Historical Family Farm Producing Crisp and Fresh Watercress from Natural Island Spring Water

Founded by family farmers Makiyo and Moriichi Sumida in 1928, Sumida Farm began on five-acres of land that it is home to Kalauao Spring. Now run by fourth-generation owner and farmer Emi Suzuki and her husband, the farm has seen many different changes since its birth.

Sumida Farm is the largest watercress farm in the state, producing 70% of the recorded crop. “Eat plenty watercress” is Sumida Farm’s slogan. One cup of watercress contains over 100% of the recommended daily dose of vitamin K, “a fat-soluble vitamin necessary for blood clotting and healthy bones” writes Healthline nutritional magazine. Watercress is also packed with heart healthy benefits and is extremely low in calories making it a delicious leafy green to add to any meal.

In 1928, Hawai‘i required that all watercress sold had to be grown in pure spring water, uncontaminated by any outside waste runoff coming from the mountain streams. Despite the urbanization of the surrounding area and changes in the climate, a recent multi-disciplinary study done by the University of Hawai‘i at Manoa reaffirmed that the Kalauao Spring is still safe and clean enough to drink from. In addition to this confirmation, the study highlighted the positive cultural and environmental impacts that the spring and farm have on the community as a colorful haven amongst the concrete landscape.

 “Our business is centered around the idea of nourishment, not just watercress… farming is always going to be the core of who we are, and we believe that it should be focused also on education and the environment,” Emi explained.
