a stormy sea stretches out to Sado Island / the Milky Way
荒海や佐渡によこたふ天河
araumi ya / Sado ni yokotau / amanogawa[July 1689]

Basho writes
Station 33 – Echigo 越後路
After lingering in Sakata for several days, I traveled [south] a stretch of a hundred and thirty miles to the capital of the province of Kaga. As I looked up at the clouds gathering around the mountains alongside the Hokuriku road, the thought of the distance before me almost overwhelmed my heart. Driving myself all the while, however, I entered the province of Echigo through the barrier-gate of Nezu, and arrived at the barrier-gate of Ichiburi in the province of Ecchu. Nine days I needed for this trip, during which I could not write much, what with the heat and moisture, and my old complaint that pestered me immeasurably.
Already, the night looks different
For tomorrow, on July the sixth,
Once a year
The weaver meets her lover.
The immense Heavenly River*
Spanning a single arch
On the white-capped sea,
Falling beyond on Sado island.
*Milky Way
Explanation, if you please
It is now July, several months into Matuso Basho’s account of his famous Journey to the North. Basho is traveling south in the region of Esshū (越州), along Japan’s western coast and the Sea of Japan. The mountains are an obstacle, the heat and the summer rains have made the journey difficult, causing his “old complaints” of rheumatism and arthritis to scream with discomfort.
Basho arrives to a view of the distant island of Sado. It is night and the stars of the Heavenly River (Milky Way) shimmer on the rough sea.
Tomorrow is the Japanese festival of Tanabata (meaning “Evening of the seventh”; the Star Festival) would begin. The festival celebrates the meeting of the deities Orihime and Hikoboshi (the Japanese names for the stars Vega and Altair respectively). According to legend, the Milky Way separates these two lovers, and they are allowed to meet only once a year on the seventh day of the seventh lunar month of the lunisolar calendar.
