Jasmy Moves Beyond Government Compatibility: Nagano Prefecture Is Now Using Jasmy Infrastructure

For some time, Jasmy’s relationship with the Japanese government has been difficult to define. The company has developed technology compatible with Japan’s My Number Card and JPKI digital identity infrastructure, and the Digital Agency has published Jasmy’s Personal Data Locker as a recognised use case.

But there is now something much more concrete.

Nagano Prefecture has an operational public-sector project using digital infrastructure provided by Jasmy.

The Nagano Prefecture project

Nagano Prefecture is operating the “Wagamachi Carbon Credit NAGANO Project”, a regional initiative designed to digitise and circulate carbon credits generated within Nagano.

The project formally began operating on 5 June 2025.

The participating organisations include:

• Nagano Prefecture

• Tokio Marine & Nichido Fire Insurance

• TOSYS

• Nippon Travel Agency

• Jasmy Co., Ltd.

Importantly, Jasmy is not simply listed as a promotional partner.

According to Jasmy’s own project announcement, the company provides the digital infrastructure and system platform supporting the project. This means Jasmy technology is being used in a real government-backed service rather than merely being demonstrated as something that could eventually be used by government.

What does the system do?

The project is intended to create a digital mechanism through which carbon credits generated within Nagano can circulate between businesses and residents.

In simple terms:

Why this matters

Jasmy has stated that its proprietary blockchain technology is used within the platform.

That makes this particularly noteworthy because it demonstrates an operational use of Jasmy technology within a project led by a Japanese prefectural government.

Until now, much of the discussion around Jasmy and government has centred on technical compatibility.

For example, Jasmy’s Personal Data Locker has been developed to support authentication through Japan’s My Number Card and JPKI system.

Panasonic Advanced Technology and Jasmy have also developed My Number authentication functionality and have stated that they intend to promote Jasmy-based applications to local governments, businesses and educational institutions.

Those developments are important, but they do not by themselves demonstrate government adoption. Now, however, we have real activity in Nagano!

Nagano is different.

We now have:

Together, the checklist (left) changes the current narrative from “technology that could potentially be used by government” to:

“technology already being used within a Japanese government-led project.”

Is Nagano using the Personal Data Locker?

This is where the distinction becomes important.

There is currently no clear evidence that the Nagano carbon-credit platform specifically uses

Jasmy Personal Data Locker (PDL).

The project confirms the use of Jasmy infrastructure and blockchain technology, but that does not automatically mean PDL forms part of the architecture.

So we should not yet say:

“Nagano Prefecture has deployed Jasmy PDL.”

What we can say is:

Nagano Prefecture is operating a project in which Jasmy provides blockchain-based digital infrastructure.

That is still significant. In fact, it is just the beginning of a massive move into the Japanese government's infrastructure. If the Nagano platform proves to operate through JasmyChain, the economic relationship becomes:

That would represent a direct economic link between a Japanese public-sector application and demand for the JASMY token.

But that connection has not yet been demonstrated.

The bigger picture is becoming clearer

Nagano becomes particularly interesting when viewed alongside Jasmy’s other developments.

Jasmy and Panasonic Advanced Technology have developed:

• My Number Card authentication

• JPKI identity verification

• Personal Data Locker

• IoT data processing

• developer SDKs

• Jasmy-based application frameworks

Meanwhile, Japan’s Digital Agency has formally presented Jasmy PDL and JPKI functionality within its My Number Card information for government and municipal use.

And now we know Jasmy is already supplying infrastructure to an operational Nagano Prefecture initiative.

The emerging progression therefore looks like this:

The first several stages are now backed by tangible evidence.

The final stages remain the ones investors should watch most closely.

What would be the next major breakthrough?

The next announcement I would regard as genuinely significant would be one of the following:

• A named municipality deploys Jasmy PDL for residents.

• A municipal service uses My Number/JPKI through Jasmy.

• Jasmy publishes actual resident or transaction numbers.

• Nagano or another government project is confirmed to operate on JasmyChain.

Or, most importantly:

A government-linked application is confirmed to generate JASMY gas usage.

That would connect government adoption not merely to Jasmy’s corporate technology, but directly to the economics of the JASMY token.

Bottom line

The Nagano project changes one important part of the Jasmy story.

It is no longer accurate to say Jasmy is simply trying to enter Japan’s government market.

There is now evidence of Jasmy infrastructure operating within a named Japanese prefectural government project. The next few announcements will be triggering.
