    Frequently Asked Questions Q&A for Beginner Divers

    Family-Friendly Water Activities in the Waters off Amami Oshima

    Here we have compiled a list of frequently asked questions from first-time visitors.

    Q. Do I need a license for my first dive?
    A. No, you do not need a license. Amami Oshima Island offers a "trial diving" course, where a professional instructor will dive with you from start to finish. You can practice ear removal and breathing techniques before entering the water, so there is no need to worry.
    Q. How much does it cost to dive in Amami Oshima?
    A. For experience diving, the standard price is around 15,000 yen per dive. A two-dive course on a boat costs about 20,000 yen. Many plans include equipment rental, guide fee, and insurance, so you do not need to prepare much in advance.
    Q. What equipment and personal belongings should I prepare?
    A. Basic equipment (wetsuits, masks, fins, etc.) can be rented at most stores. During periods of strong sunlight, a rash guard and hat are also useful. If you bring a waterproof case for your cell phone, you can enjoy taking commemorative photos after diving without worry.
    Q. Can I dive even if I am not a good swimmer?
    A. Of course it is possible. Diving is said to be more of a "floating" sport than a "swimming" sport. Instructors are always nearby to watch over you, so if you feel scared, they will support you immediately.
    Q. Is it okay if I've never dived before?
    A. Yes, Amami Oshima is especially well-suited for first-timers. In fact, about 90% of the reservations for our Amami diving tours are for trial and beginner-friendly plans that don’t require a license, and the majority of participants are either “first-timers” or people who “haven’t dived in a while.” We keep group sizes small so an instructor is always right by your side, and we make sure you thoroughly practice ear equalization and breathing techniques before entering the water. Diving is an activity that feels more like “floating” than “swimming,” so you don’t need to be a strong swimmer. You’ll start in shallow waters where you can touch the bottom and enjoy the world of “Amami Blue” at a comfortable pace.
    Q. Can I enjoy diving in winter?
    A. Yes, you can dive in the Amami Sea in winter. The water temperature drops slightly to around 20 degrees Celsius, but if you rent a dry suit, you can dive comfortably without worrying about the cold.
