One of the country's medal hopefuls is 23-year-old Kiyo Shimizu. She's the queen of Karate's kata -- a floor routine that focuses on form and execution. The Japanese sport is a new addition to the Olympics.
Another newly added sport is climbing, and even though 16-year-old Ashima Shiraishi is based in the US, she's competing for Japan. Shiraishi has yet to lose at the World Youth Championships.
In track and field, all eyes in Japan are on 18-year-old Abdul Hakim Sani Brown. He's also getting some global attention, having won the rising star award from the international athletics federation. He's expected to run 100-meters below the 10-second barrier -- a mark that's required of world-class sprinters.
In table tennis, 14-year-old rising star Tomokazu Harimoto stunned sports fans when he beat the Olympic bronze medalist at the World Championships.
In the pool, Ippei Watanabe is a new hope for medaling in the breast stroke. In January, he broke the world record.
And finally, in badminton, 20-year-old Akane Yamaguchi, ranked No.2 in the world, is hoping to make it to the podium come Tokyo.
Athletes competing in the Tokyo Olympics will stay at the Olympic Village, which will be equipped with unique facilities and services designed to help the athletes perform at their peak.
The athletes will be able to see the Tokyo Bay from their bedrooms while at the games.
Harumi is an artificial island and one of Tokyo’s leading commercial development zones.
The Olympic Village will be surrounded by water on 3 sides, and will stand at a roughly central point among the athletic facilities in the Tokyo metropolitan area.
The village is in a pretty good location in terms of being able to take in what the city has to offer. Ginza, one of the city's most famous commercial districts, is easily accessible.
Construction is scheduled to finish in 2.5 years.
The Tokyo metropolitan government is planning to make the area ecologically friendly by installing hydrogen refueling stations and using buses and automobiles that do not emit carbon dioxide.
Organizers say the village will feature 21 high-rise blocks, which will house nearly 20,000 people from about 200 countries and territories.
A temporary jogging course will be built, as well as a main dining hall where an estimated 15-million meals will be served.
Farmers are hoping their products will be used. For that to happen, they need to clear a big hurdle -- an international standard that's new to them.
