Latest update: April 2023 

Japan has been one of the leading countries in the commercial application of information and communications technologies since the early 1980s. Nevertheless, today the country is considered one of the weakest among the 15 main global powers when it comes to cyber self-defense, as argued by the International Institute for Strategic Studies in of its latest report. Cybersecurity – different from IT security in terms of purposes and operations – still seems to be an underestimated industry at the eyes of Japanese entrepreneurs and institutions, whereas many of the OECD member states have set investments in this area as a priority target.

Japan does have some potential strengths in a number of categories, but also shows significant weaknesses in others. Anyway, in the last decade Japan has been making efforts in this sense and has now a well-developed approach to the governance of cyberspace. The 2020s will be important for Japan as the world enters an era of a “new normal” and digital society.
