The Japanese Olympic Committee has set an ambitious target of 30 gold medals for the 2020 Olympics, almost double the national record.
The Asian Games, being held Aug. 18 to Sept. 2 in the Indonesian cities of Jakarta and Palembang, are an important stepping stone.
While Japan can always count on medals in traditional Japanese sports such as judo and karate, the Asian Games will give the country a chance to gauge preparations in sports they haven't always dominated.
At the Asian Games, they'll face a stern challenge from China's 4x100 relay, silver medalists at the 2015 world championships and another Olympic medal contender.
"We're aiming for the gold medal in Indonesia," Yamagata said at a recent training camp.
"We want to use the Asian Games to build confidence toward next year's world championships and the Olympics in 2020."
Cambridge, whose father is Jamaican and mother is Japanese, competes in both the 100- and 200-meter sprints as well and is one of the rising stars in Japanese athletics.
"We can feel the excitement building," Cambridge said.
"There are a lot of runners in the 100 (at the Asian Games) who can run under 10 seconds so I expect it will be a very tough race."
Five new sports have been added to the program for Tokyo 2020, and the Asian Games will feature several of those.
Japan has established itself as a global powerhouse in bouldering, one of three disciplines in sport climbing, and will be aiming to dominate the event in Indonesia.
Baseball and softball are also returning to the Olympic program in Tokyo and, while Japan has always been a medal contender, the Asian Games will provide a good test run after a long absence from international competition.
Another area where Japan is expecting an impressive medal haul is in the pool.
The 18-year-old Ikee competed in seven disciplines, including relays, at the Rio Olympics. She is the junior world record holder in the 50-meter freestyle and 50-meter butterfly long-course events.
