The organizing committee of the Tokyo Olympic and Paralympic Games and International Olympic Committee said Tuesday that the delivery of the games remains "firmly on track" a day before the 2020 countdown hits the one-year mark.

"One year to go. The excitement is growing here," said John Coates, chairman of the IOC's Coordination Commission, at a press conference concluding the 10th project review meeting between the two committees.

"You've seen the unprecedented level of interest in ticket sales with 3.2 million tickets sold in the first phase. We've had over 200,000 people apply for 80,000 volunteer positions. You have the contribution from people all over the country, close to 80,000 tons of used mobile phones and electronic devices for production of the medals."

"We're very pleased that the delivery of the games remains firmly on track."

The two-day project review meeting in Tokyo touched on long-standing concerns about heat, transportation and sustainability, with Coates saying organizers have shifted into operation mode as the first major phase of test events kicked off late last month.

The committees said they have already gained valuable insight from the dress rehearsals, which run until next May, and will be able to make crucial adjustments ahead of the Olympics.

"We're learning from the test events," Coates said. "(At the weight lifting event on July 6-7) it was identified that the scoreboard behind the weight lifters was not large enough, so that's been fixed. It was identified that the viewing from the first row of seats wasn't good, so that's been addressed."

"There's little things that each of the federations will raise, be addressed, and we'll make sure that everything's 100 percent for the games."

Both committees have been surprised with the local turnout at the unpublicized trial runs, signifying a growing interest with nearly one year to go until the Olympic opening ceremony on July 24, 2020.

Spectators dotted the course of Sunday's road cycling dress rehearsal that begins in Tokyo and ends at Fuji International Speedway in Shizuoka Prefecture.

"That was very pleasing because it was not an event that was publicized, but there was a significant amount of locals who just turned up to have a look," Coates said.

Yoshiro Mori, president of the Tokyo Olympic and Paralympic organizing committee, said he could feel the local excitement building for the next Summer Games at the events he attended over the past several days.

"There weren't any announcements or advertisements for Sunday's road race, but so many people came out to cheer on the athletes on the road," Mori said. "Every time the athletes passed by a town or village, the locals had taken care of the road to make sure there were no obstacles."

"It was almost like the real games with the local turnout."

Mori also said they hope to utilize that excitement to build up one of the biggest legacies organizers hope to leave behind, an unprecedented engagement with youth following Tokyo's inclusion of four new sports -- skateboarding, surfing, sport climbing and karate.

"Youth is going to be the center play," Mori said, who mentioned the growing interest among Japanese in street sports that he witnessed at the FISE World Series in Hiroshima the past two years.

"Over 100,000 people came from all over this year with just a little publicity throughout the prefecture. A lot of young people came, and the elementary school kids came with their parents," he said. "That movement has to be incorporated into the Olympics Games.

The Tokyo organizing committee president said he hopes the urban cluster of venues in Tokyo's Ariake district, which aims to create a more relaxed, free atmosphere for the games and beyond, will become a "symbolic area" of the tournament.

The 2020 Tokyo Olympics will be held from July 24 to Aug. 9, followed by the Paralympics from Aug. 25 to Sept. 6.
