Why use a Kōshi residential proxy?
Every request through a Kōshi residential proxy carries a real Japan IP address, so websites treat you as an ordinary local visitor. That authenticity is the whole point: datacenter proxies share known hosting ranges that anti-bot vendors block on sight, while residential IPs from Kumamoto, Japan homes carry the trust of a normal broadband subscriber. For any task that depends on looking local in Kōshi — from price scraping to ad checks — that difference decides whether you get clean data or a wall of CAPTCHAs.
