The 2020 Olympics will take on a radical new look, with its urban sports venues to be open for public use while the games are in progress, International Olympic Committee Vice President John Coates said Wednesday.

Earlier this month, the IOC decided to add 15 events to Tokyo to bring the total to 339 including 18 from the game's five new sports -- baseball/softball, karate, skateboarding, sport climbing and surfing.

Following an IOC Coordination Commission visit of the Aomi urban sports venue Wednesday, Coates, who chairs the commission, said fans will have an opportunity to actually use the venues themselves during the Olympics for sports such as skateboard, sport climbing and the BMX freestyle.

It would be the first time a competition venue will be opened up for public use during the period of the games.

"We're very pleased with this," Coates said following the inspection at Aomi, where skateboarding, sport climbing and five-a-side football in the Paralympics are set to be held in 2020.

"As you know, we have introduced on your recommendation the new sports of sports climbing, skateboarding and surfing. And then recently, in cycling we've introduced BMX freestyle and with these sports what we want to do is bring them to the people, have them available to the people of Tokyo."

"There will be competitions and then say in the afternoon, children can access and have a go at themselves. They're all sports that, as you can see, engage with young people. In terms of our vision and Tokyo 2020's vision of wanting to bring these sports to the people, I think this is a good location."

Coates said the meetings in the morning that kicked off the commission's three-day visit were productive.

The Australian added that "tremendous progress" had been made since the commission last met in December, when the Tokyo Olympic stakeholders -- the organizing committee, the Japanese central government and the Tokyo metropolitan government -- were still locking horns about the games' overall budget.

"We are very pleased to receive a report this morning on the allocation of role and responsibilities of the parties to the organization of the games and the allocation of costs," Coates said.

"With three years to go, we're very, very pleased. It was a critical step along the way for the organizing committee, the national government and the Tokyo municipal government to, amongst themselves, decide who's responsible for what and who's paying for what."

"That's happened and we still think there's opportunities to make further savings."

During his opening address to the commission, Coates said he wanted to decide on the venues for the urban sports this week.

"...Hopefully (we) are very close to settling the location of these new urban sports. It's important that we finalize where skateboarding, the sport climbing, BMX freestyle, the 3-on-3 basketball and other competitions (are held)."

"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."

Coates also said the commission will be out to settle the number of baseball and softball games that will be played in Fukushima.

"We need to finalize how many games in baseball and softball go to Fukushima," Coates said. "We really want to honor 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 March 11, 2011, earthquake and tsunami)."

Also on the agenda will be the Olympic lane that will connect the Olympic Park to the athletes village and the IOC hotels.

The original construction plan of the No. 2 ring road that the lane will be on has been sent back to the drawing board after Tokyo Gov. Yuriko Koike delayed her decision on the relocation of the Tsukiji fish market until last week.

Part of the road was supposed to pass through a yet-to-be-built tunnel beneath Tsukiji. But for the tunnel to be built in time for the games, Koike needed to decide on Tsukiji by March and now the tunnel is no longer an option.

While Koike has said the road will be complete, she has not said how it will be finished. Tokyo's chief organizer Yoshiro Mori on Wednesday pressed Koike for details.

"For Tokyo 2020 to be a success, the transport of athletes, officials and fans will be a huge key," Mori said. "Last week, Gov. Koike said the all-too-important No. 2 ring road that will link the athletes village and the new National Stadium in 10 minutes would be complete."

"But the initial plan to build a tunnel has had to be scrapped, and no details on how the road will be finished have been offered. If the road is not built in time, not only will it affect the transport of the games but will critically impact the people who live in the area and the fundamental functions of the city."
