Tokyo will host the 2019 edition of the International Modern Pentathlon Union (UIPM) World Cup Final, it has been announced.
The season-ending event will also double as a test for the 2020 Olympic Games in the Japanese capital.
It will take place in June 2019, 13 months before the Olympic competition.
Tokyo Stadium will host all five disciplines - swimming, fencing, riding, shooting and running - across a single day.
"This is a reality UIPM achieved together with the Tokyo 2020 Olympic Games Organising Committee in 2013," UIPM President Dr Klaus Schormann said.
"Now our modern pentathlon community can look forward to a great opportunity to visit Tokyo in 2019 for the UIPM World Cup Final.
"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.
"We look forward to working with the Modern Pentathlon Association of Japan and the Tokyo 2020 Organising Committee as this vision takes shape."
Noriyuki Nakamura, the modern pentathlon competition manager for Tokyo 2020, welcomed today's news, which was rubber-stamped by the UIPM Executive Board.
"The modern pentathlon test event in Tokyo in 2019 will be an important part of preparations for the Olympic Games and we are pleased that the event will double as the World Cup Final, which is such an important fixture in the sporting calendar," he said.
"We are working very closely with UIPM to deliver 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."
