshima prefecture have no power, according to Kyushu Electric.

The storm is seeing winds of up to 90kph, and is forecast to weaken to a tropical depression over the weekend.

Heavy rains caused by Typhoon Shanshan are expected to continue in western and eastern Japan, with heavy localised showers forecast on Saturday.

Heavy rain clouds may develop in Tokai, central Japan, through Sunday morning, intensifying chances of further disasters.

The downpours have also heightened the risk of landslides in Iwate, Saitama, Tokyo, Kanagawa, Shizuoka, Mie and Gifu prefectures, and warnings have been issued for some areas.

Parts of the Tokyo, Kanagawa, Saitama, Aichi, Gifu, Shizuoka, Mie and Shiga prefectures remain under evacuation orders.

Footage has shown a plane plane tilting from side to side before being forced to abort its landing in Fukuoka, Japan.
