Founding
In November 1941 the brothers Yamanaka Shoichi and Yamanaka Shigeru, who until then had run a paper-manufacturing business, founded Toyo Optical Glass Works at Hoya-machi in the Kitatama district of Tokyo prefecture. Producing at home the optical glass that could no longer be imported from Germany was a national priority, and Shoichi slept in front of the melting furnace, working through crucible shapes and melting temperatures until he reached Hoya BK7 in March 1943 and the works was designated a Navy-controlled plant. But the end of the war in 1945 wiped out military demand, and revenue fell to almost nothing while the company still carried a workforce of some 100. It rebuilt afterwards by exporting crystal tableware to North America, where about nine-tenths of sales came to rest, and then the single exchange rate of ¥360 to the dollar in 1949 destroyed the economics of that trade. In 1950 it dismissed most of its 550 employees, having lived through two collapses of entirely different character within nine years of its founding.
The Decision
HOYA turned from a company that lined businesses up into one that swapped them according to the return on its capital. Eyeglass lenses in 1962, mask substrates for semiconductors in 1974 and glass discs for hard-disk drives in 1991 had little to do with one another, and the result was the strain of charging mature and growing businesses the same cost of assets. In April 1997 it cut the head office back to strategic planning, finance, legal affairs and general administration alone, making the growth businesses in-house companies and the mature businesses subsidiaries. It set out a plan to take the parent company from 2,020 employees to 50, and halved the board from sixteen directors to eight. In 1998 it introduced SVA to measure, business by business, the value added above the cost of capital, and in June 2003 it converted to a company with statutory committees on which outside directors held the majority. A mechanism for deciding whether a business lived or died by its return rather than by sentiment is what made the acquisitions and disposals that followed so quick.
Today
More than half of the profit comes from a business that is only a third or so of revenue. Of revenue of $6.0B (¥948bn) in the year to March 2026, Life Care accounted for $3.7B (¥591bn) and Information Technology for $2.2B (¥355bn), while segment profit ran the other way round at $818.8M (¥130bn) against $1.2B (¥192bn). The 54.2 per cent margin of Information Technology is more than double the 21.9 per cent of Life Care. The revenue side was thickened by acquisitions from 2012 onwards: after taking over Seiko Epson's eyeglass-lens development and manufacturing operation, the company bought a US maker for $437.3M (¥48bn) and secured the second-largest position in eyeglass lenses in the world. The profit side rests on the semiconductor mask blanks begun in 1974 and on glass substrates for hard-disk drives. Ikeda Eiichiro, who in March 2022 succeeded Suzuki Hiroshi after his twenty-one years as chief executive, has said that rotating the businesses is the chief executive's greatest duty.
Competition
The path of letting go of cameras and staying in medicine, Olympus grew for itself and HOYA bought. Olympus set up a Third Business Division in 1969 and raised the endoscope into a product of its own, and in 2020 it transferred its camera business away. HOYA acquired Pentax in 2007 for $804.1M (¥95bn), kept the endoscopes it was after, and in October 2011 sold the loss-making digital camera business to Ricoh; in the year to March 2009 it booked an impairment loss of $293M (¥27bn) on Pentax-related assets. In eyeglass lenses too it stacked up acquisitions of small and mid-sized makers until it stood second in the world. Replacing the time it would have taken to grow those businesses with acquisition prices and impairments is what turned a maker of optical glass into a company that earns from two things, medicine and mask blanks.

Founding Story

1941–1956Two collapses in the first decade: military glass, then crystal exports

HOYA's first fifteen years handed it the same lesson twice. The company was built to melt a glass Japan could no longer import, and on both occasions the demand it had organised itself around — the Navy's first, then North America's appetite for crystal chandeliers — disappeared on a date set by somebody else, leaving a payroll it could not carry.

An outsider's obsession with melting BK7 optical glass

HOYA's starting point is November 1941, when the brothers Yamanaka Shoichi (山中正一) and Yamanaka Shigeru (山中茂) founded Toyo Optical Glass Works at Hoya-machi in the Kitatama district of Tokyo prefecture[1]. The brothers had until then run a paper-manufacturing business, so this was an entry from an industry far removed from the making of optical glass; the immediate trigger for the venture was the national requirement, under the Pacific War, to produce military optical glass at home. Japan's optical industry at the time rested on a fragile structure dependent on imports from Germany, and with wartime supply lines severed the country was forced to improvise a domestic production base at speed. Yamanaka Shoichi himself laid a straw mat in front of the melting furnace and slept beside it, working through combinations of crucible shape and melting temperature by day and by night in a dogged, self-directed development of a glass-melting method.

After roughly two years of trial and error he completed a new crucible in March 1943 and reached the melting of the optical glass Hoya BK7. The quality was recognised by the Navy, the works was designated a Navy-controlled plant, and the company secured a stable outlet for military supply — yet this achievement carried within it the precariousness of its own starting point. With the end of the war in 1945 military demand vanished, and the company was struck by a situation in which revenue fell to almost nothing while it still carried a workforce of some 100 people. Losing the basis of its survival barely four years after founding etched, in both the management and the founding family, a memory of how dangerous concentration is. Experiencing at first hand, at that early stage, the seed of ruin contained inside a prosperous line of business became the source of the diversifying instinct that followed.

