The Year of the Tiger won't be as black and white as 2009, the Year of the Cow. But with the Tiger leading, it may be a year that promises more golf, sex and misadventure, which you have to admit, is something.
Although Japan often laments the decline in population that has resulted from (among other things) more females in the workforce and people marrying later in life, I've often thought Japan's declining population was due to something much more basic.
Japan continues to rank near the bottom when it comes to sexual activity between married couples. In addition, "sexless marriages" can only mean a decline in population. Japan is just not a romantic country.
