For centuries, legends have focused on mermaids but had shed a dime light on the real sea women of Japan.
Ama, or sea women, are pearl divers that have been doing this profession for a living since the 8th-century. Considered more fit than men to do this job, because of their higher fat content and endurance in the near-freezing temperatures of seawater which they dive in, women are trained to become amas at the age of 12. With the mentoring of an old family member, amas develop the necessary skill and exercise the profession until their death.
The demand for amas increased when Kōkichi Mikimoto a Japanese pearl farmer, and businessman developed the commercial production of cultured pearls in 1893.
Dressed in Mikimoto amas would free-dive to depths of 30 feet, holding their breath for few minutes.
Like real mermaids, they would emit an “ocean whistle” once they re-surface in order to help regulate their breathing after a long dive.
Today these sea women are not extinct but rare to find. They became more of a touristic attraction or entertainers, you can catch them perform diving operations in places such as Mikimoto Pearl Island.
