For rural areas suffering from depopulation, it can only be good news if city-folk want to move to the country.

Over the past decade, countryside municipalities have used so-called U-turn and I-turn policies to encourage migration from the cities -- the key to success, it seems, lies in making detailed information available about the locality, and the jobs on offer.

"U-turn" and "I-turn" are the names given to two patterns of town-country migration. A "U-turn" is when an urban worker chooses to return to his or her native prefecture, while an "I-turn" is not really a turn at all, but describes a one-way movement from the city to the countryside.
