This paper argues social and cultural barriers to digital governance and the role of government to deliver public services online and engage citizen in the policy process in Korea. In order to argue the issue, the significance of digital governance as a mode of practice of good governance is discussed. Digital governance includes 1) digital government, 2) digital market, and 3) digital civil society. Even though Korea has much developed infrastructure for the digital governance, some barriers to digital governance still exist. While Korea has strong leadership and financial investment on digital governance, social and cultural barriers such as low trust in politics and low credit card acceptance may prohibit the development of digital governance as well as bureaucratic behavior and procedure. Moreover, good digital citizenship is essential to create values from the digital society. Based on the discussion, the appropriate roles of government to improve digital governance are briefly suggested.
