The Wikipedia has the following information about this codepoint:
Hanafuda (Japanese: 花札, lit. 'flower cards') are a type of Japanese playing cards. They are typically smaller than Western playing cards, only 5.4 by 3.2 centimetres (2.1 by 1.3 in), but thicker and stiffer, and often with a pronounced curve. On the face of each card is a depiction of plants, tanzaku (短冊), animals, birds, or man-made objects. One single card depicts a human. The back side is usually plain, without a pattern or design of any kind, and traditionally colored either red or black. Hanafuda are used to play a variety of games including Koi-Koi and Hachi-Hachi.
