The International Olympic Committee (IOC) coordination committee started its latest three-day visit to Japan on Wednesday, with chairman John Coates urging Tokyo organizers to further reduce costs for the 2020 Olympics.
Despite some cost-cutting measures, the estimated cost has doubled to 1.4 trillion yen (12.5 billion dollars) since the Japanese capital won the bid in 2013, according to Tokyo organizers.
Cost-cutting efforts are also important to IOC in order to attract candidate cities for future Olympic games, the IOC vice-president Coates said.
The coordination commission aims to decide this week on the venues of the new urban events being added for the 2020 Games, he said.
"This week, we will and hopefully are very close to settling the location of these new urban sports," said Coates, who heads the commission. "It's important that we finalize where skateboarding, the sport climbing, BMX freestyle, the 3-on-3 basketball and other competitions."
"Once we settle that, we can focus on the sports presentations and spectator experience. The engagement with youth is right at the very top of what we want to do here."
Earlier this month, the IOC decided on the full programme for the 2020 Games, adding 15 events to bring the total to 339 including 18 from the games' five new sports - baseball/softball, karate, skateboarding, sport climbing and surfing.
Coates also wants to settle the number of baseball and softball games in Fukushima, the site of Japan's worst nuclear accident in March 2011, triggered by a powerful earthquake and resulting tsunami.
"We need to finalize how many games in baseball and softball go to Fukushima," Coates said.
"We really want to honour the commitment that President (Thomas) Bach made to Prime Minister (Shinzo) Abe, to take the events to Fukushima as part of the recovery, rehabilitation," from the nuclear disaster, he said.
