Tokyo is making history as the first city to host the summer Paralympic Games for a second time, having also done so in 1964.
With 4,350 athletes competing across 22 different sports - including two new ones - in 539 events, Tokyo 2020 promises to be the biggest Paralympics yet.
A total of 162 delegations, three more than Rio 2016, are taking part, and five countries – Bhutan, Grenada, Maldives, Paraguay and St Vincent and the Grenadines – are making their debuts as part of these Games.
But where did the word “Paralympic” come from, and what exactly does it mean?
Here is everything you need to know.
Why is it called the Paralympics?
Originally, the word Paralympic was intended as a portmanteau - that is, a blend of two separate words to form a new word - combining "paraplegic" and "Olympic".
This is because of the Games’ origins as a sports competition for British World War II veteran patients with spinal cord injuries.
The first athletic event for disabled athletes that coincided with the Olympic Games took place on the day of the opening of the 1948 Summer Olympics in London.
Organised by Dr. Ludwig Guttmann, a German-British neurologist at Stoke Mandeville Hospital, these events were officially known as the International Wheelchair Games.
It wasn’t until 12 years later that the first “official” Paralympic Games were held in Rome in 1960
By this time, the inclusion of other disability groups meant that the Paralympic portmanteau was no longer considered very accurate,
So the present formal explanation for the name is that it derives from the Greek “pará”, meaning "beside" or "alongside", and refers to a competition held in parallel with the Olympic Games.
Though the first official Paralympic Games are widely recognised as having taken place in 1960, the Summer Games of 1988 held in Seoul was the first time the “Paralympic” term came into official use.
What does the logo mean?
The symbol for the Paralympics contains three colours: red, blue, and green. These are the colours which are most widely represented in the flags of the nations of the world.
The colours are each in the shape of an “Agito”, an asymmetrical crescent specially designed for the Paralympic movement.
The Agito takes its name from Latin, and means "I move / I shake / I stir".)
The three Agitos circle a central point, which is a symbol for the athletes congregating from all points of the globe.
