Kashiwajima is located on the edge of Shikoku Island and considered as “The place for Macro diving” In Japan. We are a small diving service in the center of Kashiwajima.
Our mission is to promote this wonderful diving area to many divers all around the world and make sure that whoever visited us will have the best diving holiday ever.
We(AQUAS) will work hard to help make this happen. We want our guests to finish their weekend with a satisfying comment “Best holiday ever!”

At AQUAS, we respect our ocean.
We want to tell the world of how beautiful Kashiwajima’ s oceans are. And in doing so, we believe that we are paying back what we owe to our ocean.
So let us guide you. We will slowly and gently guide you through the waters as if we are drifting comfortably and with a big smile from everyone in the group to end the tour.
This is our style.
And at night, we could all gather around and look back on the day and with a drink, share the photos and memories with friends and buddies.
