The Doko Demo Issyo series has often had merchandise made of it. Most of these include Plush, Themes for PlayStation3 and 4, Calendars by BeXide, figures by Revoltech, and dolls by other companies.
Revoltech[]
In 2007, Revoltech made figures of Toro Inoue and Kuro. These figures included alternate face plates that could be swapped out to give the toy a different expression. This was a release unusual for them as they were known for making mech action figures. When these figures became unexpectedly popular, Revoltech made more Doko Demo Issyo figures. In 2008 they made figures of Suzuki, Pierre, Ricky, and Jun, as well as a rerelease of Toro and Kuro with different alternate face plates.
There are also special figures of Toro and Kuro which were only obtainable by winning them from a UFO Catcher. These figures were in a larger scale than the previous figures, and always included a unique costume for Toro and Kuro.
Calendars[]
