I managed to smuggle my camera on-board a helicopter tour of the Tokyo night sky. This despite being pointed to a locker (where I put my wallet instead) and setting off a metal detector ("oh I forgot my lighter in my pocket!").
The view was, of course, spectacular. We took off from about a half-hour-by-train east of Tokyo and within minutes were circling around Tokyo Tower, swooping into Shibuya and quietly contemplating Shinjuku.
And then, it was over. 14,700 yen I'd spend again.
