The Shunrai Service from BIPROGY Inc - mainframe modernization as a managed bridge

The Shunrai Service from BIPROGY Inc hits you first with a quiet detail: a project manager sliding green and red sticky notes across a kanban board, mapping every legacy COBOL job before cut-over. Behind that calm gesture sits a heavy promise - mainframe without the migraine.

What the Shunrai Service is

BIPROGY launched the Shunrai Service as a managed modernization offering for customers that still run mission-critical workloads on its Unisys-derived mainframes. The bundle covers assessment, migration design, implementation and steady-state operations as a long-term service contract.

In practical terms, Shunrai wraps existing host applications with APIs, moves selected workloads toward open systems and clouds, and standardizes monitoring and incident handling under one operations team. According to the company, the approach targets Japanese banks, insurers and public bodies that cannot risk long outages.

How BIPROGY positions it

In BIPROGY's medium-term management plan, CEO Jun Tanaka points to mainframe modernization as a core pillar to grow recurring service revenue. Shunrai is positioned as a flagship template for that strategy, combining consulting, integration and infrastructure management into one package.

The company stresses that many long-standing System i and COBOL environments in Japan face staff shortages as veteran engineers retire. Shunrai aims to lower that human-resource risk by shifting responsibility for operations, documentation and knowledge capture into BIPROGY's managed service teams.

What customers actually get

On the ground, a Shunrai engagement starts with a discovery project. Engineers sit with client operations teams, trace night batch windows and identify interfaces that cannot break. That mapping flows into a phased modernization roadmap, typically spanning several years.

Instead of forcing a big-bang migration, BIPROGY describes Shunrai as a bridge that keeps core systems running while peeling off adjacent workloads. For example, customer data queries or reporting modules might move first to open platforms, while settlement logic remains on the host until later phases.

Tools, automation and operations

Shunrai leans on BIPROGY's own automation and monitoring tools, many developed for its outsourcing data centers. Log collection, job scheduling and alerting are standardized, which cuts down on the custom scripts that often hide in older mainframe environments.

Operations shift to a defined service-level structure, with response and resolution times agreed in advance. For a risk officer at a regional bank, that means fewer late-night calls to retired COBOL freelancers and more predictable support from a staffed operations center.

Risks and trade-offs

No modernization program is painless. Shunrai projects still require customers to document decades-old business rules, often without original engineers on hand. That makes workshops and reverse engineering sessions demanding, time-consuming work.

There is also the dependency question. Handing host operations and migration strategy to BIPROGY concentrates risk with one vendor. For some CIOs, the comfort of clear accountability outweighs that concern; others insist on keeping parts of operations in-house.

Where it sits in BIPROGY's portfolio

Shunrai does not stand alone. BIPROGY bundles it with its data-center outsourcing, cloud integration and security services as part of its broader "Business-IT linking" story in investor presentations. That portfolio mix aims to stabilize revenue as one-off hardware sales decline.

Compared with a pure consulting engagement, Shunrai's managed-operations component is designed to generate recurring fees over many years. That model aligns BIPROGY more closely with global IT service majors, but within the specific regulatory and cultural context of Japanese enterprise IT.

Context for investors and the share

All told, the Shunrai Service shows how BIPROGY is trying to turn a legacy mainframe base into a steady service business, rather than simply winding systems down. For investors, the BIPROGY Inc share price trades primarily on the Tokyo Stock Exchange under ISIN JP3834800006, with service growth a key narrative point.
