A Douka or dōka is an ethical Japanese Tanka (poetry) with a lesson. Well-versed poems of Douka contain the central dogma, appealing to Japanese people and easy to memorize.
Dōka and its popularity in Japanese culture
 There is a wide range of Dōka and its contents are said to cover not only lessons but also worldly wisdom. The writers of Dōka are recorded to be many, but some of them composed originally Tanka and their Tanka was interpreted by others as Dōka.

History of Dōka
- Anrakuan Sakuden (安楽庵策伝?, 1554 - February 7, 1642) was an Edo period Japanese priest of the Jodo-shu (Pure Land) of Buddhism; and a poet. He wrote a book Seisuisho (醒睡笑, Laughs to Wake You Up), which is a collection of humorous anecdotes. In volume 3 of this book, the word Douka was first used. However, the Japanese have liked composing Tankas with lessons from time immemorial. Later, Ishida Baigan started Shingaku (心学, lit. "heart learning") and used Dōka in his religious movement. Dōka is remembered in everyday life of Japanese.
