Search Japan’s Ministry of Land, Infrastructure, Transport and Tourism (国土交通省) negative-information site (ネガティブ情報等検索サイト) for administrative dispositions against licensed businesses: construction businesses (建設業者) and real-estate brokers (宅地建物取引業者), such as an instruction (指示), a business suspension (営業停止) or a licence revocation (許可取消). Each hit gives the firm, its corporate number (法人番号), head-office address, the disposition date, the authority that issued it (a regional bureau or a prefecture), the action and the record link; ten rows a page, newest first, with the total match count. Firms with a corporate number only: sole proprietors are dropped and counted in skipped_possible_individuals. Search by the Japanese registered name (for example 大林組; the 株式会社 prefix is optional) and/or a month range (from, to as 2025-10); with neither, the last three months are listed and the answer says so. Zero matches states the list and period. Example: sector=“construction”, query=“大林組”.

Parameters

`sector`	string	no	construction (建設業者, default) or real_estate_broker (宅地建物取引業者).
`query`	string	no	Business name in Japanese (registered name; the 株式会社 prefix is optional). Optional.
`from`	string	no	First month of the disposition date range, YYYY-MM (2015 onward). Optional.
`to`	string	no	Last month of the disposition date range, YYYY-MM. Optional.
`page`	number	no	Result page, 1 (default); ten rows a page.
