A tropical storm is expected to hit Japan on Tuesday, but Olympic organisers are not expecting events to be disrupted.
The surfing finals have been brought forward to Tuesday from Wednesday, while rowing and archery events had already been moved, but there are no plans to move any other events at this stage.
A typhoon had originally been forecast, but the storm has now been downgraded.
BBC Weather’s Matt Taylor said: “A weakening tropical storm Nepartak is approaching Japan, but should make landfall a reasonable distance away from Tokyo, further north and east across Honshu.
