The 10 sets of siblings representing Japan at the Beijing Olympics will use their family links to bring out the best in each other, with some tapping into long-standing rivalries while others work together for a common goal.
There were 11 sets of Japanese siblings at the Tokyo Games, but also a much larger team of 583 total athletes. This time the percentage is higher, with one-sixth of the team made up of siblings.
Of the 124 athletes on Japan's Winter Games team, 20 are competing with or against their brother or sister and all are facing the unique challenge of having both national and family pride on the line.
