How Japanese procurement is published
Japan does not have one single procurement website the way some countries do. Instead, several channels work together. The Kanpo (官報) — the official government gazette — is the legal-of-record where tender notices are formally published. Electronic procurement for central-government bodies runs mainly through GEPS (the Government Electronic Procurement System, 電子調達システム), where suppliers receive documents and submit bids. And the JETRO Government Procurement Database — maintained by the Japan External Trade Organization — aggregates WTO-GPA-covered notices in English specifically to help foreign suppliers participate.
On top of these, individual ministries, agencies, independent administrative agencies (独立行政法人), and local governments (prefectures and municipalities) operate their own procurement pages and systems. So the practical map is: above-GPA central-government notices are visible in English via JETRO and transacted via GEPS; everything else is in Japanese across a patchwork of ministry, agency, and local-government sites.
What you find in these channels:
- Invitation to tender — open and designated competitive bidding notices
- Advance notices — early information on planned procurement
- Specifications (仕様書) — the technical requirements document
- Award results (落札結果) — winner and contract value disclosure
- JETRO English summaries — for GPA-covered notices
Key fact
Japan is one of the world's largest public-procurement markets, with central and local government spending running into the hundreds of trillions of yen annually across all levels. As a major WTO-GPA party, Japan opens a substantial slice of central-government procurement to foreign suppliers — and JETRO exists specifically to help them find and bid on it.
The Unified Qualification
The cornerstone of bidding for central-government work is the Unified Qualification for Participating in Tenders (全省庁統一資格, zenshōchō tōitsu shikaku). Rather than qualifying separately with each ministry, a supplier applies once and receives a qualification accepted across all central-government ministries and agencies.
The qualification is granted per business category — manufacturing (製造), sales (販売), services (役務), and others — and assigns a grade of A, B, C, or D based on factors such as capital, turnover, and operating history. The grade then determines the size band of contracts you are eligible to bid on: A-grade suppliers can bid on the largest contracts, D-grade on the smallest. Foreign suppliers can and do obtain the Unified Qualification, which is the gateway to open competitive bidding at central level.
Tender methods and thresholds
Japanese procurement uses several methods depending on value and complexity:
- Open competitive bidding (一般競争入札) — the default for GPA-covered, above-threshold procurement; any qualified supplier may bid.
- Designated/selective bidding (指名競争入札) — the buyer invites pre-selected qualified suppliers; used below GPA thresholds.
- Discretionary contracts (随意契約) — negotiated/sole-source for limited, justified circumstances.
- Comprehensive evaluation bidding (総合評価落札方式) — technical merit scored alongside price, rather than lowest-price-wins.
Thresholds follow the WTO-GPA, expressed in SDR and converted to yen each two-year cycle:
| Contract type | Approximate GPA threshold | Effect above threshold |
|---|---|---|
| Central-government supplies & services | ~ 100,000 SDR (tens of millions of yen) | Open competitive bidding; English notice via JETRO |
| Construction (central) | Several million SDR | Higher threshold; GPA rules apply |
| Sub-central / covered entities | Higher SDR figures | Prefectures, designated cities, covered enterprises |
Figures are indicative — verify the current yen conversion for the relevant period before relying on them.

How to register and bid as a foreign vendor
- Apply for the Unified Qualification in your relevant categories — this is the prerequisite for central-government open competitive bidding.
- Register on GEPS and obtain the electronic certificate needed to download documents and submit bids electronically.
- Monitor the JETRO database for English-language GPA-covered notices, then cross-reference the full Japanese specification.
- Prepare for Japanese-language documents — even GPA-covered tenders typically have the full specification (仕様書) in Japanese; bids and clarifications are usually in Japanese.
- Provide bid security where required — bid bonds and performance bonds are common on larger contracts.
- Consider a local presence or agent — practically important for delivery, language, and relationship-driven evaluation.

Hook lets you search Japanese tenders in plain English — semantic matching finds the right notice even when the Japanese title and specification use terminology you don't read.
Hook monitors Japanese procurement for you
Between the Kanpo, GEPS, the JETRO English database, and the many ministry, agency, and local-government systems, Japanese tenders are scattered and largely Japanese-language. Hook indexes them, lets you search in plain English, and alerts you when relevant contracts appear.

- Relying on JETRO alone. It covers GPA notices only — much procurement sits below threshold or with non-covered entities, in Japanese.
- Skipping the Unified Qualification. Without it, you cannot enter central-government open competitive bidding.
- Underestimating the language barrier. The full specification and the bid itself are usually in Japanese, even for GPA-covered tenders.
- Misreading the grade band. Your A/B/C/D grade limits which contract sizes you can bid on — bidding outside your band wastes effort.
- Ignoring comprehensive evaluation. Many tenders score technical merit, not just lowest price — a thin proposal loses on points.
Common questions about Japanese procurement
Is there a single procurement portal for Japan?
Not quite. Japan publishes official tender notices in the Kanpo (官報), the government gazette, and runs electronic procurement mainly through GEPS (Government Electronic Procurement System, 電子調達システム) for central-government bodies. JETRO (the Japan External Trade Organization) maintains an English-language Government Procurement Database that aggregates WTO-GPA-covered notices specifically for foreign suppliers. But ministries, agencies, local governments (prefectures and municipalities), and independent administrative agencies also run their own systems, so coverage is spread across several channels.
Can foreign companies bid on Japanese government tenders?
Yes. Japan is a party to the WTO Government Procurement Agreement, so for covered entities and above the GPA thresholds, foreign suppliers have guaranteed non-discriminatory access. JETRO actively supports foreign participation and publishes covered notices in English. Below the GPA thresholds and outside covered entities, procurement follows domestic rules and is conducted in Japanese, where foreign access is possible but practically harder without local language capability and a local presence.
What is the Unified Qualification (全省庁統一資格)?
The Unified Qualification for Participating in Tenders (zenshōchō tōitsu shikaku) is a single supplier qualification accepted by all central-government ministries and agencies. Suppliers apply once, are graded (A/B/C/D based on factors like capital and turnover) per category — manufacturing, sales, services — and that grade determines which contract sizes they can bid on. Holding the Unified Qualification lets you bid across the whole of central government rather than re-qualifying with each ministry.
What are the main tender methods in Japan?
The three core methods are: open competitive bidding (一般競争入札, ippan kyōsō nyūsatsu), the default for GPA-covered procurement; selective/designated competitive bidding (指名競争入札, shimei kyōsō nyūsatsu), where the buyer invites pre-selected qualified suppliers; and discretionary/negotiated contracts (随意契約, zui-i keiyaku) for limited circumstances. For complex needs, comprehensive evaluation bidding (総合評価落札方式) scores technical merit alongside price rather than awarding purely on lowest bid.
What are the GPA thresholds for Japan?
Japan applies WTO-GPA thresholds expressed in Special Drawing Rights (SDR) and converted to yen for each two-year period. As a broad guide, central-government supplies and services sit around the low hundreds of thousands of SDR (roughly tens of millions of yen), with much higher thresholds for construction, and separate figures for sub-central entities and covered enterprises. Above the threshold, English notices appear in the JETRO database and open competitive bidding applies. Always verify the current yen figures, which are published periodically.
