Hwatu cards are the Korean version of Japanese Flower Cards with red backs. The cards came over to Korea when the Japanese occupied it during 1905-1945. The locals took to this game swiftly and before long an idiosyncratic local version appeared. The differences between the Japanese and the Korean decks are slight, mainly in the colouring of the cards which is very vibrant.
The cards are printed on thick, red plastic, instead of the laminated board (with turnover edges), used in Japan. On some of the cards you will notice the word "光" meaning bright, used to identify certain high scoring cards, a feature absent in the Japanese one. The moon card of the month of July (top row, 3rd from left) has the maker's name in the moon. The deep purply blue used in the Japanese cards has been replaced with a light blue in the Korean ones. The deck has an extra 6 cards, used as bonus cards. more info →
