Nice footage, thanks for sharing - though, if I may be so cheeky, (as I often am), I'd love to have seen a video of the whole storm, taken from a very quiet spot, in one stationary shot from birth to waning so I could relax to it. :) 1hr possible in those storms? Also, how frequent (or infrequent) are they there in Japan?
Well, if and when you're out there,. maybe try and get one or two, pretty please? :) I'd love a 2-3hr looped (seamlessly) video to just chill out to. I'll like and share the video for you if you want - you only need ask or give me permission and I'll gladly do it for you. :)
