12 and 12 researched events on one shared scale. Horseman 1933–present, Yashica 1949–present.
The axis stretches where either maker has research and collapses where neither does, so a year sits opposite the same year on both. Event counts differ because research depth differs, not because one company did less.
Komamura Brothers began business in Kyoto, establishing the enterprise from which the later Komamura photographic company emerged. The date marks the commercial origin, not yet the formal postwar company or the Horseman camera brand, so those later milestones remain separate in the chronology.

Komamura identifies 1947 as the establishment of the postwar company and the beginning of film-development operations in northern Japan. This legal and operational milestone followed the 1933 business origin and immediately preceded the company's first documented police-camera project.

The wooden PC-101 identification camera was developed for the National Police Agency in 1948. In 1950 Komamura announced the Horseman 102 for police identification work, giving the Horseman name a practical foundation in controlled, repeatable evidentiary photography.

Yoshimasa Ushiyama's Lake Suwa workshop began with electric-clock components, then entered camera manufacture through the Pigeonflex and early Yashimaflex/Yashicaflex twin-lens reflexes. The move joined precision mechanics to a fast-growing Japanese export industry and created the product name that soon became the company name.
Yashicaflex, Yashica A, C, D, LM, 635, Mat and related models built a broad medium-format range. The cameras evolved through crank winding, meters, 127 and 120/220 formats, and changing Yashimar, Yashikor, Lumaxar and Yashinon lens packages while retaining the familiar waist-level reflex form.
A United States sales organization, movie cameras and the first Yashica 35 rangefinder widened the business beyond TLRs. In September 1958 the legal maker became Yashica Co., Ltd.; period cameras show the change from Yashima to Yashica markings more reliably than the simplified chronology in later promotional literature.

Komamura completed the Horseman 104 as an identification camera for the police. The model linked the early public-service cameras to the compact professional system that soon appeared under Topcon Horseman branding, combining Komamura direction with Tokyo Kogaku participation.

Yashica acquired Nicca's 35mm rangefinder operation, marketed the YE and YF, and absorbed the subsidiary over a longer interval than many summaries imply. Nicca experience contributed to Yashica's move toward interchangeable-lens cameras, although sources differ on the acquisition month and final legal absorption date.

The Pentamatic introduced Yashica's proprietary-bayonet 35mm SLR system, but its short production life was followed by the Penta J and J series using the widely shared M42 screw mount. Yashinon lenses could now travel across makers' bodies, and Yashica gained a more practical platform for its growing SLR range.

The 960, 760, 970, 980, and 985 developed the compact 6x9 press and technical-camera idea through several generations. Official service records preserve these distinct names alongside Super Topcor optics, while surviving manuals and systems show the importance of backs, cams, and rangefinder coupling.

The Electro 35 family turned electronic shutter timing and aperture-priority exposure into a simple rangefinder experience. Successive G, GS, GT, GSN, GTN, CC and MC versions made the concept one of Yashica's defining products, even though the often-quoted lifetime production total is not supported by a surviving factory ledger.
Tomioka Optical, already a Yashica lens supplier, came under Yashica capital in 1968. It produced SLR and other lenses, joined Kyocera with Yashica in 1983 and became Kyocera Optec in 1991, preserving an optical-manufacturing line that outlasted Yashica-branded camera production.

The VH and rangefinder-equipped VH-R carried the compact roll-film technical-camera concept into a mature system. Movements, interchangeable backs, ground-glass focusing, and model-specific rangefinder provisions made the cameras unusually versatile, but also created compatibility boundaries collectors must respect.

Yashica's cooperation with Carl Zeiss produced the Contax RTS and the shared Contax/Yashica bayonet. Zeiss supplied premium optical designs, while Yashica offered FX and FR bodies plus Yashica-branded DSB and ML lenses, creating an interoperable 35mm system without collapsing the partners' distinct design attributions.

The FX-1, FX-2, FR, FR I and FR II developed the consumer side of the shared mount, while the mechanically governed FX-3 became a long-lived entry body. Yashica ML lenses ranged from fisheye and fast normals to macro, mirror and zoom designs, sharing the bayonet and accessories with many Contax bodies.

Horseman 45FA, 45HD, and Woodman 45 brought folding-field portability to 4x5 photography. The 45FA and 45HD shared an 80 mm board concept but differed in rear movements, extension, focusing equipment, and front-rise control, so they represent distinct working bodies rather than trim variations.

The LS, LE, LX, and LX-C optical-bench cameras extended Horseman into modular studio work, with documented 4x5, 5x7, and 8x10 configurations. Their rail, bellows, standards, and interchangeable rear frames made format and movement capacity central parts of the system design.

Yashica Co., Ltd. merged into Kyocera in October 1983. Yashica continued as a consumer camera brand beside premium Contax products, with overseas manufacturing, autofocus SLRs, compact cameras, Samurai half-frame models and specialist Dental-Eye bodies extending the catalog into the digital transition.

SW612 and SW617 cameras turned 6x12 and 6x17 roll-film panoramas into purpose-built professional systems. Later Professional, SWP, SW612D, and SWD-II Pro variants brought interchangeable mounts, digital backs, and shift movements into the same wide-angle design tradition.

DigiWide, DigiFlex, LD, VCC Pro, ISS-G3, TS-Pro, and Axella products translated view-camera geometry into digital workflows. Rather than treating a sensor as a fixed endpoint, Horseman used interchangeable mounts, bellows, rails, and standards to keep perspective and focus control available.

Kyocera reported that intense digital-camera competition and inadequate cost reductions forced a major downsizing of its optical equipment group. Overseas sales companies closed, domestic camera operations contracted and the Yashica/Contax camera-making era ended, although Kyocera's optical-components business continued.

The Yashica badge entered a new Hong Kong-based trademark chapter and now appears on products promoted through a current YASHICA business. Separately, the Tomioka-derived Kyocera Optec operation continued industrial optical work and became Kyocera's Optical Components Division, so brand revival and manufacturing continuity are distinct stories.

Komamura transferred its photographic and broadcasting-equipment operations to Kenko Professional Imaging. Komamura continued separately in advanced imaging, while Kenko became steward of Horseman products, documentation, service information, and the professional-camera heritage.

Kenko Professional Imaging opened the Horseman Museum in Nakano in 2016 with cameras and accessories representing the brand's history, alongside then-current Axella and VCC Pro equipment. Current documentation preserves the system even though many historical bodies and lenses are no longer repairable.
