Yoshiharu Omine
Yoshiharu Omine

Onna Sensui (from Japanese 恩納潜水, meaning Onna Diving) was originally established by Yoshiharu Omine in 1963 as a fishing shop. Then, four years later, Omine-san became certified as a PADI instructor in the resort of Shirahama in Wakayama prefecture and converted Onna Sensui into a diving shop. At that time Okinawa was still a US territory and there was only one diving shop on base where the US military personnel could get trained in scuba diving. In addition, there were only four PADI instructors on the entire island, which was highly insufficient to meet the growing demand. Onna Sensui was thus a huge novelty as the first off-base diving shop and, thanks to the fact that Omine-san could speak English, it originally attracted predominantly American customers who were seeking to get certified as divers. Over the years Onna Sensui acquired a compressor for air fills and gradually shifted its focus towards working with Japanese tourists.

Onna Sensui brochure from 1982

Around the turn of the century Tomoko-san, daughter of the original owner Omine-san, married Yoshitaka Zukeyama, who became the new owner of Onna Sensui Diving Shop. He expanded the shop activities by adding facilities for hydraulic scuba tank inspection as well as metalicon refurbishment of aging steel scuba tanks. He also started manufacturing custom wetsuits and became very skillful at it.

In recent years, Okinawa has become an attractive tourist destination not only for Japanese nationals, but also for foreigners, which necessitates providing modern services in English. However, we would still like to keep the traditional feel of the shop so that when you become our guests, you get immersed not only in the beautiful Okinawan sea, but also into the welcoming Okinawan culture!
