These vintage Japanese bromide cards — known as Pachimon Postcards — were published by Yokopro in the 1970s. They feature “pachimon kaiju”, counterfeit monsters that have been painted into scenes of familiar tourist attractions and locations around the world. As imitations of assorted monsters from Japanese TV shows and feature films, pachimon kaiju mimic various Toho creations and offer more than a hint of weird critters from the Ultraman franchise. They also seem to me to reference traditional Japanese yokai — monstrous spirits and demons from folklore. Either way, they’re a wonderful nod to the strange world of Japanese kaiju.
