Bezplatný seznam proxy pro Japonsko

We re-check the list every 15 minutes — speed, uptime, protocol response — but these are public open proxies aggregated from open sources, not servers under our control. We don’t run them, can’t guarantee uptime, and don’t collect logs from them. Free proxies churn fast: IPs disappear, get blocked, or stop responding with no warning. Treat this as a starting pool for code testing, one-off lookups, or quick checks of how a site responds to traffic from Japan. Anything that needs to keep running through the night belongs on a paid pool — these IPs aren’t built for sustained load.

Mercari (Japan’s #1 C2C marketplace) runs Akamai Bot Manager plus their own session-level fingerprinting — free public JP IPs hit hard 403/captcha walls within the first few requests. Yahoo Auctions Japan (still hugely active in Japan, unlike Yahoo elsewhere) applies aggressive per-IP rate limits and account-IP correlation checks. Rakuten Ichiba has multi-layered detection that varies pricing and inventory between domestic and international visitors. Amazon JP is moderate but still flags datacenter ranges fast. For sustained scraping of any of these, owned-subnet datacenter — FineProxy’s Japanese DC pool — handles individual product/listing pages with proper headers (Accept-Language: ja-JP, JPY cookie). The free list works for one-off price lookups, rendering checks, and pulling open data from .go.jp endpoints. For Rakuten specifically, also consider their official API as a more stable alternative to scraping.

Yes, significantly. Many Japanese e-commerce platforms (Rakuten, Amazon JP, Yahoo Shopping JP) detect non-Japanese IPs and serve modified catalogs: hidden products that don’t ship internationally, JPY pricing without Japanese consumption tax breakdown, no domestic-only campaigns or coupon codes, and sometimes entirely different category trees. For accurate domestic pricing intelligence you need an actual JP IP (free or paid) plus Accept-Language: ja-JP, plus JPY currency cookie. From a US/EU IP with ja-JP header you’ll get “international visitor” pricing — different product than what a Tokyo resident sees. Domestic context is non-negotiable for accurate JP retail data.

Modern Japanese sites are universally UTF-8, and the three scripts (kanji 漢字, hiragana ひらがな, katakana カタカナ) all live in the same UTF-8 string with no encoding tricks. Two practical considerations: full-width vs half-width characters (some forms accept only full-width digits ０１２ for postal codes; others reject them — normalize at submission time using NFKC if needed); and the small but persistent legacy of Shift-JIS on older corporate or government PDFs and a few legacy CMS installs (check Content-Type or BOM before assuming UTF-8). For pure browser-style scraping with proper Accept-Charset headers, modern JP sites send clean UTF-8 and decoding works without intervention.
