Kakihanahi-jaa (垣花樋川), located in the Tamagusku district of Nanjo City, Okinawa Prefecture, is a representative spring water spot in Okinawa that was selected as one of Japan’s Top 100 Famous Waters by the Ministry of the Environment (formerly the Environmental Agency) in 1985. The clear water that gushes forth from layers of limestone has long been used as domestic water by local residents, and is still cherished by many people today as agricultural water and a place of relaxation.
This article provides comprehensive information you should know before visiting, from the historical background of Kakihanahi-jaa, its unique culture, access methods, and information about nearby tourist attractions.
What is Kakihanahi-jaa? History and Culture of Okinawa’s Famous Water
The Meaning and Origin of “Hi-jaa” (樋川)
In Okinawan dialect, “hi-jaa” (樋川) refers to a spring well where spring water is diverted through a kakehii (掛樋). Although there are numerous hi-jaa throughout southern Okinawa Main Island, Kakihanahi-jaa is particularly known for its abundant water volume and excellent water quality.
The place name Kakihana is derived from the Kakihana Castle that once stood here. Clear water continues to gush forth from the middle of a forest below the stone-paved slope of Kakihana Castle ruins, unchanged from the past.
Significance of Selection as One of Japan’s Top 100 Famous Waters
The Top 100 Famous Waters selected by the Environmental Agency in 1985 designates 100 locations throughout Japan with excellent water environments, and Kakihanahi-jaa is a rare selection as the only one chosen in Okinawa Prefecture. This designation was based on comprehensive evaluation not only of water quality but also of historical and cultural value in the region and landscape beauty.
At the time of initial selection, it was recognized as one of 31 locations, and through subsequent additions, it eventually became one of 100 locations. This can be said to be a result of evaluation of the abundance of Okinawa’s water resources and the long-term conservation activities of local residents.
Inagunkaa and Ikigankaa｜Traditional Gender-Separated Usage
The greatest characteristic of Kakihanahi-jaa is the existence of two springs side by side. The left side is called “Inagunkaa” (Women’s Stream), and the right side is called “Ikigankaa” (Men’s Stream), and they were traditionally used separately by men and women.
The Role of Inagunkaa (Women’s Stream)
Inagunkaa was a place where women used water for household chores such as laundry and vegetable washing. From the Ryukyu Kingdom era until the early Showa period, women gathered here and, while performing communal tasks, used it as a place for information exchange and social interaction. The water source was not merely a place to obtain domestic water but also served as an important social gathering place for the community.
The Role of Ikigankaa (Men’s Stream)
Ikigankaa was primarily used by men to wash their bodies after agricultural work or to clean farm tools. It was also utilized as agricultural water, supplying water to paddies and fields in the surrounding area. This gender-separated usage is a valuable heritage that conveys Okinawa’s traditional lifestyle culture to the present day and serves as one of the important highlights when visiting Kakihanahi-jaa.

A Healing Space Surrounded by Lush Greenery
