The action in Japan begins tomorrow, Saturday 13th September, and runs until 21st September.
Duplantis' fans won't have to wait long to see him in action, as the men's pole vault qualification takes place during the evening session on the 13th. That should be a formality for Mondo, who will surely be back for the Final, during the evening session on Monday 15th.
Many could argue that the Final will be a formality as well, given that Duplantis broke the world record for the 13th time in his career just last month, with a clearance of 6.29m in Budapest, Hungary.
Should the 25-year-old get the gold medal wrapped up, the crowd will expected to be treated to a world record attempt of 6.30m, a height Duplantis has spoken openly about chasing, though he has also talked about his ambition to clear 6.40m.
But the Swede could still be challenged for gold if he is not at his brilliant best. At the end of August, he only managed 6.00m at the Diamond League Final in Zurich, beating Greece's Emmanouil Karalis only by having fewer fouls in the competition.
With a best vault of 6.08m this year, Karalis is by far the best positioned athlete to take gold should two-time Olympic and World Championship gold medallist Duplantis not find his best form.
Sweden's other medal hopes
Duplantis is not the be-all-and-end-all when it comes to Swedish medal hopes in Tokyo over the coming days. He is one of a 35-person team taking part in 28 different events across both genders.
At the 2023 World Championships in Budapest, Sweden finished an impressive 10th in the medal table thanks largely to golds for Mondo and Daniel Stahl, who will be the man to beat again in the men's discus.
Perseus Karlstrom's silver in the 20km race walk was Sweden's other medal in Hungary in 2023, and this time he could the first gold of the Championships, as he battles the heat in the men's 35km, as he searches for a fifth world medal, but just a second over the longer distance.
Staying with throwing events, this year's European indoor silver medallist Wictor Petersson will be hoping for a similar result in the men's shot put.
On the track, Andreas Almgren competes in the 5,000m and 10,000m having set a new European record in the former earlier this summer. Samuel Pihlstrom will be competing in the 1500m, a distance he set a new Swedish record over this year.
On the women's side, European indoor bronze medallist from this year, Engla Nilsson, will be hoping for a strong performance in the high jump, while former world and European U20 gold medallist Maja Askag is aiming for her first global senior titles in both the long and triple jumps.
