I recently flew out of Narita, and security was so easy that I thought I missed it somehow. There were no lines and no herding factor. Nobody checked my boarding pass with a UV pen or even checked my ID. I just had to walk through an old-fashioned metal detector with my shoes, belt, and jacket still on. And they saw I had a camera bag and offered to hand-check my film without me even asking. And they were cute too. I thought this must be some preliminary carry-on bag security pre-check or something, but that was it.
