Tokyo's success in landing the 2020 Olympics and Paralympics was thanks to the country's all-around effort involving athletes, lawmakers and business leaders, Gov. Naoki Inose said after returning from the International Olympic Committee's general assembly in Buenos Aires.

"Our bid came to fruition as 'Team Japan' worked with good teamwork," Inose, who is also chairman of the Tokyo 2020 Bid Committee, said Tuesday night while also thanking the public, who "were awake at 5 a.m. cheering for the bid."

"Frankly speaking, the bid wouldn't have succeeded if the Japanese Olympic Committee worked alone," said former Prime Minister Yoshiro Mori, who was vice chairman of the bid council and went to the general assembly.
