All of the venues being built or refurbished for Tokyo 2020 are on schedule, including the centrepiece National Stadium.
The elegant Tokyo Aquatics Centre, which will host swimming and diving at the Games, is 90 per cent complete, according to the Tokyo Metropolitan Government (TMG), and is on schedule to be finished at the end of February.
Likewise, the venue for volleyball and wheelchair basketball is 98% finished with only the painting of the interior floor to be concluded.
"What is left to be done is to finish some of the interior and exterior roof, as well as some office equipment for inside the building," Daishu Tone, venue director for the Aquatics Centre Daishu Tone, said on Thursday.
"Everything will be completed by February next year.”
The Games are set to run from July 24 to August 9.
A feature running throughout many of the Tokyo 2020 venues is the use of wood.
Ariake Arena, the volleyball venue, features 880 cubic meters of wood, mainly sourced from Japan, which is the most of any of the sites other than the National Stadium.
After the Tokyo 2020 Games are over, the arena will be used for concerts and other cultural events.
