A VPN is a way to mask an online user's physical location, which is a great way to maintain privacy and security....while also allowing one to watch TV & Netflix in another country (Japan)! VPNs do what "incognito modes" in browsers don't. However, you don't want to sign up for a super low-cost or free VPN service, as those can be quite suspicious. They have to be making money somehow, and it is likely by selling user information (sort of the antithesis of what VPN users want). If you're looking for a virtual private network, go for an audited, secure brand with reasonable/legitimate pricing.
