`japan_tenders_search`

Pack: japan-procurement · Endpoint: https://gateway.pipeworx.io/japan-procurement/mcp

Search Japanese government tender notices (bid announcements) by keyword across national ministries, all 47 prefectures and municipalities. Sourced from the 官公需情報ポータルサイト (Kankoju public procurement portal) run by the Japan SME Agency. Query accepts Japanese or ASCII text and the portal’s operators: “A AND B”, “A OR B”, “A ANDNOT B”, “NOT A”, parentheses. Filter by category (goods/works/services), prefecture, procedure type and announcement date range. Returns buyer organisation, notice title, announcement date, bid/opening dates where published, the original notice URL and attachment links.
