Company history

Henmi Yoshichika had wanted to be a trading-company buyer. The recession after the oil shock left him instead at a software firm that, in practice, did little more than second engineers out to client sites in Nagoya and elsewhere; he quit after two years. What held him was the microcomputer. “You cannot service a jet alone, but you can service a Cessna” — mainframes belonged to large organizations, while microcomputer software was work a single person could own end to end. He went freelance at twenty-four, designing at home and travelling to customers to implement, and in March 1983 incorporated Henmi Engineering in his brother-in-law’s apartment in Yokohama with $8,422 (¥2m) of capital and two desks. In February 1984 it was renamed System Pro.

Japan’s software industry then ran on subcontracting to the mainframe vendors — NEC, Fujitsu, Hitachi — with small specialist teams forming around the edges. Embedded and communications work was plentiful, and orders arrived without any sales effort at all. That abundance forced the founding choice. Hiring aggressively would have grown the company but turned it back into the body shop Henmi had left, so he kept headcount at effectively two, worked with outside contractors, and declined about 70% of incoming orders in order to take only the jobs he wanted. He also pushed part of the contract earnings into products of his own: a failed arithmetic drill for schoolchildren, then in 1987 Jan Net, an online mahjong game played over telephone lines, where the host computer stood in for a missing player and kept the game alive when a line dropped. Making real-time play work over Meiji-era copper was the technical education that defined the firm.

By his early thirties Henmi conceded that the small-is-beautiful model had capped him: revenue was ¥35 million against a target of ¥100 million. He switched to growth, and by fiscal 1991 sales reached $1M (¥135m), more than fivefold in five years. In the 1990s the communications know-how from Jan Net moved into mobile: PHS software first, then handset software from 1996. Each generational change — 2G to 3G — required carriers and handset makers to rewrite terminal software wholesale, and System Pro took that rework again and again. The mobile-communications core technology accumulated in those years is the same base its automotive business would run on a quarter-century later.

System Pro listed on Nasdaq Japan in August 2002, nineteen years after founding. It was the inverse of the founder’s original posture: in exchange for explaining results to outside shareholders forever, the company bought a standing tap of capital with which to hire engineers. A second offering in 2004 raised roughly ten times the IPO, which is the clearest evidence that listing was not a one-off event but a funding mechanism. When Nasdaq Japan’s momentum faded, the company moved to deeper markets — TSE Second Section in November 2004, First Section in October 2005 — completing both steps inside a year.

The 2G-to-3G transition drove the numbers: sales rose from ¥2.46bn in FY2003 to ¥5.92bn in FY2006, ¥7.93bn in FY2007 and ¥9.60bn in FY2008. But the securities filings showed the cost of that growth. Every year, two or so customers each accounted for more than 10% of total sales — NEC at 13.2% and Vodafone at 11.7% in the year to October 2005, then KDDI Technology at 17.3%, and above all a Sharp-affiliated software house at 22.6%, 23.7% and 27.5% in successive periods. Roughly a quarter of revenue sat with one buyer. In a business where revenue grows by adding engineers, the pace of hiring was being set not by Systena but by that customer’s development plans.

In April 2010 the company absorbed Catena Corporation, a mid-sized enterprise systems integrator, after three years of raising its stake. The smaller firm swallowed the larger one, but reversal was not the point: the merger added Catena’s enterprise SI business, its financial-sector clients and its sales organization to System Pro’s embedded and communications engineering. The combined entity was briefly called Syspro Catena and, in July 2010, renamed Systena Corporation — a specialist shop rebranded as a full-line IT provider.

The effect on the numbers was immediate and structural. FY2010 sales, after the fiscal-year-ends were aligned, came in around ten times the prior short period, and in the year to March 2011 no customer accounted for as much as 10% of sales. The business was reorganized into six or seven segments — IT services, solution sales, solution design, framework design, cloud, consumer services and overseas — with solution sales the largest at about ¥15.1bn in FY2014 and solution design at ¥11.7bn. Enterprise SI from the Catena side and communications and embedded work from the System Pro side now stood as twin pillars.

One inheritance from the founder survived every reorganization. Henmi had promised shareholders a payout ratio — 30% from the IPO years, raised to 40% from the year to October 2006, when the dividend was $9 (¥1,000) per share against a 43.8% payout. Because the promise was expressed as a ratio rather than an absolute amount, it survived a business whose profit scale moved by an order of magnitude, and it underwrote what became twenty consecutive years without a dividend cut. It also fixed a ceiling on retained cash, which is the constraint the company still works within.

In March 2016 Henmi moved up to chairman and Miura Kenji became president. His strategy was reallocation rather than expansion: instead of running six roughly equal segments, he shifted people and money toward whichever had the most room to grow, on a three-to-five-year investment horizon. Sales climbed from ¥42.7bn in FY2015 to ¥59.7bn in FY2018 and ¥64.6bn in FY2019, with a 12.6% operating margin — high for an industry priced by the engineer-month. The pandemic year barely dented it, at ¥60.9bn, and recovery carried sales to ¥74.5bn by FY2022.

The chosen field was the automobile. Miura argued that almost every part of CASE — connected, autonomous, shared, electric — resolves into software, and that the core technology Systena had built by rewriting handset software through every mobile generation transfers directly to vehicles. That let it deal directly with automakers and Tier 1 suppliers rather than sitting under a systems integrator, and few IT firms can cover all four CASE domains as one stop. FY2024 (to March 2025) set records: sales of ¥83.6bn, operating profit of ¥12.1bn on a 14.4% margin, and net profit of ¥8.5bn. Within it, the next-generation mobility business ran at a 35% operating margin in the third quarter of 2025, with profit up more than 200% year on year.

The tension the company carries is visible in that result. Having escaped dependence on one customer in 2010, Systena has deliberately concentrated again — this time on a technology theme rather than a buyer — while the founder’s 40% payout promise continues to send most of the profit out the door. Miura has answered by treating cash allocation as a portfolio: dividends, investment in staff, share buybacks and M&A studied in parallel. Whether the mobility business can keep compounding, and whether the older IT, cloud and consumer segments can be revived alongside it, is the question the payout ratio makes sharp.
