Outside of print material, entertainment tends to be much pricier in Japan than compared with the states. I've heard various reasons as to why (pricey duplication methods, small print runs, too many limited edition goodies, the people don't care, the economy can handle it, it's a big scam, etc.), but I don't know if it's one or more of them. Typically games cost $60-$100 US dollars, DVD's $40-90 US, and CD albums $20-30 US. Used shops get a lot of business there too (who can blame them?), so that could also be a factor.
