In the spring of 1689 the poet Matsuo Basho sold the house he lived in outside Edo and set out walking, north into the less traveled provinces of Honshu and then down the western coast, a journey of something like fifteen hundred miles on foot. He was forty five, already an established poet, and by his own account and every serious study since, a committed student of Zen Buddhism, trained under a priest named Butcho.
The walking itself was not incidental to the practice. Zen teaching holds that a fixed sense of self is an illusion worth letting go of, and that ordinary experience, looked at closely enough, carries as much spiritual weight as any formal teaching. A journey with no fixed home to return to put Basho directly inside that teaching rather than merely writing about it from a comfortable distance.
He kept notes as he went, and turned them, over the following five years, into Oku no Hosomichi, alternating prose passages with haiku the way a diary might alternate description with sudden feeling. The book was not published in his lifetime; it appeared eight years after his death, in 1702, and it has been read ever since as much for its account of impermanence as for the individual poems inside it.
The genre he was working in, haibun, has no exact equivalent in Western literary categories, which is why any single label applied to Oku no Hosomichi today, memoir, travel writing, poetry collection, only ever half fits. What every reading agrees on is that Basho meant the journey and the writing to be the same act of practice, not one followed by a report on the other.
