After obtaining a license, we have created an environment where you can improve even after obtaining a C card while participating in low-priced one-day easy diving lessons held every week. Take part in such a large group tour and find lifelong companions. It is a serious diving school and shop that thinks about divers and is ideal for those who aim for independent diving. We have many visitors from all over the country. Why not enjoy this sport as a lifelong hobby?
Diving allows you to enjoy the deep underwater world that you cannot experience in everyday life. The seas of Kanagawa and Izu are easily accessible from the Tokyo metropolitan area, where you can meet many creatures and once you taste the scenery from the bottom of the sea, you will be addicted. Even after returning to normal life, there are many repeaters who come to dive every month saying, “I want to dive in the sea again“ and “I want to see that fantastic scenery again.“ We hold various courses, but the first one to acquire is Open Water Diver. After that, the more you rank up, the more you will be able to enjoy diving such as sunken ships and underwater caves, and you will be able to meet more kinds of sea creatures.
SSI’s Professional Course offers two options. Those who want to become a “professional“ with the aim of becoming a so-called “professional“ such as teaching diver training yourself or wanting to be an underwater diving guide. On the other hand, those who want to receive professional education and acquire the knowledge and skills of a diving instructor level. The SSI education system can meet both needs.
