About this tour
When Ben from our team tried this dry suit diving course in Kushimoto, Wakayama, we got a proper introduction to staying warm and controlled underwater. The experience pairs a beach dive with a boat dive, letting you practice buoyancy and comfort in cooler water under an instructor's eye. Kushimoto sits in the rare zone where Japan's northernmost coral reefs thrive — so you're diving in genuinely interesting conditions, not just a training tank. The whole thing takes seven hours, and it's built for certified divers ready to level up rather than absolute beginners.
Highlights
- Two dives in one day — beach then boat — builds real dry suit confidence
- Kushimoto's coral reefs are unique to northern Japan; genuinely good underwater scenery
- Buoyancy control practice in realistic conditions with proper instructor feedback
- Full dry suit kit included; no hunting for cold-water gear elsewhere
- Private transport baked in; reduces logistical friction on the day
- Calm, focused teaching style — instructor watches your technique closely
- Beach dive settles nerves before the boat leg
What to expect
You'll start the morning gearing up at the dive shop — Ben found the staff patient and thorough when explaining dry suit mechanics and how to manage buoyancy differently than in a wetsuit. The beach dive is shallow and sheltered, giving you space to dial in your weighting and trim without rushing. It's the rehearsal that matters; expect to spend real time hovering and fine-tuning rather than rushing through a checklist.
After a break, the boat dive pushes things further. You're in the water longer, dealing with slightly deeper water and real conditions. The instructor keeps close watch, stopping you mid-dive if something's off with your positioning. Kushimoto's reefs are genuinely colourful — soft corals, small fish life, the works — so the scenery rewards your focus. By day's end you'll feel markedly more at home in cold water and the gear feels less alien. It's not a speed-through; it's deliberate practice.

Good to know
This is worth your time if you've already got diving basics down and want to push into cooler water without the guesswork. Divers in their first year post-certification, or anyone planning trips to colder regions, will get solid value. The package includes all equipment and transport, so you're not juggling extras. Kushimoto itself is lovely — rural, quieter than touristy diving spots — so you get skill-building without crowds.
Seven hours is a decent block; check your schedule before booking. You'll be in water twice, so cold tolerance matters — even in a dry suit, prolonged immersion in cooler seas isn't for everyone. Lunch isn't provided, so bring snacks or plan a nearby café. The course rules out anyone with spinal injuries, pregnancy, or cardiovascular concerns; be honest about fitness. Walking and gear hauling are moderate but steady. Best in calm seasons; winter winds can disrupt boat diving. Public transport exists nearby if you want to skip the provided pickup.
