Oku no Hosomichi (奥の細道?, originally おくのほそ道, meaning "Narrow road to/of the interior"), translated alternately as The Narrow Road to the Deep North and The Narrow Road to the Interior, is a major work of haibun by the Japanese poet Matsuo Bashō, considered "one of the major texts of classical Japanese literature."
The text is written in the form of a prose and verse travel diary and was penned as Bashō made an epic and dangerous journey on foot through the Edo Japan of the late 17th century. While the poetic work became seminal of its own account, the poet's travels in the text have since inspired many people to follow in his footsteps and trace his journey for themselves. In one of its most memorable passages, Bashō suggests that "every day is a journey, and the journey itself home." The text was also influenced by the works of Du Fu, who was highly revered by Bashō.
Of Oku no Hosomichi, Kenji Miyazawa once suggested, "It was as if the very soul of Japan had itself written it."
Bashō's introductory sentences are the most quoted of Oku no Hosomichi:
Oku no Hosomichi was written based on a journey taken by Bashō in the late spring of 1689. He and his traveling companion Kawai Sora () departed from Edo (modern-day Tokyo) for the northerly interior region known as Oku, propelled mostly by a desire to see the places about which the old poets wrote in an effort to "renew his own art." Specifically, he was emulating Saigyō, whom Bashō praised as the greatest waka poet; Bashō made a point of visiting all the sites mentioned in Saigyō's verse. Travel in those days was very dangerous, but Bashō was committed to a kind of poetic ideal of wandering. He traveled for about 156 days altogether, covering almost 1,500 miles (2,400 km), mostly on foot. Of all of Bashō's works, this is the best known.
