Oh Steve!
So sorry it’s so cold there. Honestly the nearest international Airport is Toyko, then you would have to get a flight to Okinawa. It’s even cold this time of year on mainland Japan. Luckily we are on the main island of Okinawa. There are many smaller islands around great for diving also. We went on a night Dive with Blade I think it was Wednesday Night. He posted some pics. They were great. Our camera, not as good. Something I plan to change soon. The temp at the time we went in was 68 F. We had 3 mm suits, gloves, boots, two of us had hoods. The water was great, vis was good. It was cold when we got out, but we entered at sunset and came out after sundown. We and cold hit quick stepping out of the water. But honestly it wasn’t bad. And I’m not one for the cold. We just took the wet stuff of quick and dried off. So all was well. We loved every minute of it. I know it gets colder in January. Might have to consider a 5mm, but I’ll wait and see. Not going to waste the money if I don’t need it. I’m going to pick up another tank, my first is an alumni I one, going to get a steel one.
So I’m sure you are taking advantage of the slopes. Enjoy the cold. Hope you get out this way, or to anyplace to get some diving in.
Keep in touch.
