据日本媒体报道，截止今年九月，GREE、DeNA、Mixi这三大日本社交平台的注册用户人数已超过6500万，比今年初增长了40%。这三大网站均支持用户的资料分享、信息交流等社交活动，据称它们今年的营收也创下了一个新纪录。

在这三者中，GREE和DeNA尤其擅长运营手机游戏网站，支持手机用户通过免费游戏进行互动。据游戏邦了解，GREE至九月份的注册用户已达到2246万人，其次是DeNA公司旗下的Mobage-town平台，拥有2167万用户。

Mixi所提供的SNS服务主要支持用户之间的交流，目前共有2161万注册用户。

游戏邦认为，随着Facebook进驻日本，在当地设立了子公司，日本SNS市场必将持续快速增长。

不过当地的SNS最近也惹了不少麻烦，不少手机用户抱怨自己在游戏过程中被不明不白地多收了许多费用，而他们事先并不知道有些游戏道具属于付费功能。

据日本全国消费者事务中心（National Consumer Affairs Center in Japan）的资料显示，今年4月至11月份，该中心总共收到439次关于免费在线游戏的投诉，比去年同期增加了40%。其中有四分之一的投诉人是20岁以下的游戏用户，甚至还包括一些在校小学生。（本文为游戏邦/gamerboom.com编译，转载请注明来源：游戏邦）

Social networking service users top 65 mil at 3 major sites

The number of social networking service registrants at three major Japanese operators topped 65 million as of the end of September, a jump of around 40% from a year earlier, as they provide diversifying services. The three major providers—GREE Inc, DeNA Co and Mixi Inc—have also renewed their records in revenues, amid the growing popularity of the service designed to enable Internet users to share their profiles, build social networks or relations and exchange messages.

Of the three, GREE and DeNA have been particularly successful in operating mobile game sites, which provide mobile phone users with charge-free games and allows them to communicate with each other through the games.

GREE had the most number of registrants at 22.46 million as of the end of September and DeNA, operator of popular Mobage-town mobile game site, the second-most at 21.67 million.

Mixi, the pioneer in the market which is better known for offering SNS as a communication tool, had 21.61 million registrants.

The SNS market in Japan is expected to grow further with the establishment of a Japanese subsidiary of Facebook Inc, which has 500 million active users around the world.

Meanwhile, troubles related to SNS have also increased. Some users of the mobile phone games said they have been charged high prices for using tools in the games, without knowing that the tools cost money.

According to the National Consumer Affairs Center in Japan, it has received 439 complaints between April and December this year in connection with free online games, up 40 percent from the same period the year before.

About a quarter of the complaints were in relation to the use of such games by those below age 20, including elementary school students.（source:japantoday）
