depend on your settings. Basically VPN was created to guarantee secure access to remote workers but if " they " want you can use all the type of security ( VPN, Proxy etc. ) but they can found you. The other face of the medal is that if u use that only to " pirate music/video/games etc. " they will not spend time and effort to found you, cause the process to found someone with this security feature is not fast.

If so, that'd be nice. But recently there was news about a Japanese man getting caught due to sharing an HQ rip/camrip of Kimi no Na wa online. He had been tracked by the police several months before getting arrested at home. So I think it's not worth the risk if using a Japan IP as an exit node just to get involved with piracy.

why use a japanese ip ? use something in east europe, it's hard for them reach u cause for the local laws . There is a reason if basically everyone use bulgarian proxy ! btw if u want to have 0% risk so just do not do it!
