Basho - The old pond, a frog jumps in, the sound of water

This is perhaps Matsuo Basho's most well known poem. For a great look at how differently this poem is translated see Matsuo Basho Frog Haiku (Thirty-one translations and one commentary). The translation we use here is by R. H. Blyth.

Note that we have used the shorted version of tobikomu, the full form is 飛び込む (read tobikomu) meaning "to jump in; to leap in; to plunge into; to dive in".
