Sporting figures at home and abroad paid tribute to Shinzo Abe over the former prime minister's large role in Tokyo's securing the 2020 Olympics and Paralympics.
His close connection with the former Tokyo Games organizing committee president Yoshiro Mori, also a former prime minister, proved crucial during the preparations for the games that were postponed for a year following the outbreak of the COVID-19 pandemic.
Japan won its hosting bid at the Sept. 2013 International Olympic Committee Session, just two years after the March 2011 earthquake and tsunami that devastated northeastern Japan's Pacific coast and triggered multiple meltdowns at a nuclear power plant.
Abe did his best to calm concerns about contaminated water leaking from the facility by declaring "the situation is under control."
"He really led us from the front. He really gave us the power with that speech in Buenos Aires," former Japanese Olympic Committee President Tsunekazu Takeda said. "I'm really disappointed (about his death)."
In 2015, Olympics costs and the organizers' opaque bidding procedures became a point of criticism when the public learned the original design for a new National Stadium, by the late architect Zaha Hadid, would cost far more than originally announced.
Abe bit the bullet, canceled the order and reopened bidding for the new stadium.
He then helped set an optimistic mood for the 2020 games by appearing in the 2016 Rio de Janeiro Olympics' closing ceremony clad in the costume of the world-famous video game character "Mario."
On March 24, 2020, soon after the United States Olympic & Paralympic Committee and its influential athletics and swimming federations urged a postponement, Abe agreed with IOC President Thomas Bach and announced the unprecedented delay.
"(Hosting the games) could have been difficult had there been no postponement. We could only move if the prime minister made the decisions. It was a hugely good decision," Toshiro Muto, the CEO of the organizing committee, said.
He stepped down from his prime ministerial post in September that year, but was awarded the Olympic Order by Bach in November for his contribution to the Olympic movement.
"I am deeply shocked by this cowardly attack on former Japanese Prime Minister Abe Shinzo," tweeted Bach.

International Paralympic Committee President Andrew Parsons thanked Abe, writing his organization "will forever be grateful to the people of Japan for delivering the Tokyo 2020 Paralympic Games in the most demanding of circumstances."
World Rugby Chairman Bill Beaumont said Abe's murder was "Incredibly tragic news" after Japan hosted the 2019 Rugby World Cup.
"He was a huge supporter of an historic Rugby World Cup in Japan. My heart goes out to his family, friends and the Japanese people at this sad time."
