Japan Proxies

Japan has a deep published pool relative to most catalogue entries. Use the Japan depth for measured country-level sampling, not for routing around a quota, challenge, or block. Long-lived Japan flows should prefer a documented sticky session; independent observations can request rotation. In both Japan modes, connection reuse and live supply can produce the same exit more than once. Japan pool depth also cannot authorize collection: the destination's terms, robots guidance, contracts, authentication boundaries, rate controls, and applicable law remain the controlling constraints. Treat a block, CAPTCHA, quota, or explicit denial as a stop or review signal across the whole Japan pool rather than rotating around it. Record Japan failures as data; do not hide them with unlimited retries.

The immediately larger Asia catalogue entry than Japan is Philippines at 613,557 addresses, and the next smaller is Bangladesh at 540,792. In the Japan comparison set, the regional leader is Indonesia with 2,664,464. These Japan capacity comparisons are useful only when the workload could legitimately run from more than one country. Choose Japan when the research question specifically needs a network-origin observation from Japan. Choose a different country from Japan only when it is a valid control or a separate market in the study. Combining Japan observations with other countries in one unlabeled dataset makes regional differences impossible to interpret. Preserve the requested Japan route, observed exit country, network type, timestamp, source, response class, and validation outcome on every retained record.

Before using a Japan result, capture five things: the canonical source URL and permission basis; the Databay network and countryCode-jp setting; the observed exit IP, ASN, and geolocation source; the browser, account, language, currency, address, cookie, and device state; and the UTC timestamp plus response evidence. Repeat the Japan check from a controlled reference and label missing, blocked, challenged, stale, or personalized responses instead of treating them as ordinary content. For a consequential Japan price, availability, advertising, search, compliance, or product decision, obtain a second authorized source or local review. This Japan workflow makes the 543,861-address catalogue figure useful as coverage context without pretending it proves a resident's experience.
