1. Exclusive access — Japan is 'a thing in itself'. Proxies are necessary for accessing games, anime services, and auctions (Yahoo! Auctions, Mercari) that strictly block any non-Japanese IPs.
2. High-tech infrastructure — Japanese proxies feature minimal latency and connection stability, critical for gaming and high-speed trading.
3. Impeccable reputation — Japanese IPs are considered among the most reliable in Asia, minimizing security checks and CAPTCHAs.
