VPN

• 読み: ブイピーエヌ
• ローマ字: bui pii enu
• 発音: /bu.i piː e.nu/

意味

Virtual private network; used by Japanese internet users to access geo-blocked content, protect privacy, or bypass regional restrictions.

VPN (read as ブイピーエヌ in Japanese) became widely discussed among Japanese internet users as geo-blocking on streaming services and privacy concerns grew. Common use cases include accessing overseas Netflix libraries, staying secure on public Wi-Fi, and working remotely through a corporate VPN. While technical users have long known VPNs, the term entered everyday conversation in the 2020s as consumer VPN apps became mainstream.
