Does anyone have recommendations for Snorkeling tours within 4-5 hours from Okayama/Chugoku? I'll be there for most of December.
Sidenote- Okinawa is way too hot for me, I need average high atmospheric temperatures to be under 15°C. I went scuba diving in Izu this January and the temperature (air & ocean) was totally fine with a wetsuit.
