The weight would be the problem there as you said. Amatsu is basically a flying Lagiacrus with (bigger) fins instead of horns. Don't really think those add up that much to his overall body weight (and man... how puny would he look without the fins making him look twice as big than he is?).

It's gotta be something along the lines of blowing wind below himself as you said, but even then, you'd need winds far more powerful than an average Hurricane to lift such a big boy up. I don't know what he'd be but if you may assume anything going by IRL reference material you can almost surely say a dozen of a ton. :/
