Policy dossier: Japan
A one-country brief on Japan in European quantum technologies for policy makers, built only from data this portal already holds. Every figure names its source and reference date; ratios come with the counts they are made of. Nothing here is a ranking or a composite score: counts describe catalogue coverage, not national capability.

1. EU funding absorption
CORDIS covers Horizon 2020 and Horizon Europe quantum projects only: no other EU programme, no national or regional funding.
| Country or group | Participations | EU contribution | Population (year) | GDP, current prices (year) | Participations per million inhabitants | EU contribution per inhabitant | Participations per EUR billion of GDP | EU contribution per EUR billion of GDP |
|---|---|---|---|---|---|---|---|---|
| Japan (this dossier) | 30 | EUR 0 | - | - | - | - | - | - |
| EU27 average (pooled) | 3,714 | EUR 2.28 billion | 451,990,314 (2026) | EUR 18,883.19 billion (2025) | 8.2 | EUR 5.04 | 0.20 | EUR 120,646 |
Definitions: Participations by country; Net EU contribution to participants by country; Population, GDP and GERD (Eurostat); Participations per million inhabitants; Net EU contribution per inhabitant; Participations per EUR billion of GDP; Net EU contribution per EUR billion of GDP
No peer group: a population or GDP figure is missing for this country or for the candidate Member States.
Method: participations and EU contribution are CORDIS totals over all start years in the catalogue; population on 1 January and GDP at current prices are the latest single year Eurostat publishes for each country, so the ratios correct for size, not for time. Group averages are pooled: the group totals divided by the group population or GDP, never a mean of country ratios. The EU27 average pools 27 Member States. A dash means that a figure is not published or that the EU contribution is zero; "less than" marks a positive figure too small to show at this precision.

2. Specialisation by application pillar
| Pillar | Projects of Japan | Share of its projects | EU27 projects | EU27 share | Ratio (country share / EU27 share) |
|---|---|---|---|---|---|
| Quantum computing and simulation | fewer than 10 | not shown | 516 | 48.3% | not shown |
| Quantum communication | fewer than 10 | not shown | 116 | 10.9% | not shown |
| Quantum sensing and metrology | fewer than 10 | not shown | 189 | 17.7% | not shown |
| Enabling technologies and supply chain | fewer than 10 | not shown | 49 | 4.6% | not shown |
Definition: Specialisation by pillar against the EU27
Method: the share of the CORDIS quantum projects of the country in each pillar, divided by the same share for the EU27 (projects with at least one participant from a Member State). A ratio above 1 means the pillar weighs more in the projects of this country than in those of the EU27; it says nothing about size or quality. No count, share or ratio is shown from fewer than 10 projects of the country. Pillars follow the portal method (confirmed classification, else the taxonomy rules on the title, else a matched keyword suggestion); a project in several pillars counts in each, and fewer than 10 projects of this country are not placed in a pillar.

3. Collaboration: top partner countries
| Partner country | Shared projects |
|---|---|
| France | 10 |
| Germany | 10 |
| Italy | 9 |
| Netherlands | 7 |
| Spain | 7 |
| United Kingdom | 7 |
| Denmark | 6 |
| Switzerland | 5 |
| Czechia | 4 |
| Finland | 4 |
Definition: Top partner countries
A project is shared when organisations of both countries take part in it; this shows co-participation, not the strength of a relationship. Counts cover CORDIS quantum projects only (Horizon 2020 and Horizon Europe).

4. National programmes and public investment
The public investment registry has no national programme or financing record for this country (compiled 2026-10-27; not exhaustive).
National sources and cohesion funding on this portal
No national open-data source or national funder of this country is connected to the portal yet.
| Source | Publisher | Licence | Last read (UTC) | Published on this portal |
|---|---|---|---|---|
| Kohesio (EU cohesion policy projects) | European Commission, Directorate-General for Regional and Urban Policy (DG REGIO) | CC0 1.0 (Cohesion Open Data Platform, dataset 2014-2020 Kohesio projects) | 2026-10-28 | 0 projects located in this country |
Definition: Records of connected national sources
Counts of records published on this portal at the time of the dossier, with node access; open notices only for procurement sources. Cohesion projects (Kohesio, EU cohesion policy, managed by national and regional authorities) are located in the country by the source; they are not in CORDIS and not part of the absorption figures. The record at each source is authoritative.
5. Infrastructure
EuroQCI: no EuroQCI project located in this country is in the catalogue. Cross-border EuroQCI projects listed as EU-wide are not attributed to a country.
The infrastructure catalogue has no entry located in this country.
Source: the infrastructure catalogue of this portal, compiled 2026-10-27 from official programme, government and host pages; a referral list, not confirmed by the providers.
6. Post-quantum cryptography readiness
Not covered: the PQC guide records the national guidance status of the 27 EU Member States only.
7. Approved evidence from published reports
- approximately 0.4% in 2015 to 1.1% by 2023 Quantum's share of public R&D project funding in the OECD Fundstat database rose from about 0.4% in 2015 to 1.1% in 2023, after a peak of 1.2% in 2022. Reference period 2015-2023; 19 OECD countries and EU programmes in OECD Fundstat; Observation; checked 2026-10-22. OECD and European Patent Office, Mapping the global quantum ecosystem (December 2025). Printed page 23, PDF page 23, Executive summary, 6. R&D-focused public policies, Figure E11 and its notes.
Values as the publisher states them, each with its edition and page. Groups of countries are named in full; a figure about a group is not a figure about this country alone. Estimates of different publishers are never added up or averaged.

8. Gaps and caveats
- EU funding absorption: Eurostat publishes no population figure for this country, so no figure per million inhabitants is shown.
- EU funding absorption: Eurostat publishes no GDP figure for this country, so no figure per EUR billion of GDP is shown.
- EU funding absorption: No peer group could be formed: a population or GDP figure is missing for this country or for the candidate Member States.
- Specialisation: Every pillar has fewer than 10 projects of this country: no share or ratio is shown.
- National programmes: The public investment registry has no national programme or financing record for this country; the registry is not exhaustive.
- National programmes: No national open-data source or national funder of this country is connected to the portal.
- Infrastructure: The infrastructure catalogue has no entry located in this country.
- Infrastructure: The catalogue has no EuroQCI project located in this country; cross-border EuroQCI projects listed as EU-wide are not attributed to a country.
- PQC readiness: The PQC guide covers the 27 EU Member States only.
- Always: CORDIS covers Horizon 2020 and Horizon Europe quantum projects only, found by the word quantum in their title, acronym or topic; it is catalogue coverage, not a census. National budgets, private investment and other EU programmes are not in the absorption figures.
- Always: no league table or composite score is computed; a ratio is only as good as its counts, which are shown next to it.
