Friend you’ve worked very hard! Definitely Mount Ōdaigahara is not a joke. I wonder, why didn't you get hydrated and fed during the climb? Thank you for sharing!
Alex, thank you for your comment. I used FDR-X1000V made by SONY. Although this camera has already been out of production, FDR-X3000 is now state-of-the-art action cam. www.sony.com/electronics/actioncam/fdr-x3000-body-kit
