TRAILS TO OISHII TOKYO - SOY SAUCE

Soy sauce is key when it comes to the flavor of Japanese food. This time, we ask a specialist about the differences in color and flavor between sauces. We also see a soy sauce maker which prepares its sauce in wooden barrels used for over 100 years. In order to pass this disappearing method on, the maker started to produce its own barrels. Finally, we learn about a new type of sauce popular in France and virtually unknown in Japan. Join reporter Kyle from Canada as he dives deep into soy sauce. (Reporter: Kyle Card)
