As an experience, Tokyo will be more polished, more high-tech and more intense than anything we have witnessed in Rio.
The Japanese capital is one of the most energetic and pulsating places on earth – and organisers are already hard at work to make the Games reflect this.
The addition of several new and exciting sports – like surfing, skateboarding and climbing – to the Olympic programme will no doubt help in this regard, too.
Many of the arenas are already in place, although there has been some controversy over the design and construction of the new Olympic stadium.
There is also an investigation into controversial payments made to officials linked to Tokyo’s bid, while the first official logo for the 2020 Games had to be scrapped after claims of plagiarism.
“One thing we won’t have to worry about in Tokyo is there isn’t a lot of crime,” Japan Times journalist Jake Adelstein told BBC Radio 5 live.
“Tokyo is ready to handle loads of tourists and it’s a very safe city. How they’ll deal with the heat is the question that is up in the air.
“When Japan submitted their bid for the Olympics, they wrote that the mild weather will provide athletes with conditions to perform at their best.
“But Tokyo, at this time of year, is anywhere between 30 and 40 degrees, with humidity at 80%, so if you feel that being on the inside of a sumo wrestler’s armpit is the ideal way to perform at your peak, then Tokyo is the place to be.”
