A Kobe trade in rayon and sundry goods turned, in November 1928, into a workshop of about thirty people assembling cameras from imported parts on the bank of the Mukogawa river. Over the next seventeen years those imported parts were replaced one by one, the Minolta name was fixed first to a product and then to the company, and a naval order accepted in the full knowledge that it would lose money brought with it an instruction to melt optical glass at Itami — a plant built for the war that would still be a competitive asset thirty years afterwards.
From a trade that could not command a price to products with a high degree of workmanship
Tajima Kazuo (田嶋一雄), who handled exports of rayon and sundry goods at the Kobe trading house Tajima Shoten, was dissatisfied with the very goods he dealt in. In November 1927 he sailed from Kobe as a member of the Japanese Goods Travelling Trade Mission (日本商品旅商団) sponsored by the Ministry of Commerce and Industry, and spent some six months touring the Near and Middle East and eastern Europe. Early the following year, meeting a customer again in Cairo, he was told that imitations closely resembling the cotton cloth he had himself opened up were flowing in cheaply by another route, leaving him no time to enjoy the advantage of having gone first. Tajima concluded then that there is no pleasure in going on for ever with goods whose price will not hold
, and that no business would stand unless it made products with a high degree of workmanship that other firms would find hard to copy.
That the object of the change should be cameras was settled by a visit, on the same journey, to the works of the Paris optical-armaments company SOM. Rangefinders were lined up there, mass-produced almost exclusively for the Japanese army, and he was told that the price passed at whatever the maker asked. The contrast with textiles, whose price would not hold, was great, and Tajima could not get the two characters for optics
out of his head. Soon after he returned home, Willy Heilemann, who was importing German photographic supplies in Kobe, called on him bringing Billy Neumann, an engineer who had worked at an optical-instrument company in Paris. When the two of them together urged him to manufacture cameras, Tajima saw that the rangefinders he had seen in Paris and the camera in front of him were joined at the single point of being optical instruments, and decided to take the proposal up.
On 11 November 1928 Tajima opened a sole proprietorship, Nichi-Doku Shashinki Shoten (日独写真機商店, the Japanese-German Camera Shop), on the bank of the Mukogawa at Naruo village, Muko district, Hyogo prefecture. The site ran to 300 tsubo, the wooden building — partly two-storeyed — to 130 tsubo of floor area, and the staff numbered about thirty including himself. His father refused to make it a new venture of Tajima Shoten, saying the trade was too far removed from ours to be anything but dangerous
, and went no further than handing over ¥5,000 from a matured life-insurance policy. The rest was met by borrowing from the head clerk who ran the family's lacquerware business, which at last brought the sum up to the ¥15,000 minimum required. In the Japan of that day the only large domestic maker of cameras was Konishiroku, and most of the market was held by imports from Germany and the rest of Europe and America. Just after the financial panic, an unknown workshop joined that market.
A decade of replacing imported parts one by one, and the fixing of the Minolta name
In March 1929, four months after the founding, the first machine, the Nifcalette, was completed. It was a bellows-type hand camera taking eight exposures on roll film, and both its lens and its shutter depended on imports. The price was ¥20 a camera, and from the third month output passed 100 units a month. But when trade turned downhill under the retrenchment policy, sales slowed, and Tajima once carried a hundred cameras to Tokyo to raise money and came home without selling one, refusing to cut the price. Working capital was got through again and again by borrowing from the family head clerk, and the total came to more than ¥50,000. In October 1930 resentment against the works manager and others led to a strike, and Tajima, yielding to Heilemann's forceful insistence, dismissed the whole workforce for a time.
In February 1931 the company launched the Nifcadox, which carried a shutter of its own manufacture; it sold well and the borrowings were repaid in full. On 1 July of the same year the sole proprietorship was reorganised as Molta Goshi Kaisha (モルタ合資会社), with its head office at Kitakyutaromachi, Higashi ward, Osaka. The works had more than seventy employees, but the head office was a small household of four, Tajima and his younger brother Tajima Toyojiro (田嶋豊次郎), who handled the accounts, among them. Then in November that year Heilemann, on whom the company had relied, gave notice that he was starting a business in camera parts and left; when the year turned, Neumann followed him, taking several workmen with him. Losing the pivot of its technique, Tajima resolved that from now on we shall do it with Japanese alone
, and in April 1932 organised production by setting up finishing, lathe, shutter and painting departments and a general affairs section. Morale within the company rose rather than fell, and a mood grew up of making shutters in-house and using domestic lenses as far as possible. The departure of the two Germans in fact hastened the replacement of imported parts by home-made ones.
