Our island of 602 people has a PA system that is used to make important public announcements. While these announcements usually concern typhoon warnings, ferry cancellations and funeral announcements, the PA system is not limited to these. Temple ceremonies are announced too, such as Buddha's birthday and the anniversary of his passing into Nirvana.

But last week for the first time ever, I heard a very unusual announcement.

"Shiraishi Island residents, may I have your attention please. Two men in suits are driving around the island in a car and knocking on doors. We consider this shady activity. Know your rights as a citizen and do not let them inside your house."
