Kamose, a private cooking studio run by fermentation specialist Nobuaki Fushiki, is hidden among the backstreets of Tokyo's Gakugei Daigaku district. Fushiki's special dinner events, which feature an array of fermented ingredients, have a clandestine quality that brings to mind the speakeasies of the Prohibition era. Entering through the back of the residential building that houses the studio, guests speak softly to avoid disturbing the neighbors. As at some of the city's small, exclusive restaurants and supper clubs, reservations at Kamose usually require an introduction. Seats for the dinner events fill up quickly, but the website lists no phone number.
