Kit Kat is big in Japan. From cheesecake to wasabi to purple sweet potato, the crunchy waffle bar is available in more than 400 varieties, according to Yuji Takeuchi, marketing manager for Nestlé Japan. And it is up to Yasumasa Takagi to keep the fresh flavors. So far, the classically trained pastry chef has added over 50 to the Kit Kat canon. Takagi invites us to his kitchen in Tokyo to see how he creates delicious new taste profiles for customers who are always hungry for more.
