The most common diving style in Yakushima is a guided boat dive in the Isso area.Boats depart from Isso Fishing Port, and since the dive sites are only 3–5 minutes from the port, the boat returns to the harbor after each dive.Surface intervals of 40–60 minutes are taken on land at the port.The Isso area offers a variety of dive sites, and the day's diving locations are chosen based on the weather, sea conditions, and diver experience level.【Entry & Dive Conditions】Backroll entry from the boat.Each dive site has permanent buoys and ropes for easy entry and descent.Most sites have no strong currents, making them enjoyable for both beginners and experienced divers.【Daily Schedule】08:00 – Hotel pickup08:20 – Meet at dive site08:30 – Arrive at the boat08:45–09:45 – 1st dive09:50–10:40 – Surface interval at the port10:45–11:45 – 2nd dive12:00–13:00 – Lunch break at the port13:15–14:15 – 3rd dive (optional)14:45–15:15 – Shower & change15:15–16:00 – Logbook entry16:00 – Finish【Flexible Diving Options】You can dive once or twice in the morning, with an optional third dive in the afternoon (maximum 3 dives per day).Since the boat returns to the port after each dive, you can also choose to join only morning or afternoon dives.Depending on your arrival time in Yakushima, you can start from the 2nd or 3rd dive.If space allows, diving twice in the afternoon may also be possible.After the dives, you can shower and change at our shop in Miyanoura, where we also complete logbook entries before checkout. (Miyanoura is about 15–20 minutes by car from Isso.)If you don’t need to fill out a logbook or prefer to end your dive at the site, you can check out directly at Isso—just let us know in advance!
