My son Mike has a thing about ruins. Japan- where he lives- is dotted with abandoned buildings- some from the boom years, some much older. Where we'd call in the demolition men- or strip out the insides and build luxury apartments- they just walk out the front door and leave the premises to rot- often with the furnishings intact. They've got a name for these hulks; they call them haikyu. Mike explores haikyu- and blogs about them- and on Saturday he got a very tasty review in the Guardian.
