Japan Proxy Network
Access the Japanese internet with premium residential, ISP, and mobile proxies. 6M+ IPs across 100+ cities.
Why Use Japan Proxies?
Japan is the world's third-largest economy and one of Asia's most distinctive digital markets. With over 100 million internet users and a highly developed e-commerce ecosystem anchored by Rakuten, Amazon Japan, Yahoo! Shopping, and Mercari, Japan represents a critical market for businesses operating across the Asia-Pacific region. Japanese platforms are notable for serving heavily localized content — pricing, promotions, and product availability on Rakuten and Yahoo! Shopping can differ significantly between prefectures, making genuine local IP access a prerequisite for accurate competitive intelligence.
NanoIP provides access to over 6 million Japanese IP addresses spanning 100+ cities across all 47 prefectures, from the greater Tokyo area and Osaka-Kobe-Kyoto (Keihanshin) to Nagoya, Fukuoka, Sapporo, and Hiroshima. Our Japan proxy infrastructure connects through Japan's leading broadband and mobile operators — NTT East (Flet's Hikari), NTT West, KDDI (au Hikari), SoftBank Broadband, OCN (NTT Communications), So-net, and Biglobe — ensuring authentic residential fingerprints and sub-100ms latency within Japan. ISP proxies use static addresses from NTT Business and KDDI Business ASN ranges, which carry high trust scores on Japanese platforms. Mobile proxies run on NTT Docomo, SoftBank Mobile, au (KDDI), and Rakuten Mobile 4G/5G LTE networks.

Using Proxies in Japan - Legal Context
Japan's primary legislation governing unauthorized computer access is the Unauthorized Computer Access Law (不正アクセス行為の禁止等に関する法律, Act No. 128 of 1999), which prohibits accessing computer systems without authorization but does not restrict access to publicly available web content. Collecting publicly available data through proxy connections for commercial purposes — including competitive price monitoring on Rakuten and Yahoo! Shopping, ad verification, and SERP tracking — is generally lawful in Japan, provided the activity does not involve circumventing technical access controls on private or subscription-based systems.
Japan's Act on the Protection of Personal Information (個人情報の保護に関する法律, APPI), most recently amended in 2022 with full enforcement from April 2022, imposes strict obligations on entities that handle personal information about Japanese residents. Key provisions relevant to data collection include purpose limitation (data may only be used for the purpose disclosed at collection), third-party transfer restrictions (personal data cannot be shared with third parties without consent or a lawful basis), and mandatory breach notification. Scraping workflows that capture identifiable personal data about Japanese individuals — names, contact details, purchase histories — must comply with APPI requirements.
NanoIP recommends all customers conducting data collection activities targeting Japan consult qualified local legal counsel, particularly if collected data includes personal information as defined under APPI. For standard commercial intelligence use cases involving non-personal, publicly available data, proxy-based collection carries minimal legal risk under Japanese law.
