On divorce in Japan

BBC NEWS | Asia-Pacific | Japan retired divorce rate soars

The article above notes the increasing rate of divorce in Japan amongst those married for 20 years or more. The reason is "retired husband syndrome":

Marriage guidance counsellors are warning newly retired couples not to spend extended amounts of time together - recommending day trips over cruises.

The author of self-help book "Why Are Retired Husbands Such a Nuisance?" said it is dangerous for a couple to go on overseas trips after the husband retires....

The BBC's Jonathan Head in Tokyo says many wives increasingly resent how little their husbands contribute to home life and are seeking divorce when, after retirement, the men show no sign of changing their habits....

Japanese people also tend to live longer, so when a man retires at 65 the wife may be thinking "I still have 20 or 30 more years with this person", our correspondent says.

I am sure that this is not unheard of in Western countries too. Has it been the subject of detailed treatment in a good movie in the last 20 years?

More off topic: While you are at the BBC website, have a look at this photo series about some homeless folk in Osaka. Seems the homeless in Japan are much more into self help than the homeless here.

This just made me think. Many of the homeless you see in Australia would appear to be that way due to drug or alcohol addiction and/or mental illness. In Tokyo, there are now a few homeless to be seen, mainly (in my limited experience) in train stations. (They make shelters to sleep in from cardboard boxes, but often are still "polite" enough to remove the shoes and leave them at the entrance to their cubby holes.) However, the homeless you see look more like economic refugees, as they do in that BBC report. Given that Japan does not exactly have a reputation for sympathy to mental illness, and given the huge population of Tokyo, where do those who are homeless due to mental illness end up? They don't seem to be on the street, and nor do chronic alcoholics (at least not in the daytime!)
