Globalization has brought many countries together. It is critical for governments to be able to adapt to rapid technological development on a daily basis. Technology makes people's life easier, yet it is debatable whether all countries are responding to these developments. Industry 4.0, which Germany pioneered, is discussed, while Japan, which is at the forefront of digital technology, is remembered for its Society 5.0 concept. The procedure of complying with Society 5.0, which was designed by Japan, might be in the fastest developing countries. The goal of Society 5.0 is to increase people's quality of life by ensuring that society is integrated. The integration of financial markets in developed countries with the greatest potential for transitioning to Society 5.0 was examined in this study. Eight developed countries are used in the study. The aim of this study is to analyze financial integration by addressing the index of countries with the highest potential for transition to Society 5.0, which Japan has put forward. The correlation coefficient is used in the analysis. In this framework, data for the years 2015-2020 has been utilized. It has been investigated whether the crisis or change in the financial system of any country has affected other country markets through financial channels. Among the countries identified, the reasons why countries with high correlation coefficient and weak are strong or weak are discussed. The digital development and technological developments of Society 5.0 have resulted in rapid adaptation of technological developments, making integration in developed countries faster.
