Japan, hosts of the 2017 Asian Winter Games, 2019 Rugby World Cup and 2020 Summer Olympics, also staged the AsianGames in Tokyo in 1958 and Hiroshima in 1994.
"The road map of our main event is very stable," OCA president Sheikh Ahmad Al Fahad Al Sabah said after the decision of the general assembly in Danang, Vietnam.
"Together with our three Asian Games in 2018, 2022 and 2026, the Tokyo 2020 Olympic Games and the next two Winter Olympics in Korea and China..., the sports calendar of Asia will be very busy with continental and international events."
Organisers said in a presentation to the OCA assembly on Sunday that the Games would cost $842 million.
The bid only received the green light from the Japanese Olympic Committee (JOC) earlier this month after the provision of detailed cost estimates.
In those estimates, some 30 percent of those costs are expected to be covered by sponsorship and other revenue, while Aichi prefecture and Nagoya will split the remaining costs on a 70:30 basis.
