VPN (or other gifts) for student going abroad?

My son will be spending spring semester in Japan. In googling gift ideas for students studying abroad, I came across the suggestion of a VPN service. I am not sure how much he uses the family Netflix subscription, but that is one thing it would allow him to access. I know Japan is pretty safe as far as physical crime goes, but I don’t know about identify theft, etc.

Any opinions on the wisdom of a VPN service? Any other gift ideas? Or even tips for living in Japan for five months! (He will be at Kansai Gaidai University.)
