More ways to explore the area's outdoor wonders
Dawn arrives over Isso Fishing Port with the boat engines murmuring and salt lifting off the water — a compact harbor that serves as the launch point for short, focused dives into Yakushima’s coastal reefs. Certified divers step from the quay, kit already checked, and make a backroll entry a few minutes offshore to explore sites chosen by the guide based on tide and visibility.

Bring your certification and logbook

Surface intervals are 40–60 minutes at the port; use that time to rehydrate and refuel for better bottom time and safety.
Expect backroll entries
Boat dives use backroll entries and fixed ropes — practice stable entry and weight checks before heading out.
Check weather and tide
Dive sites are chosen daily for conditions; confirm pick-up and contingency plans the night before.
Mask, snorkel, fins
Personal optics and fins ensure fit and comfort during dives and surface swims.
