"Karuta (かるた?, from Portuguese carta ["card"])[1] are Japanese playing cards. Playing cards were introduced to Japan by the Portuguese traders during the mid-16th century. These early decks were used for trick-taking games. Karuta packs are divided into two groups, those that are descended from Portuguese cards and those from Eawase.[2] Eawase was originally played with shells but were converted to card format during the early 17th-century."

"The first indigenous Japanese deck was the Tenshō karuta named after the Tenshō period (1573-1592).[3] It was a 48 card deck with the 10s missing like Portuguese decks from that period. It kept the four Latin suits of cups, coins, clubs, and swords along with the three face cards of female knave, knight, and king. In 1633, the Tokugawa shogunate banned these cards, forcing Japanese manufacturers to radically redesign their cards. As a result of Japan's isolationist Sakoku policy, karuta would develop separately from the rest of the world. In order to hide the proscription of Portuguese derived cards, makers turned the cards into very abstract designs known as mekuri karuta." 

"Kabufuda (Japanese: 株札) is another derivative of mekuri karuta but all the suits were made identical. It is used for gambling games such as Oicho-Kabu. They come in decks of 40 cards with designs representing the numbers 1 through 10."

"Like hanafuda, kabufuda is a descendent of mekuri karuta. Since suits don't matter in kabu games, all decks became single-suited during the 18th-century.[1] Like in baccarat, the object of most kabu games is to get a total closest to nine. [2] Early kabufuda decks had three ranks of face cards but since they have no value, only the jacks were kept. Kabu is believed to derive from the Portuguese slang cavo meaning a stake, bet, or wager."
