What is concerning is this:
>Most people surveyed said they want to get married at some point.
This isn't delineated by gender, so I interpret it as meaning that Japanese men and women both want to get married -- but they aren't enough for each other.
>A booming industry surrounds Japan's growing condition of loneliness, a phenomenon at once quite particular to the Japanese, yet also a glimpse into a future where many people live atomized lives mediated exclusively through personal technology.
That modern philosophy tends to devalue (or rather not value) human relationships is the one thing I'm tempted to blame this on:

But that is probably personal bias creeping up. Working hours are the popular explanation, but there is an incongruity: most Japanese claim to want to have relationships, so if they thought working hours were the problem then why haven't they complained? And how could they fail to notice something so obvious? If housing prices are the problem, how does this occur when Japan's population has been in decline for forty years?
I've heard of this phenomenon (and similar ones in Western Europe) and I pick up and discard economic explanations like bottles of some alcoholic beverage. But the alarm in the back of my head says that our culture is the problem, and it just happens to be popular in Japan. If that's the case, things will get worse, not better.
