Matsuo Basho was a poet of the early Edo period. He raised haikai poetry to the level of an art and is revered as Japan’s greatest haiku master.
In 1689 he traveled through northern Japan with his disciple Sora and wrote the travel journal The Narrow Road to the Deep North. On this journey he visited the Killing Stone in Nasu, Tochigi Prefecture, and wrote a haiku about it. The stone is said to be the transformed nine-tailed fox.