The exchange-rate collapse that taught concentration risk

After the war HOYA shifted the axis of its business from military optics to the manufacture of crystal glass tableware[2] and, starting from sales to US military personnel, moved in earnest into the North American market. This was precisely the period when the communisation of Czechoslovakia had cut off the supply of high-end chandeliers from Europe, leaving a vacuum in North American demand for crystal tableware. HOYA moved nimbly into that gap and grew, and within a short time a structure formed in which about 90 per cent of sales depended on North American exports centred on chandeliers. That dependence had the same shape as the earlier 100-per-cent reliance on military orders: only the industry and the geography of the customer had changed, and the concentration risk had not been resolved at all. Even after the collapse of military demand, a dependent earnings structure had repeated itself.

In 1949 a single exchange rate of ¥360 to the dollar was established. Revalued from the prevailing rate of around ¥600 to the dollar, the economics of exporting collapsed overnight under roughly 40 per cent of upward pressure on the yen. In 1950 HOYA was forced to choose to dismiss most of its 550 employees and restart with a body of fewer than 100, and so within nine years of its founding it lived through two consecutive crises of entirely different character — the disappearance of military demand and the collapse of crystal exports. Those two experiences worked as the origin of the management culture that followed, etching into the bedrock of the company both a wariness of dependence on a single customer, a single market or a single product, and the idea of holding several niche markets at once so that the risk of the whole is spread.

1957–1989Suzuki Tetsuo and the high-margin model of niche oligopoly

Under Suzuki Tetsuo, who led the company for most of three decades from 1957, HOYA turned that hard-bought wariness into a method: hold more than half of several small markets nobody else could easily enter, and keep production deliberately short of what the sales force could sell. Revenue rose from $1.7M (¥609m) in 1959 to $263.8M (¥60bn) in 1980, and by the close of the era the company held the leading share in eyeglass lenses, crystal tableware, optical lenses and semiconductor mask blanks at the same time.

The five-year plan and a direct sales system built for the cycle

In 1957, following a sudden death in the founding family, Suzuki Tetsuo (鈴木哲夫), then 32 years old and the company's chief engineer, became president[3]. In 1960 he drew up the first five-year plan since the founding, placing three pillars at its core: the merger of three affiliated companies, the introduction of a divisional structure, and the building of a direct sales network[4]. Suzuki preached repeatedly a management philosophy holding that a product not accepted in the domestic market rarely succeeds abroad, and set the establishment of competitive advantage at home as the starting point of management. The heart of the direct-sales system lay in the design of operations itself: taking selling power as 100, he deliberately held production capacity to 85 and filled the shortfall through outside contractors, adopting this balance between production and sales as a mechanism of the company's own. That deliberate asymmetry between selling power and production power was itself the source of HOYA's particular resilience to the cycle.

With this mechanism HOYA could keep its own plants running at full capacity even through downturns, acquiring a resilience to the cycle that avoided the vicious circle of excess stock followed by discounting. In 1967 advance investment in the eyeglass business produced a loss, and under pressure from the main bank Suzuki stepped down from the presidency for a time[5]; he then bought up shares and returned as president in 1970. The story of that resignation and return has been handed down as an illustration of the strength of Suzuki's personal will as a manager, and it became the reason HOYA continued to be run under a consistent management philosophy even after the founding family had withdrawn from the business. Having once submitted to bank-led governance also laid the ground for the later emphasis on ROE and on capital efficiency.

Market share defined as an asset

After his return Suzuki Tetsuo defined market share as an asset and set the whole company a numerical target of more than 50 per cent share in its core products. The design was that high share lowers the cost per unit of product and generates a cycle that widens the gap in investment capacity against competitors. In 1974 the company began manufacturing mask substrates for semiconductors[6] and, starting from an order from IBM, built an integrated production system running from the glass substrate through to the chrome mask, sowing the seed of a long-term earnings base in the information and communications business. Even as the domestic economic environment changed, Suzuki's share strategy was maintained. Placing an early marker in semiconductor mask blanks — a niche with few customers and high barriers to entry — became a strength in later years.

By 1987 HOYA held the top share in several niche markets at once: 36 per cent in eyeglass lenses, 65 per cent in crystal tableware, 60 per cent in optical lenses and 75 per cent worldwide in mask blanks. Rather than chasing vast general markets, this strategy designed the company as a collection of niche oligopolies, taking a dominant position in small markets with high technical barriers to entry, and it showed in an operating margin of 12.5 per cent for the year ended March 1990. A structure holding several small near-monopolies in parallel made it possible to spread concentration risk and earn high returns at the same time, and the management culture etched in during the founding years took shape as a financial structure. The lesson learned from the disappearance of military demand and the collapse of crystal exports appeared, thirty years on, in inverted form.
