There doesn't seem to be much relationship between porn consumption and amount of children. Lack of children seems to be due to economic factors. Keep in mind, a fertility rate of 2.10 (children per woman) is required to keep the population stable. That is called the replacement level fertility rate. So all industrialized countries would be seeing population decline if not for immigration. As you can see, Japan's situation isn't as dire as some other countries in Europe, most notably Portugal. The main difference with Japan vs most other countries is the lack of immigration.
