Darwin called ginkgo trees living fossils. In fall, they offer a fun splash of yellow to the colorful landscape. Today, we focus on their nuts! The outer shell may smell a bit funny, but inside is nothing but great flavor. Harvest ginkgo nuts from 10,000 trees at a famous production site and chow down with local farmers. Feast your eyes on traditional recipes, and discover how the nut is paired with champagne at a French restaurant in Tokyo. (Reporter: Zack Bullish)

Our saba journey begins at Tokyo's Toyosu Market. We then visit Kyoto Prefecture for some festival food that remains a key part of local tradition before heading to Obama, Fukui Prefecture, at the other end of the Saba Kaido, a historic trade route. Regional synergy continues to this day, with sake lees from Kyoto playing a key role in aquaculture at Wakasa Port. Also discover the expanding world of canned saba, and cook outside with our reporter, Michael, using organic veggies from his farm. (Reporter: Michael Keida)
