Pachimon (パチモン is a series of vintage bromide trading cards made by the Pachimon)Japanese companies Yokopro (ヨコプロ and Yamapro Yokopuro) (ヤマプロ).
Pachimon was created by Yokopro in the 1970's, around the time kaiju were very popular in Japan. The card game consists of several "Pachimon," monsters often based on those from popular kaiju series such as Godzilla, Gamera and the Ultra Series, usually shown attacking famous cities or places.
The playing cards feature information on each monster, including its height, weight, and subtitle.
Although quite obscure, the Pachimon kaiju have garnered something of a cult following among Japanese collectors and otaku, which has resulted in vinyl figures (both official products and custom built independents), fan-made video games, and short films.
"Monster Collage" and "Dinosaur" Editions
The first series published by Yokopro featuring lone monsters appearing among the city, often Japanese locations. A secondary "Dinosaur" version was also issued alongside the "Monster Collage" cards.

Monster World Tour
Perhaps the most recognizable of the Yokopro releases, this second series features giant monsters menacing famous cities, landmarks, and natural wonders outside of Japan. All these monsters were originally nameless but were given such titles in later playing card editions.
Third series featuring both named and unnamed characters, the latter coming from a Monster Confrontation set.
Fourth series supposedly sold only at Japanese candy stores.
Bromide cards produced towards the end of the decade under various miscellaneous series like New Monsters and Iwata Pro Large Monster Edition. Although Pachimon is infamous for culling from other monster characters and related image sources, the dip in quality is most apparent with these later entries.
Playing cards that reuses older images and characters alongside some new additions, mainly taken from Japanese picture books related to dinosaurs, fantasy monsters, and science fiction.
Kewpie Corporation Playing Cards
The following set of promotional playing cards were produced by the Kewpie Corporation and featured original creature artwork along with related names and stats. However, these cards are still often lumped together with other Pachimon due to some of the designs still being derivative of existing characters.
Merchandise / Miscellaneous
Merchandise, toys, and fan-created projects inspired by Yokopro's Pachimon bromide cards.
- Several of the kaiju depicted on the Pachimon cards are modified pictures of kaiju from the Godzilla, Gamera, and Ultra franchises.
- Some of the Ultra Series-inspired inspired kaiju are Africa, based on Sadola, Himular has Red King's body, Kokura and Lygon are based on Bemular, Purachi is Windom, Tonga is Star Bem Gyeron, an unnamed monster with Peguila's body and Gomora's head, and another unnamed monster with Red King's body and Gamera's head.
- Some Pachimon cards took their visual sources from outside the kaiju and tokusatsu genres, including science books based on prehistoric animals and photographs of modern day ones. Jiatorima, Skorosaurus, Triceratops, a gigantic Dunkleosteus, and an unnamed mountain hugging Komodo dragon are some such examples.
- There is a minority of Pachimon card creatures who appear to be fully original creations and connected designs. But these too could have also been taken from more obscure sources, like artwork from kaiju picture books and science fiction magazines.
- The ghastly character with the claws of the iconic Ultraman villain Alien Baltan, the body of Antler (also from Ultraman), and an over-sized human skull for a head, was originally left nameless in its card debut, but would later be named "Galtan" (or "Gaikotsubaltan") by the vinyl sculptor Exohead, who released a figure of the monster in 2007.
- An unofficial Pachimon fighting game similar to MUGEN titled Pachimon Kaiju Dainessen exists.
- Through this unofficial video game, one unnamed Dunkleosteus-based monster was given the fan-created name of "Whow."
