We are their partners. Japanese people want to pay for content. But if you create content that pleases the end user and that is of a high enough standard, they'll pay. All the popular mobile content is just entertainment. At first, this is true.
Entertainment helps to teach the user, especially if it's simple and easy to use.
Most users are office ladies and Shibuya kogyaru. No, and we have the stats to back this up. For instance, we've found that i-mode users are more or less evenly spread across people in their 20s, 30s, and 40s. Teenagers and people in their 60s use it less. Wireless is popular in Japan only because fixed Net penetration is so low.
