Chiefs of mission from Olympic committees around the world have gathered in Tokyo to attend briefings on preparations for next year's Games.
Representatives from 194 of the 206 Olympic committees set to compete in the Tokyo Games are taking part in the three-day meeting that began on Tuesday.
On the opening day, the Vice Director General of the Tokyo 2020 organizing committee, Yukihiko Nunomura, reported that construction of sports venues is progressing smoothly and on schedule.
The participants later toured the main Olympic stadium and other venues, checking on how the athletes will travel between the locations.
The organizing committee plans to meet separately with all participating representatives to answer questions about topics such as measures to deal with the heat, or the travel time between the athletes' village and various venues.
The mission chief from the Netherlands, Pieter van den Hoogenband, has won three gold medals in swimming. He said he was impressed with the preparations and expressed confidence that the organizing committee will be fully prepared to cope with the summer heat.
