Japan IT Tender Signal — 官公需 IT入札・プロポーザル新着

What is Japan IT Tender Signal for?

Every weekday, Japanese ministries, agencies, prefectures and cities publish 200–300 procurement notices that mention "システム". Most of them are buried in PDF announcements on thousands of separate websites. This Actor reads the official 官公需情報ポータルサイト API (the Small and Medium Enterprise Agency's nationwide portal that aggregates those announcements, national and local), applies a built-in set of IT queries (system development, cloud, software, network, servers, data platforms, AI/RPA, DX, websites, security, IT maintenance, GIS), drops building-equipment noise, extracts deadline, opening date, budget ceiling and qualification grade from the notice text, flags proposals (プロポーザル / 企画競争), and in monitor mode returns only the notices it has not shown you before.

Typical users:

• IT vendors and SIers selling to the Japanese public sector who want every new system, cloud or website tender the day it appears, with the deadline already parsed.
• Bid-management and GovTech teams feeding a CRM or Slack channel.
• Analysts and journalists tracking government cloud (ガバメントクラウド) migration, DX spending or AI adoption by municipality.
• AI agents that need a JSON feed of Japanese public IT opportunities without reading PDFs.

Data source: 官公需情報ポータルサイト (https://www.kkj.go.jp/) API, an official service of the Small and Medium Enterprise Agency. Its terms require this credit and moderate access; the Actor paces its calls and includes the credit in every record.

}

The first record of every run is a summary with counts per prefecture and government level, top organisations, how many notices have a parsed deadline or budget, and per-query hit counts.

What you get

Field	Meaning
key	Portal's unique key, stable across runs
title, organization, prefecture, city	件名・発注機関・都道府県・市区町村 as registered by the portal
issueDate	公告日 (YYYY-MM-DD)
category, procedureType, certification, location	物品/工事/役務, 入札方式, 入札資格, 履行場所 (sparsely filled by the portal)
sourceUrl, fileType, attachments	The announcement page or PDF and any attached 仕様書 / 要領
deadline, openingDate	提出期限 and 開札日 parsed from the text (令和 dates supported)
budgetJpy	予定価格 / 上限額 parsed from the text, in yen
qualificationGrade	等級 (A–D) when stated
isProposal	プロポーザル / 企画競争 / 公募型
governmentLevel	national, local or other (rule-based from the organisation name)
matchedQueries	Which of your queries hit this notice
descriptionExcerpt / fullText	Notice text excerpt (default 1,200 chars) and optionally the full text
change	new (monitor mode), baseline or snapshot
llmSummary	One-line Japanese summary for LLM agents and alerts

Parsed fields are best-effort: in tests about 75% of notices yield a deadline, 60% an opening date and under 10% a budget (most notices do not state one). Always confirm with the linked announcement.

Settings

Input	Default	Notes
useItPreset	true	12 built-in IT queries

minBudgetJpy	–	Minimum parsed budget
daysBack	2	Window on 公告日 (1–30). The portal registers notices about one day after publication
descriptionChars / includeFullText	1200 / false	How much notice text to include
mode, watchlistId, emitBaseline, maxNotices	monitor / default / false / 2000	See below

Monitor mode, watchlists and the free first run

1. Choose a watchlistId (e.g. tokyo-cloud) and your filters. Run once. The first run is a free baseline: the Actor remembers the notices currently in the window and returns only a summary (no notice records are charged) unless emitBaseline is on.
2. Schedule the same input daily, ideally after 20:00 JST (the portal's collection batch runs around 19:00 JST). Each later run returns only notices published since the last run and charges only for those.
3. Different watchlists keep separate memories. Changing filters starts a new baseline for that watchlist.

Pricing: one run-summary event per non-baseline run, one notice event per notice record.

Example: cloud and system tenders in Tokyo and Kanagawa, proposals included

{
  "useItPreset": false,
  "queries": ["クラウド OR ガバメントクラウド", "システム AND (構築 OR 更改 OR 移行)"],
  "prefectureCodes": ["13", "14"],
  "daysBack": 3,
  "mode": "monitor",
  "watchlistId": "tokyo-kanagawa-cloud"
}

Notes and limits

• The API returns at most 1,000 notices per query and has no paging. When a query exceeds that, the Actor re-runs it per block of prefectures; very broad single words (e.g. just システム) can still be capped, so prefer AND expressions.
• The portal collects announcements one day after the issuing body publishes them; weekends have no new data.
• Some titles are PDF headings (e.g. a date) when the issuing body's page had no proper title; the excerpt and sourceUrl still identify the notice.
• Notices are official public records provided as-is. 本Actorは官公需情報ポータルサイトのAPIを用いています。
