What's the deal? DensanDealroom has a profile for this one. Try Dealroom →, a Nagano-based IT company, has acquired 100% of Nihon Exa SystemDealroom has a profile for this one. Try Dealroom →, a Tokyo software developer, making it a wholly owned subsidiary. Densan bought the shares from Exa's two individual shareholders, completing the deal on September 7, 2026.
What do they do? Densan, founded in 1966, provides packaged and custom systems for local governments, private firms, and medical and welfare institutions. Exa, founded in 1990, has long worked as a development partner to large systems integrators across manufacturing, distribution, trading, and pharmaceuticals.
Why now? Densan wants to make industry a pillar of its business, tapping the manufacturing base in its region. It says securing skilled engineers is essential — and Exa brings deep experience with "mcframe," an ERP/SCM package for manufacturers that Densan also handles.
What's the endgame? Densan aims to combine Exa's technical skills with its own sales base to offer end-to-end service from development to maintenance. The added engineering resources should let the group take on mcframe projects it previously turned down for lack of staff.
The company also expects to bring formerly outsourced development in-house, lifting service capacity and profit margins. Densan said the deal will have a "minor" impact on its earnings for the year ending March 2027.
The signal: The acquisition fits Densan's 2026–2028 mid-term plan, which flags alliances as a route to widen its business scope. For a 60-year-old regional systems house, buying an established SI partner is a bid to move up the value chain in industrial software.
