The barista began working in a Tokyo café when he was 20, and initially experimented with making leaves out of steamed milk, he told Business Insider in an email.
One day, a friend challenged him to try drawing an anime character in the foam. After his initial success, Yamamoto realised his talent and expanded to elaborate designs that he began to post to his Twitter account.
Yamamoto now has more than 100,000 followers, and the young barista updates his account frequently with illustrations of cartoon characters, actors, musicians, and landscapes.
And in case you thought the coffee would be cold by the time it gets to the customers, Yamamoto assures us that each creation takes him at most four minutes to complete, and that the drinks are still hot when served to patrons.
This cute design has a cat reaching over to another coffee cup to watch fish swimming in the coffee.
Of course, Pokémon characters also make an appearance in Yamamoto's work. He does an impeccable job with Vileplume here.
Despite his elaborate designs, Yamamoto insists to Business Insider the coffee is never sold cold to his customers.
