Hidetoshi Nakata is one of Japan's most recognizable stars. A veteran of three World Cups, he retired from football in 2006, when he was just 29. Now, more than decade after his final professional match, Nakata is once again representing Japan, this time as an ambassador for the country's traditions and master craftsmanship. Nakata takes CNN's Will Ripley on a journey to explore the refined world of sake, a Japanese alcohol made from rice. In snowy Yamagata Prefecture, we visit the famed Takagi Brewery, an institution with a history dating back to 1615. In Tokyo, we meet some of Japan's most renowned chefs, who tell us why sake embodies the true Japanese flavor to be shared with the world.