In the middle of 1933 the name Minolta was given to a quick-shooting model whose lens and shutter sprang out at the press of a button. The name joined the initials of the English for Tajima's optical instruments, and carried over it also the sense of ripening rice field
(稔る田), after a precept of his mother. In January 1934 came the Minolta Vest, a rigid-bellows camera using Bakelite in place of the sheepskin that had grown hard to obtain, sold at ¥19.50; it earned the nickname Osaka Castle
and sold widely. In July 1936 the company acquired a site of about 600 tsubo at Amagasaki and set up the Nihon Kogaku Kikai Kenkyujo (日本光学機械研究所, the Japan Optical Machinery Research Institute), where the foreman Kitakaze Kumataro (北風熊太郎) and others were put to work on a twin-lens reflex. They slept and ate in one room while they developed it, succeeded for the first time in Japan, and at the end of 1937 the Minoltaflex went on sale. In the same year a lens works was built at Sakai. In September 1937, judging that a limited partnership could not go far enough in meeting a wartime economy, Tajima converted the firm into a joint-stock company and changed its name to Chiyoda Kogaku Seiko (千代田光学精工). Capital stood at ¥1.5m, and the three works together had grown to some 1,000 employees.
A naval order taken at a known loss, and an optical-glass works built to military order
In 1938, with materials for cameras growing hard to obtain, Tajima came to the conclusion that actively taking on military equipment in which our optical technique can be used is the one road by which we can also go on manufacturing cameras for civilian demand
. After calling two and three times at the Navy Technical Department (海軍艦政本部) in Tokyo, he obtained an approach about seven-power, fifty-millimetre prism binoculars. But when the specification was examined, the works' estimated cost was ¥200 a unit against a delivery price fixed at ¥139.75, which at the target of 1,000 units a month worked out at a loss of about ¥60,000 a month. Opinion at the works was overwhelmingly that the order should be declined, but Tajima argued that even if we lose money on binoculars the company as a whole can stay in the black
, and full production began at the Sakai works in November 1938.
On the heels of that order came a new process, the melting of optical glass. In January 1942 a notice arrived in the name of the head of the Navy Technical Department instructing the company to build a melting works for optical glass with all speed
. At that time private manufacture of optical glass was concentrated entirely in the Tokyo area — Nippon Kogaku on the navy side, Ohara Optical Glass on the army side and others — and there was none at all in the Kansai. The navy chose Chiyoda Kogaku as the place to disperse production to. Tajima found a suitable site at Itami in Hyogo prefecture and began building from the summer of that year, but shortages of materials and of skilled hands meant that nearly two years passed before it could run, and the furnace was not lit until June 1944. That year some 800 students were assigned to the works under labour mobilisation, and the total headcount at the end of the year reached 2,600.
The main products in the last stage of the war were optical weapons — telescopes, binoculars, gunsights, bearing compasses, aerial cameras — and 95 per cent of capacity was given over to military demand. In 1945 air raids destroyed the three works at Mukogawa, Komatsu and Amagasaki. Two months after the surrender, when each employee was left free to decide whether to stay, the workforce fell to about 400. That the company held out at all was because the Navy Technical Department paid over ¥5m as part of the money owed for deliveries up to the end of the war; the episode of making binoculars in the knowledge of a loss thus turned into working capital. Nihon Sangyoshi (日本産業史) records that the vast wartime investment in developing optical weapons trained engineers and became the foundation for raising the quality and performance of optical machinery
, while also saying that the counter-argument is nearer the truth: had that investment been directed at civilian uses from the start, larger results would have come sooner. The effect of military demand cannot be spoken of as an achievement. What remained to Minolta was the works at Itami where it could melt for itself the optical glass that other firms had no choice but to buy.
