About us
SEASIR was established in 1983 as a small diving shop on Aka Island.
Since then, it has grown into the largest diving company in Okinawa.
Today, we operate four diving and marine activity shops, a diving equipment store, an overhaul center, a hostel, a guesthouse, and a travel agency in Okinawa.
In 2019, we also opened a diving shop in Cebu, the Philippines.
Our company vision is to serve as a gateway for everyone to experience the wonders of nature,
and to inspire a shared commitment to protecting the ocean—our most exceptional natural heritage.
