Frozen yogurt is taking off in Tokyo as a healthy alternative to ice cream in an effort to beat the heat. Made from milk instead of cream, frozen yogurt packs far less fat and more nutrients. Woodberry's uses freshly homemade fermented yogurt and fruits straigh from the farm. A limited-edition passion fruit flavor — shipped from Fukuoka — is available until May 7. There are other flavors to choose from made with local or organic produce such as avocado, yuzu and Ehime Prefecture lemons.
