Kabufuda	Kyoto, Osaka, Kobe, Tanba, Tango, Tajima, Banshu, Bizen, Kishu, Iga, Yamato, Kwachi, Izumi, Settsu	40	Consists of 4 copies of the numbers 1 to 10, with a special overprinted 1 and 4. The only court card “10” looks like a two-way Jack holding a very short sword, but its body is based on the Queen of Clubs of a western playing card deck (Some manufacturers used the King of Diamonds as a reference instead). Also called Nukinokichi because it is technically a reduced Irinokichi deck.
Irinokichi	Kishu, Shima, Ise (Japan) East & West Haozhou (China)	48	The original 48-card deck where Kabufuda came from. There are 3 court cards (10, 11, 12), whose designs look more like the 2 of coins, the horse of clubs, and the king of clubs in a mekurifuda deck. Comes with Onifuda. It is believed that the name comes from some manufacturers printing the character 吉 (kichi) in silver on one of the cards. Kingo-style games were often played using this pattern.
Kinseizan	Tsuruga, Kii, Ise, Shima	48	A deluxe version of Irinokichi where many of the cards are overprinted with silver and gold. All 1, 2, 10, 11, and 12 cards are overprinted. Special 4 is overprinted like Kabufuda, while Special 1 has a Paulownia and Cloud overprint. Comes with Onifuda. Variants of Hiki-Kabu, as well as Kingo-style games were played using this pattern.
Hosonokichi	Wakayama, Mie, Fukui	48	A budget version of Irinokichi where the Clubs and Swords are made up of thin lines. Originally, instead of using stencils to color the cards, they were hand-painted using a thin brush, as a way to reduce material cost and production time.
Dai-ichiroku	Karafuto (now Sakhalin, Russia)	48	The cards are bigger than Mame-ichiroku. 8 copies of the numbers 1 to 6. Used in the betting game Karafuto Kabu.
