Whisper from TOTORO

Speaking about harvest moon, I remember a card of "hanafuda" (花札) Hana means flower and fuda means cards.

The upper left card shows the harvest moon and susuki (pampas grass).
The kanji in the left lower card shows "nintendo" (任天堂)
Nintendo was originally a hanafuda maker.

Hanafuda is a kind of playing cards. About 500 years ago, Portuguese brought European playing card to Japan.
Soon, it bacame popular and often used for gambling.
To avoid revelation from governers, they changed the style and design like this for camouflage.
12 kinds of flowers or plants are set in each month instead of Spades,Clubs, Diamonds and Hearts.The theme of these pictures comes from ancient short poems.
