What is hanafuda?
Hanafuda ("flower cards") is a Japanese deck of 48 cards, twelve months with four cards each, each month shown by a flower or tree: pine, plum, cherry, wisteria, iris, peony, bush clover, pampas, chrysanthemum, maple, willow and paulownia. Koi-Koi is the most popular game played with the deck, and it is easy to learn: you only need to match months. The depth comes from the yaku, the scoring combinations such as the Five Brights, Boar-Deer-Butterfly, or the red and blue poetry ribbons, and from the choice between taking your points and pushing your luck.
Five venues, one calm game
Play at the Koto Garden, a lively Festival, a quiet Night Table, a Temple, or under the Moon. Each venue has its own table colour and original music, and the game can change venue every round or stay on your favourite.
