Very Japanese, I certainly understand his position. I visited a datacenter just after new years for a quick task. They do not allow you to take laptops, phones, game consoles, USB memory or any sort of card memory (which is ridiculous), and they use airport-style metal detectors and a fancy full body scanner to check for such things.... as you leave.
So 5am on cold Sunday morning I go in, dump all my stuff in a locker and walk up to security - and they don't want to check me... I go in, do my work, come back out about 15mins later and I go through security and put my heavy leather jacket through the xray machine and they find I have my spare mobile phone in my inner pocket - completely dead since I don't use it that often. I say sorry about that, but I did want you to check me before going in. I show them that its dead, and doesn't have any memory, but they won't have any of it, the security guard grabs it, goes into the office and shuts and locks the door :auch:
Basically this ends with me shouting for an hour for my phone back, me being ignored by security, and me calling the police because I see this as theft of my personal property. In the end they give me the phone back and I gave them a short english lesson.
