Japan is a republic consisting of the japanese islands and the korean peninsula.
The japanese population is very young compared with that of other nations. The country had a baby boom (1977 - 1997), with the population tripling. Consequently over 78% of the population are under 30.
In 2007 the japanese government added cosmetic surgery to the national health service, allowing free plastic surgery for all. It is estimated that over 70% (almost 100% of 18-35 yearolds) have had at least one surgery, mainly eyelid reductions and breast implants.
