Before the sixth and final throw, the Swedish star got the audience going, entered the throwing circle and sent off his longest throw of the season, 70.47.
Then he stepped a few meters to the side and waited.
When Mykolas Alekna, Lithuania, did not make a valid throw - then it burst for the 33-year-old.
He screamed out his joy, sprinted across the grass and climbed up to coach Staffan Jönsson in the stands. The hug was not still. Together they jumped for joy of gold.
"Incredibly proud"
I have dreamed of this since I was eight years old, to win at least three World Championship golds and one Olympic Games gold - which Mats Sundin also did, my idol - and I am incredibly proud, says Ståhl.
With the success in Tokyo, he defended his World Championship title from Budapest 2023 - where he also decided with his last throw in the final.
Additionally, the Swede showed that he thrives on the National Arena. It was namely here he won the Olympic Games gold in 2021.
The final in Japan was, however, not like any other.
The rain poured down over the National Arena in Tokyo - and stopped the World Championship final in discus. Daniel Ståhl & Co initially tried to defend themselves against the wetness with umbrellas and rain jackets but in the end, all were forced to seek better shelter and left the infield.
After a half-hour break, the discus throwers were back - only to return to the arena's interior ten minutes later.
The final was underway again almost two hours later than the planned start - despite continued precipitation.
Athletics is such a sport where it can take time, there can be delays, there can be rain. I was prepared for it to rain for a long time. In the forecast, it said two hours, but I thought twelve.
It was just to keep the discus dry and focus extremely hard.
"Reversed irony"
Maria Alberto Diaz, Cuba, slipped in the throwing circle just like German Henrik Janssen and it went worst for Lukas Weisshaidinger, Austria, who landed flat on his back.
Ståhl was, however, just as happy after as before the break. He wrapped towels around his hands and offered dance and laughter.
The Swede ignited the audience during his last three throws in the final, got energy from the atmosphere on the now sparse arena - when everything else was over at that time and the throwers got all the attention - and secured the gold with 70.47.
There's a thing about great Håkan Södergren. It was the World Championship in Russia, he was team captain and said that in Russia it can rain, be dark and have bad locker rooms... The reversed irony. To build up joy and alertness, says Ståhl.
I thought about it today. If it rains - then it's beautiful weather. We go out and have fun, turn on the grill and just eat in the rain.
Alex Rose, Samoa, took bronze with a throw of 66.96.
