The typhoon, which is the worst storm to hit the country in decades, has left at least 37 dead and 20 missing.
Thousands of police officers, fire fighters, coast guard, and military are working to reach those trapped by landslides and floods.
The Prime Minister’s Office of Japan said the rescuers would focus on “houses isolated by floods and search for those unaccounted for”.
Typhoon Hagibis also caused the cancellation of three Rugby World Cup matches, but the key match between Japan and Scotland went ahead.
Japan won 28-21 to reach the quarter-finals for the first time.
Afterwards, national team coach Jamie Joseph said: “Everyone who is suffering with the typhoon, this game was all for you guys. The crowd was massive for us, and today was more than just a game”.
