Japanese government will access home devices in security survey
This may seem weird, but I think the idea of what they're doing is spot on. If anyone were to get access to my things I'd rather it be the government and then have them disclose it to me. Additionally, if you don't want your information accessible you've had your notice to hire someone to lock it down or lock it down yourself. I would liken the service to the government checking the insulation on your house.
