Indexed identifiers in Japan, daily dashed = one of our discovery sweeps, not a wave of registrations 30 July 2026 → 20 September 2026

This counts identifiers present in our index. The index grows both when companies register and when our own discovery passes resolve identifiers that were already registered, so a step is not the same thing as a joiner count.

Peppol providers serving Japan

15 operators publish participants we can attribute to Japan. Ranked by the participants each one actually serves there — not by marketing reach, and not by where the company is registered.

7 further operators serve smaller numbers in Japan. The full provider directory ranks all of them.

The counts above are participants we can ATTRIBUTE to an operator from SMP publication, and they add up to 10,459. That is slightly more than the 10,368 identifiers the country facet holds for Japan, because the two are counted differently: the facet buckets an identifier by the country code inside the identifier itself, while attribution follows the seats each operator publishes, which resolve a country for some identifiers the facet cannot. Neither number is a subset of the other. Shares in the table are of the attributed total, so they are shares of what is measured, not estimates of the whole market.

FAQ

Peppol in Japan: common questions

How many companies use Peppol in Japan?

We index 10,368 Peppol participant identifiers registered in Japan, which is 0.1% of the whole network and puts the country at rank #18 of 122 indexed markets. That counts identifiers, not organisations: one company can hold several, for instance a VAT number and a company registration number. The count is rebuilt from the Peppol directory and every SMP we can resolve, and it moves both when companies register and when our own discovery passes resolve identifiers that were already there.

Which Peppol access points serve Japan?

15 providers have participants in Japan that we can attribute to them. The largest is TKC Corporation, with 5,497 attributed participants (52.6% of the attributed total). The table above lists the rest in order. Attribution is measured from SMP publication, not from what an operator claims, so a provider appears here only where we can actually see its participants.

Is Peppol down in Japan?

Peppol is a pan-European network, so it is not up or down per country. Japan's invoices travel over the same SML, SMPs and access points as everywhere else. What CAN be country-specific is the operator you use, so check that operator's status rather than the country: the live network verdict and every monitored host are on our status page.
