This study compares Facebook users in Japan, the US, and Taiwan, and users of similar SNSs in China, focusing on their self-disclosure and network characteristics. An online questionnaire survey was conducted in these four countries in 2012/2013. Results indicate that mobile device users use SNS more frequently than desktop/laptop PC users. Results also indicate that cultural differences in SNS use were observed. Across these four countries, the Japanese have the smallest number of Facebook friends; the highest level of homogeneity in their friendship network; the highest proportion of offline friends; are least likely to disclose personally identifiable information; and most frequently read and post messages on Facebook. In contrast, the Chinese are most likely to disclose personal attribute information and Taiwanese are most likely to disclose personal information on SNS. The Japanese also show a positive and significant correlation between network homogeneity, number of Facebook friends, and disclosure of personal information, which suggests that they depend on offline homogeneous relationships more than SNS users in other countries for their Facebook friending process. Structural equation model results indicate that cultural differences in self-disclosure on SNS between Japanese, Taiwanese, and Chinese users are partially explained by relational mobility.
