Have you ever recharged your phone by plugging into an empty socket you've found in public? In case you weren't certain, this report from the Asahi (Japanese) confirms that you are breaking the law if you do. Last month, a college student plugged her charger into a spare socket inside JR Sagamihara station and was spotted doing so by a passer-by who called the police on 110. The girl was waiting for a friend and so was still at the same spot when the officers arrived. They pointed out that she was engaged in an act of theft but let her off with a caution. The report says the girl probably stole electricity worth 0.03 yen leading one officer to comment "it may only be a tiny amount but it's still stealing".
