Tomoko Houtzager isn't living entirely off the grid, but in many respects she's not far off it.
Originally from Yokkaichi, a city in Mie Prefecture, Houtzager has been living on a 130-acre farm in New South Wales, Australia since 2004.
The sprawling farm, more or less the same size as Ueno Park in Tokyo, is within reach of three national parks, all of which are registered as World Heritage sites.
