I can almost guarantee that if you haven't read the rest of this post your first reaction upon clicking that link will be to think I've lost my mind. The big ads for hot Japanese girls and hotels give it a particularly tabloid trashy look. What could be of interest here?
Quite a lot actually once your eyes adjust and you can focus on the text. Here you will find links to dozens of articles on just about everything Japanese, many of which are illustrated. Some are better than others, and most are drawn from other sources, but there is a lot of good information here.
Do you want to know how the Japanese celebrate Christmas? What a wedding kimono looks like? What is the climate like? Need a map of the country or of a particular city?
Here you go.
