Sunday's four games - including the Pool A showdown between hosts Japan and Scotland - are under review
Rugby World Cup organisers on Thursday cancelled England's game against France and New Zealand's clash with Italy as Super Typhoon Hagibis bears down on Japan.
"We've taken the very difficult decision to cancel certain matches in the affected areas," tournament director Alan Gilpin said, announcing the unprecedented step.
Both games were due to be played on Saturday. Gilpin said Sunday's four games - including the Pool A showdown between hosts Japan and Scotland - were under review.
"We are continuing to review Sunday's matches and making every effort to ensure they will be played as schedule," he said.
Hagibis is ranked as "violent", the highest classification used by the Japanese Meteorological Agency (JMA), and is packing maximum gusts of up to 270 kilometres (168 miles) per hour.
