What it kind of started was a ski-jumping family. Kobayashi’s older brother and sister, Junshirō and Yūka, and his younger brother, Tatsunao, all became ski jumpers. “I did a lot of other sports, but they organized camps for ski jumping,” says Kobayashi, “so I knew it would get me out of school. But also, it would get me out of my hometown.”
It was at one of these camps, in 2014, that he encountered Japanese ski-jumping legend Noriaki Kasai, the only athlete to ever participate in eight Winter Olympics. That year, Kasai became both the oldest-ever ski-jumping Olympic medalist and winner of a World Cup event. He was forty-two. A year later, he asked Kobayashi to join his Tsuchiya Home Ski Team.
