Kobayashi Issa (小林 一茶?, June 15, 1763 - November 19, 1827), was a Japanese poet and lay Buddhist priest of the Jōdo Shinshū sect known for his haiku poems and journals. He is better known as simply Issa (一茶?), a pen name meaning Cup-of-tea (lit. "one tea"). He is regarded as one of the four haiku masters in Japan, along with Bashō, Buson and Shiki - 'the Great Four, Basho, Buson, Issa, Shiki'.
Reflecting the popularity and interest in Issa as man and poet, Japanese books on Issa outnumber those on Buson, and almost equal in number those on Bashō.
