In line with the development of tourism, information technology in the coastal city of Manado is growing. This development has an effect on the change in function of the Bay of Manado coastline to become a favourite area for tourists. The entry of one million tourists from China to North Sulawesi helped drive changes in the coastal environment. This study aims to discover the implementation of government responsibilities in the management of tourism in the coastal areas of the Bay of Manado and to determine the inhibiting factors of the implementation of government responsibilities in managing the coastal environment. This research was carried out on the coast of the Bay of Manado. In this study, the type of data collected consists of primary data and secondary data. This type of research is quantitative using the analytical descriptive method. The process undertaken is to examine the data that has been obtained to ensure whether the data can be justified in accordance with reality. After the data is processed and deemed sufficient, it is then presented in narrative form and possibly also in tabular form. The results showed that the implementation of government responsibilities in the environmental management on the coast of the Bay of Manado was running less than optimally in terms of participation at the degree of consultation, and not yet at the degree of community control. It is clear that there are three factors which hinder the implementation of the responsibility of the Manado City Regional Government in the management of tourism in the coastal area; namely environmental, institutional, and community participation.
