Japanese Old People

How screwed up is Japan demographically speaking?

In Japan:

1. More adult diapers than baby diapers are sold.
2. There are more elderly shoplifters in Tokyo than there are teenaged ones.
3. Old people on farms have twice the voting power of young people in cities.

Numbers 1 and 2 will probably get all the derision, but it is #3 that actually causes problems for Japan.
