Preserving the "Cloud-Compatible Option" for Critical Business Communications in Japan

Our company supports April Dream, which aims to make April 1st a day for announcing dreams. This press release is the dream of "E-Post Inc."

Transforming email from an "old tool" into one of the "next regional communication infrastructures."

E-Post Inc. (Headquarters: Shinjuku-ku, Tokyo; Representative: Kazuya Imanishi; Abbreviation: E-Post) aims to create a society by 2040 where the option of "coexisting with the cloud" naturally remains for critical business communications in Japan.

And another dream is to nurture email not to end as an "old tool," but to become one of the "next regional communication infrastructures."

Our company was established in July 2000. For over 20 years, we have supported business communications for local governments and corporations through products such as E-Post Mail Server, E-Post SMTP Server, E-Post Secure Handler, and E-Post LGWAN Option.

Since its establishment in 2000, E-Post has supported business communications for local governments and corporations for over 20 years.

Local governments, corporations, educational institutions, medical and welfare sites, and local communities. In these "sites that cannot stop," we believe that not only convenience but also continuity and reliable management are important. As one of the foundations for this, we want to re-examine email. Email still has the advantages of being able to connect with many people, leaving records, and being easy to use across organizations, making it a good foundation for business communication.

On the other hand, in recent years, with the spread of convenient cloud services, there have been gradually more situations where it is difficult to have other options. We feel it is important to consider multiple forms of communication infrastructure to prepare for outages, communication disruptions, or specification changes.

We want to preserve "options," not just nostalgia

Cloud services have significant advantages, such as quick start-up and ease of use regardless of location.

However, for critical business communications, an infrastructure that can be held by one's own organization is sometimes more suitable.

For example,

・ Want to decide operational policies based on organizational judgment

・ Want to use within a closed network or with unique rules

・ Want to maintain communication infrastructure even during external outages

・ Want to maintain records and control independently over a long period

・ Want the IT department to manage it as part of their responsibility

For such sites, we want to preserve the option of communication infrastructure that can be held by one's own organization for the future.

Our flagship product, E-Post Mail Server, is a Japanese-made email server for domestic use, designed for on-premise operation. As of March 2026, it has been adopted by over 4,000 units nationwide and by approximately 300 government ministries, local governments, and general corporations. We aim to quietly continue supporting options that tend to be lost through this progress.

We want to nurture email as one of the "next regional communication infrastructures"

We want to nurture email not just as an old communication method, but as one of the foundations that will support future business and regional communication.

This is not just about sending and receiving.

・ Reliably deliver necessary information to necessary recipients.

・ Track who sent what and when.

・ Can be used for communication outside the organization.

・ Can be continued smoothly while leveraging existing operations and assets.

・ And can be treated by IT departments as a "foundation to protect."

We believe that email, with these characteristics, is a system that should be re-evaluated.

In the future, we envision a world where, starting with E-Post Mail Server and combining it with E-Post SMTP Server, E-Post Secure Handler, E-Post LGWAN Option, etc., we can smoothly expand into notifications, light chat-like interactions, information sharing, log preservation, and closed-network operations. The idea is not "email or something else," but "starting with email, expand necessary collaborations."

On this extension, we believe there is also the possibility of a mechanism that supports information in smaller, more localized settings. We are currently conducting concrete verification and prototyping for such an approach.

Towards a society where IT departments can have "foundations worth protecting"

As business systems increase and demands from the field diversify, the role of IT departments is becoming increasingly important. However, they are often busy with daily tasks, making it difficult to allocate sufficient time for infrastructure development. We believe that email infrastructure should be a "foundation worth protecting" that supports the continuity and trust of the organization.

Furthermore, the ability for an organization to easily grasp the location and management authority of important business data and communication logs will become increasingly important from the perspective of so-called data sovereignty.

・ Easy to introduce.

・ Can be operated continuously.

・ Easy to grasp the situation even during troubles.

・ Necessary controls and management remain in their hands.

・ Easy to grasp the location and management authority of important business data and communication logs.

Therefore, our company has developed product groups such as E-Post Mail Server, E-Post SMTP Server, E-Post Secure Handler, and E-Post LGWAN Option, making it easy to choose a configuration that suits each site without difficulty.

The future E-Post aims for

E-Post Inc.'s dream is to continue preserving the "cloud-compatible option" for critical business communications in Japan.

And another dream is to nurture email not to end as an "old tool," but to become one of the "next regional communication infrastructures."

Preserving and protecting the on-premise option, towards the next "Ark Project."

Not just convenience, but also continuity. Not just speed, but also manageability. Not just modernity, but also continuity and fault tolerance.

We believe that communication infrastructure with such values will continue to be gently needed in Japan in the future.

Leveraging our over 20 years of expertise in email infrastructure, we will first prioritize being realistically useful to local governments, corporations, and IT departments, and beyond that, we will also address communication methods closer to local communities.

The "Ark Project" connecting preparedness

As one such initiative, our company is advancing the concept and verification of a palm-sized autonomous regional disaster communication system, envisioned for securing communication in evacuation centers.

During large-scale disasters, regions can be cut off from information due to base station outages. While satellite internet services are effective for external communication, we believe that other measures are needed for detailed information sharing within evacuation centers and for supporting immediate operations.

We are recruiting companies, local governments, and field personnel to verify the "Ark Project."

Our envisioned E-Post TinyBox (tentative name) is an autonomous server that can operate even without internet access. Even if the external network is cut off, it can continue encrypted email and chat communication within a local network, aiming to serve as a coordinator to support smooth operations while minimizing information disparities within the "closed society" of an evacuation center. By linking multiple units, it is envisioned to flexibly expand the communication area even in large evacuation centers or buildings with many obstacles. Furthermore, starting from E-Post's email infrastructure, we envision a form that can gradually expand to more intuitive chat formats as needed.

Potential applications include information sharing via bulletin board functions in evacuation center management, privacy-conscious staff communication in medical and welfare settings, and daily/emergency communication in places with limited communication environments such as construction sites and mountainous areas.

This is not something that our company can complete alone; we want to gradually bring it to fruition together with local governments, sales partners, and companies in the communication, hardware, and disaster prevention fields.

Currently, as the "Ark Project," we are widely seeking partners who resonate with this dream and are willing to cooperate in its realization.

As an April Dream. And as an option that will truly be needed by society someday. E-Post Inc. will continue to consider the future of business communications in Japan in a grounded manner.
