`japan_tenders_by_prefecture`

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

List Japanese government tender notices for one or more prefectures without needing a keyword — the way to browse what a given prefecture published recently. Sourced from the 官公需情報ポータルサイト (Kankoju public procurement portal, Japan SME Agency). Accepts a prefecture name (“Osaka”, “大阪府”) or JIS X0401 code (“27”), optionally narrowed by category, announcement date range and keyword.

Parameters

Name	Type	Required	Description
`prefecture`	string	yes	Prefecture name (“Tokyo”, “東京都”) or JIS X0401 code (“13”). Comma-separate for several. Codes are zero-padded for you — a bare “1” returns nothing upstream.
`category`	string	no	One of goods \| works \| services (or 物品 \| 工事 \| 役務, or 1 \| 2 \| 3).
`query`	string	no	Optional keyword to narrow within the prefecture.
`issued_from`	string	no	Earliest announcement date (公告日), YYYY-MM-DD.
`issued_to`	string	no	Latest announcement date (公告日), YYYY-MM-DD.
`limit`	number	no	Max notices to return, 1-${MAX_COUNT}. Default ${DEFAULT_COUNT}.
`full_text`	boolean	no	Return the full announcement text instead of a preview. Default false.
