The effect of seismicity in earthquake-prone areas is soil liquefaction. This common geohazard that usually occurs in the world induces fatality damage to buildings and infrastructure. Consequently, preventive effort is required to avoid this condition's harmful effects. Two countries that have outstanding seismic records and soil liquefaction damage histories are Japan and Indonesia. However, liquefaction research in Indonesia is not fully developed yet to assess the liquefaction vulnerability as the mitigation countermeasure as Japan did. This paper aims to generate potential proposals in soil liquefaction research between Indonesia and Japan that will be able to expand in terms of disaster prevention. A bibliometric analysis with Vosviewer was conducted to provide a lot of potential topics in soil liquefaction. Moreover, the research data from the Scopus database was analyzed to list the similarities and differences topics between the two countries. Moreover, comprehensive methods such as empirical, semi-empirical, and computational analysis have been widely mentioned and discussed between the results of the two countries. The results indicate that Indonesia's liquefaction susceptibility analysis should consider Japan's research categories. The research's main contributions are highlighting the many applications of soil vulnerability research in Indonesia and Japan, indicating possible areas of research that have not been explored, and summarizing the exciting possibilities for future research in this subject.
