The UIPM, the international modern pentathlon federation, has awarded Tokyo hosting rights to the World Cup final in 2019, which will act as the sport's test event for the 2020 Olympic Games in the Japanese capital.
The event will take place in June, 13 months before the games start, and will allow the Tokyo 2020 organising team to create a "dress rehearsal" for the Olympic Games, the UIPM said.
All five disciplines (fencing, shooting, swimming, riding, and cross-country running) of modern pentathlon will be staged in the same stadium for the first time at an Olympics in Tokyo, with a temporary swimming pool to be installed at Tokyo Stadium.
UIPM President Klaus Schormann said: "Not only am I confident this will be a very well-prepared World Cup Final that lives up to the standard that has been set in recent years, I believe we will also be presented with a clear vision for the wonderful Modern Pentathlon that will take place in the Tokyo Stadium - with all five disciplines in one venue - during the Summer Olympic Games 2020."
Noriyuki Nakamura, modern pentathlon competition manager for Tokyo 2020, added: "We are working very closely with UIPM to deliver a wonderful Olympic Modern Pentathlon and this test event will give sports fans in Japan and around the world a glimpse of what is in store in 2020."
This year's UIPM World Cup final was staged in the Lithuanian capital of Vilnius, with Almaty, Kazakhstan slated to play host in 2018.
