Japanese students and video games

Every country/government does what's best (in their opinion) for their country to rake in money from other countries. A perfect example are tourist cities. Egypt puts a lot of effort in showing off the Giza plateaus, Europe is entangled in a giant railroad to take people from one country to another. There's also importing and exporting goods. Since Japan is 'known' for their technologies, gaming and animu, it would make sense that they spent so much time developing their goods and products despite the fact not many Japanese people actually use the product. Like how modern Egyptians don't bother to spend lots of money to tour the pyramids; it's a tourist attraction for the sake of nation profit from other countries.
