The use of Virtual Private Networks (VPNs) is currently legal in Japan. There are no specific laws that prohibit individuals or businesses from utilizing this technology to secure their internet connections or protect their online privacy. The country maintains a free and open internet environment, distinguishing it from neighbors with strict censorship. Residents and travelers can freely download and install VPN software on their devices without fear of legal repercussions, provided the technology is used for legitimate purposes.
The Japanese government acknowledges the importance of VPNs for cybersecurity. The Ministry of Internal Affairs and Communications (MIC) has published guidelines for small and medium-sized enterprises that explicitly list VPNs as a recommended security measure for telework environments (1). This official endorsement highlights that the technology is viewed as a tool for protection rather than a threat. Companies are encouraged to use these secure connections to safeguard sensitive data when employees work remotely, reinforcing the lawful nature of the software.
"There are few obstacles to internet access, no blocks on websites, and the legal framework provides strong protections for various forms of expression. Concerns over government surveillance of electronic communications persist, however, and women and individuals belonging to certain minority groups continue to face disproportionate levels of online harassment."
International organizations also recognize Japan's commitment to internet freedom. Reports indicate that the nation imposes minimal restrictions on digital access and respects user rights (2). However, it is crucial to understand that while the tool itself is legal, using it to commit crimes remains prohibited. Engaging in activities such as copyright infringement, hacking, or accessing illegal content is punishable by law, regardless of whether a private network is used to mask the user's identity.
