Japanese organizers admit public awareness of the Asian Games in Aichi-Nagoya "needs to be higher" as they look to ramp up interest with Friday marking a year to go until the start of the sporting spectacular.

The pandemic-delayed 2023 edition in Hangzhou, China, featured about 12,000 athletes — the biggest Asian Games in history and more than the Olympics.

Host Japan hopes next year's event, when athletes will stay on a "floating village" cruise ship and in converted shipping containers, will make a similar splash.
