Otawara, Kurohane Castle and the Land of Basho — Where the Poet Stayed Longest

Kurohane in Otawara City, Tochigi Prefecture, is known as the place where Matsuo Basho stayed longest, a full fourteen days, during his journey recorded in Oku no Hosomichi. In 1689, warmly received by the castle chief retainer of the Kurohane domain, Johoji Tosetsu, and his younger brother Kanokobata Suito, Basho grew deeply attached to the rich nature and the kindness of the people here and composed many fine haiku. Overlooking the broad Nasuno plain, the area remains a place tied to literature that lovers of haiku still visit from across the country.

Highlights

Kurohane Castle was built in 1576, the fourth year of Tensho, when Ozeki Takamasu moved his base from Shirahata Castle. Because the Ozeki clan sided with the eastern army at the Battle of Sekigahara, they kept their domain and continued as lords of Kurohane until the Meiji Restoration. Today it is maintained as Kurohane Castle Ruins Park, where earthen ramparts and deep dry moats built on the hill overlooking the Naka River preserve the sturdy layout of old in good condition. The green grounds are a place of rest for local people, and from the raised main enclosure you can survey a grand panorama of the Nasu mountains and the Nasuno plain. In one corner of the park, the Otawara City Kurohane Basho Museum displays materials related to Oku no Hosomichi and items connected to the Kurohane domain. Haiku monuments are scattered throughout the city, and following them on a stroll is popular.

Enjoying the Seasons

Early April for cherry blossoms, early summer for hydrangeas, and November when the leaves turn are the most rewarding times. Around the castle ruins, many hydrangeas bloom from late June into early July, and the Kurohane Hydrangea Festival welcomes many visitors. The sight of the ruins tinted purple and blue has a charm particular to this season.

Access and Basic Information

Access is by bus, taxi, or car from Nishinasuno Station on the JR Tohoku Main Line or Nasushiobara Station on the Tohoku Shinkansen. Because the site sits on a hill somewhat away from central Kurohane, visiting by car is convenient. The Nasu hot spring area and Nasu Highlands resorts are also close by car, making for an easy touring base.

Practical Travel Notes

• The castle park has uneven terrain, so comfortable shoes are recommended, and touring the ramparts and dry moats gives a clear sense of the old castle layout.
• Since the haiku monuments are scattered across the city, picking up a monument map at a tourist information center helps you tour efficiently.
• Visitor numbers rise during the hydrangea festival, so allow extra time.
• A two-day trip combining a literary walk in Basho's footsteps with the grand nature and fine hot springs of Nasu is recommended.

A Word of Advice

Kurohane is a town best walked slowly, sensing why Basho grew so attached to it over fourteen days, rather than rushing through sights. Stand on the raised castle ground and the sweep of the Nasuno plain opens before you. Follow the haiku monuments and enjoy a quiet literary walk.
