"The New York Times" described how Fukuda's posters "distilled complex concepts into compelling images of logo-simplicity". His commercial work included his creation of the official poster for the 1970 World's Fair in Osaka. A 1980 poster created for Amnesty International features a clenched fist interwoven with barbed wire, with the letter "S" in the word "Amnesty" at the top of the poster formed from a linked shackle. "Victory 1945", one of his best-known works, features a projectile heading straight at the opening of the barrel of a cannon. A pair of posters created to celebrate Earth Day include a design showing the Earth as a seed opening against a solid sea-blue background and "1982 Happy Earth Day", which shows an axe with its head against the ground and a small branch sprouting upwards from its handle.
