What happens as the population of elderly people rises and there are many older homes vacant as the population ages. This report in the BBC looks at the "ghost homes" in Japan that no one wants particularly in parts of the country and towns where many elderly people reside. These are also older homes that were build from wood in the old Japanese style making them more prone to collapse in earthquakes and fires. They are given almost for free with subsidies by town governments with few takers. A separate article this week shows China's median age rising. For the first time we see two large Asian societies, Japan and China experiencing or beginning to experience this problem.
