About Us
SEASIR started as a diving shop on Aka island in 1983.
We expanded over the years and also cater to non-divers with the best of fun to be had in Okinawa:

We also launched other businesses such as an equipment shop, a travel agency and accommodations to cater to all of your needs during your stay in Okinawa.
Multilingual instructors and receptionists are present in each branch to make sure that you will feel welcome and catered to wherever you go with SEASIR.
