Myanmar, which is struggling as a developing country, most of the government offices are still running in paperwork because of inadequate infrastructure: technology, skilled human resources, budget, etc. Except for a few amounts of private companies and banks, most of the private business is not well connected with internet network yet. Banks are struggling to get the trust of the people on their e-banking systems which are initiating their services among many system errors. However, if we compare with last ten years ago, the growth rate of the population who use smartphones, computer, and other IoT devices are rapidly increasing because of privatization and liberalize the Myanmar telecommunication sector(DUJACQUIER, 2015). After starting transformation as a democratic country, the people are demanding the government to be more transparency and accountability without corruption. New civilian government is striving to get easy access to the people and government services by developing e-government system as ruling NLD Party promised during the election camping. Private companies are also facing new challenges in the newly opened economic system. They need to compete with the foreign companies especially in customer services more actively by using wired and wireless communication systems.In the rapidly changing environment, the country is necessary to develop systematically in cybersecurity and critical information infrastructure protection sector in line with the international standard which is practicing in the rest of the world. The interest of the paper is analyzing how much the gap between the developed world and one of the most recent opened country, Myanmar in critical information infrastructure protection sector. In this paper, Japan was chosen as one of the most advanced countries in cybersecurity sector to be able to compare how much huge the gap of the technology development and readiness to protect the risk of the cyberspace between the two countries.To be able to create a complete policy recommendation, the paper will be basically descriptive, exploratory and comparative study especially with critical infrastructure protection in other developed country, Japan. Books, documents from online sources and lecture notes of the instructors in Physical and Cybersecurity Course of the Graduate School of Public Policy, the University of Tokyo are used to collect data and information. Basically, it will be a qualitative paper intended to give policy recommendation for Myanmar government based on the lessons and experiences of Japan government in critical information infrastructure protection sector.1. Japan, an advanced world and Critical Information Infrastructure ProtectionFor the sake of being a technology advanced country, many sectors are running based on the internet network. According to the National Center of Incident Readiness and Strategy for Cybersecurity(NISC), thirteen sectors are running as critical infrastructures: information and communication, financial, aviation, railway, electric power, gas, government services, medical, water, logistics, chemical, credit card, and petroleum in Japan(NISC, 2017).1.1 ChallengesNot only private sector companies and organizations but also public sector organizations have experienced cybersecurity threats and problems. The number of cyberattacks are increasing in all sectors day by day(KINGSTON, 2016).
