Hyakunin Isshu is the most famous and popular collection of Japanese poetry, and the first work of Japanese literature ever to be translated into English. Compiled in the fourteenth century, the book is a collection of one hundred waka poems (a precursor of haiku), dating back to the seventh century. It's had a huge influence on Japanese culture ever since it was first published, and is considered one of the three most important works of Japanese classical literature along with The Tale of Genji and Tales of Ise.
