Oops 4:12 you said 1100 dollars, not yen, yikes! (Edit: you seem to spend so much time in Asia you must be thinking in Japanese when you go there. Maybe back in the U.S. the first thing you say is Kon'nichiwa)
You rock! If the zip line is 1000 yen that's only seven dollars USD. Heck yeah, if you're that close! Great footage. Perspective. Even sound with the creaks!
To be able to stop at one place and get footage despite that massive foot traffic, on a day with so, so many crowds - that's not just luck! Someone is quite the traveling pro!
