The Japan rugby team were forced to wade through a flooded Prince Chichibu Stadium in Tokyo ahead training on Saturday morning.
The hosts are preparing for their crunch clash with Scotland in which victory will see them top Pool A and progress to the last eight.
Emerging for training a day ahead of their match, the Japan team faced knee-high water at the bottom of a flight of stairs leading from their dressing room to the pitch.
Footage captured by the Japan Rugby Football Union showed players trying to avoid the water by clambering onto benches which lined the tunnel out to the rugby field. Others piggy-backed team-mates, while some just charged through the water.
Typhoon Hagibis has already arrived in Tokyo - but the worst is yet to come - with England's meeting with France and New Zealand's final pool game against Italy cancelled by World Rugby.
Scotland, who will likely crash out of the World Cup if there game suffers the same fate, are determined to play their do-or-die game with the hosts. Scottish Rugby Union chief executive Mark Dodson has said they will consider legal action to ensure the game is played.
World Rugby says it aims to make a decision on whether Scotland's storm-threatened clash with Japan on Sunday can go ahead as early as possible.
A final decision on whether the game goes ahead must be made no later than six hours before the 7.45pm (11.45am BST) kick-off time.
