We are halfway through the Tokyo 2021 Olympics, and although no crowds have been allowed inside the venues, spectators can still appreciate the intricate details of the various stadiums. 

Despite costing millions, horror stories often circulate about past Olympic venues lying derelict.

It's a legacy Tokyo are keen to avoid and Japan have already planned how to use the buildings once the games are done. 

Here's how Tokyo's Olympic venues could be used in the future.  

How will Tokyo's Olympic venues be used after the Olympics?

The Olympic village is perhaps the easiest to repurpose, with Tokyo's accommodation set to become residential apartments. 

It aims to "establish a new community where a diverse range of people can interact and live comfortably", however concrete plans for renovation are still in development. 

Ariake Arena was built for the volleyball but post games will become a cultural centre. 

The Aquatics centre is also brand new, and will open to the public after the games conclude next week. 

Many of venues, rather than being built new, have been converted for the Olympics or repurposed from Tokyo's first games in 1964. 

For example, the Nippon Budokan, home of judo for the games, doubles up as Tokyo's most popular rock venue, with artists such as the Beatles and ABBA having  graced the stage.

The main stadium was first built for the 1964 games and will be used for sporting and cultural events following Tokyo 2020. 

What happened to Olympic venues from London, Rio and Beijing?

An overarching theme of the London 2012 games was legacy, which the city seems to have lived up to. 

The bid team was keen to ensure the purpose built venues would provide for the local community after the games. 

To this day, the stadiums are used for both amateur and professional level sport, providing venues for training and international competition. 

London focussed so heavily on this goal due to the failure of past Olympics to build a legacy around the venues. 

Pictures of Beijing's Olympic park shows lakes without water, rusted metal, tracks overgrown and toppled mascots. 

Unfortunately it's a similar story in Rio, where the situation got so bad that in January 2020, the Olympic park was ordered to close over safety concerns.

Even the village didn't convert appropriately, with thousands of apartments left empty following the games.
