Higashiazabu Amamoto might be one of the hardest restaurants to book in Tokyo (it's often booked out up to four months in advance) but the effort it takes to score a seat is more than worth it. At the helm is chef Masamichi Amamoto, a revered sushi master who spent nine years learning the craft at Tokyo's legendary Umi restaurant. Now with a place of his own, this intimate eight-seater sees guests captivated by Amamoto's acclaimed sushi creations.
