Nakandakari Hijaa: Okinawa's Historic Communal Spring

Tucked into the hillside of a quiet farming village in southern Okinawa, Nakandakari Hijaa (仲村渠樋川) is one of Japan's most remarkable examples of a traditional Ryukyuan stone-built spring. Designated as a nationally Important Cultural Property in 1995, this communal water facility tells the story of how Okinawan villagers once lived in harmony with natural spring water — drawing on it for drinking, bathing, washing, and even spiritual worship. Known locally as "Ufugaa," the spring remains an enduring symbol of the island's deep-rooted water culture.

A Spring Reborn in Stone

The history of Nakandakari Hijaa stretches back centuries. For generations, the people of the Nakandakari settlement relied on this natural spring, which gushes from the Ryukyu limestone bedrock on the hillside. In its earliest form, the spring was little more than a simple wooden trough set beneath the water source.

That changed between 1912 and 1913, when skilled stonemasons from Tsuken Island were brought in to reconstruct the facility using blocks of Ryukyu limestone. The result was a beautifully engineered complex of water channels, bathing areas, a stone-paved path, a communal plaza, and even a sacred prayer site — all carved from the island's native coral rock. Although the spring suffered damage during the Battle of Okinawa, it was repaired in 1964 and then meticulously restored to its 1912 appearance during a major project completed in 2004.

Why It Was Designated an Important Cultural Property

The Japanese government designated Nakandakari Hijaa as a nationally Important Cultural Property on June 27, 1995. The spring earned this distinction for several reasons:

• It is considered the finest surviving example of a traditional Okinawan stone-built communal spring (石造井泉), showcasing the distinctive water-management techniques of the Ryukyu Islands.
• Its complex layout — incorporating separate bathing areas for men and women, a communal gathering space, a prayer site, and a stone-paved access path — provides invaluable evidence of how rural Okinawan communities organized their daily lives around shared water resources.
• The facility uniquely features a Goemon-style iron-kettle bath (五右衛門風呂), the only known example at a communal spring in Okinawa, demonstrating the cultural exchange between mainland Japanese and Ryukyuan bathing traditions.
• The skilled Ryukyu limestone masonry, executed by Tsuken Island craftsmen in the Taisho era, represents an important chapter in Okinawa's architectural heritage.

Exploring the Spring: What to See

Visitors approaching from the village above will first encounter the kaabira (かーびら), an atmospheric stone-paved slope that descends from the settlement to the spring. Walking down this path feels like stepping back into a bygone era of Okinawan rural life.

The Water Culture of Southern Okinawa

Nakandakari Hijaa is part of a broader "water culture" that defines southern Okinawa's Tamagusuku district. The porous Ryukyu limestone bedrock of this region acts as a natural filter and reservoir, producing numerous springs that have sustained communities for centuries. Until a modern water supply system was installed in 1955, the spring was the settlement's sole source of water for all domestic purposes.

The area around Nakandakari is also home to other important water-related heritage sites. Nearby Kakinohana Hijaa (垣花樋川), selected as one of Japan's Top 100 Spring Waters, and the legendary Ukinjuhainiju (受水走水), considered the birthplace of Okinawan rice cultivation, together paint a rich picture of how water shaped life, agriculture, and spirituality across this landscape.
