Source and rights position
5channel Data Services is operated by the operator of 5channel. Data is licensed as a first-party offering from the entity that operates the source system — not resold, aggregated from third parties, or assembled by crawling.
This matters for diligence: there is one counterparty, one chain of custody, and one contract governing the data you receive.
Nature of the content
The corpus consists of posts submitted for public display on a public discussion board. It is user-generated content. Posts are made under pseudonymous or anonymous conditions and were publicly accessible at the time of posting.
Licensees remain responsible for their own compliance assessment, including under the Copyright Act and the Act on the Protection of Personal Information. We provide documentation, provenance records, and configurable processing to support that assessment; we do not substitute for it.
TODO(legal): entire licensing page requires review by Japanese counsel before launch. Do not publish without sign-off.

Redaction is applied deterministically and is recorded in the delivery manifest. Custom profiles can be defined for a specific engagement. No redaction process is represented as achieving complete removal of personal information.
