Tokyo Olympic organisers said Wednesday that prolonged summer rain had temporarily brought high levels of bacteria to a venue intended for triathlon and marathon swimming at the 2020 Games.

The admission came during a visit by International Olympic Committee officials to assess Tokyo's readiness to host the Games, with just a little over 1,000 days to go.

Many samples taken from late July through early September at the Odaiba Marine Park showed elevated levels of pollution, particularly following rain.

"The timing and the volume of rainfall impacted the data," said Koji Murofushi, sports director for the Tokyo 2020 organising committee.

Murofushi blamed unusually long rains -- the Japanese capital saw three straight weeks of precipitation at that time -- that brought pollutants from offshore.

Tokyo officials said underwater screens and better infrastructure, including beefed up local sewage, should help maintain the water quality to international standards.

The facility routinely hosts triathlon and swimming events that meet international quality standards, sports officials said.

Low bacteria readings followed sunny or cloudy days, according to organisers.

Murofushi rejected the idea of changing the venue, pledging that "measures will be taken so that we can provide an excellent environment for the sports" during the 2020 Games.

IOC vice president John Coates warned the Japanese capital should prepare for the worst possible weather conditions.

The IOC expected Tokyo to take steps "to ensure that even in the worst of conditions that those matters will be addressed and the health of athletes in those two sports will not be prejudiced in any way", Coates said.

Swimming's governing body FINA said it will also help Tokyo prepare the best possible venue.

"As the world governing body for Aquatic sports, FINA will keep working closely with the Tokyo Metropolitan government and Tokyo 2020 Organising Committee to ensure the best available venue and environment for the marathon swimming events in 2020," it said.

Organisers of the Rio Olympics in 2016 were left red-faced when the pool used for diving events turned an unsettling shade of green overnight.

Separately, Coates said Tokyo should aim to cut overall costs by $1 billion from the current $12 billion budget, including studying ways to reduce the services at the athletes' village.
