Organisers claim the website has been re-engineered to deliver more information about the preparations for the 2020 Games, the Olympic and Paralympic Movements, and the sports and venues.

It is said to fulfil the needs of the modern digital and mobile era in a user-friendly manner, having been adapted for a diverse array of platforms and devices.

Available in three languages - French, English and Japanese - the new website allows users to directly share their interests with others on social media.

It also features a new "Get Involved" section to engage people from across Japan and the world in the creation and delivery of the Games.

The website is said to reflect  commitment by Tokyo 2020 to accessibility by being optimised for a wide range of impairments and offering universally-accessible contents.

It aims to comply with the AA class of the 2010 version of the Japanese Industrial Standard JIS X 8341-3, developed by Japan’s Web Accessibility Infrastructure Committee.

Hackers targeted Tokyo 2020's website in November, causing it to crash for several hours.

An attempt was made to overwhelm the site with traffic, a situation Tokyo 2020 director general Toshirō Mutō described as an "extremely serious issue".

Japan's Government has since announced it intends to increase the number of exercises it holds in the battle against cyber attacks in the lead-up to Tokyo 2020. 

Drills aimed at countering hackers are usually held six-times a year, but this will be increased to 10, according to the Japan Times.

Despite a series of setbacks and issues, including the plagiarism row over the original emblem for the Games and concerns about the new National Stadium, the International Olympic Committee (IOC) last month declared that they "couldn’t be happier" with Tokyo 2020’s preparations.

"For a city that's four years out to the Games, I don't think we've ever seen a city more prepared," said IOC vice-president John Coates.
