Tamura Manufacturing Co., Ltd.

Tamura Radio Shop established in Shinjuku, Tokyo.

Initially engaged in importing, selling, and repairing radios, but received orders for electric phonographs from Polydor, a record manufacturing company. Simultaneously started selling electric phonographs under their own brand.

Developed their own low-frequency transformer P72 model that significantly improved the sound quality of electric phonographs.

Developed a moving coil type microphone. Delivered to Asakusa International Theater and used at broadcasting stations across the country.

Aiming to shed the image of a local radio shop and become a manufacturer handling world-class products, established Tamura Manufacturing Co., Ltd.

Established Tamura Manufacturing Kashiwagi Laboratory. Developed communication devices and relay lines, laying the foundation for their communication equipment-related business.

The Oizumi factory was completed in Higashi-Oizumi, Nerima Ward. Most of the operations were transferred.

With the launch of Japan's first transistor radio, compact transformers were adopted. Along with an unprecedented hit, the company fully entered mass production of consumer parts.

Developed Japan's first fully non-corrosive soldering adhesive 'Solder Light' flux. Established an in-house chemistry research laboratory.

Listed shares on the Second Section of the Tokyo Stock Exchange.

Television rapidly spread into households. Developed the company's first model of audio equalizer for broadcasting equipment.

Entered the low-power radio equipment business. At the 1964 Tokyo Olympics, wireless microphones were installed at each venue and used for recording the official documentary film.

With the transition from vacuum tubes to transistors, printed circuit boards rapidly proliferated. Developed the company's first automatic soldering machine. Since then, it has supported the era of mass production of home appliances.

Established Taiwan Tamura Electronics as the first overseas production base. The goal was to secure labor and reduce costs in response to increased orders from the United States.

Leveraging a track record of high-reliability transformers, began developing transformers and coils for Japan's first operational satellite, the ionospheric observation satellite ISS (Ume), and the test satellite ETS-I (Kiku).

Started developing power transformers for VTRs. Japanese manufacturers led the world in consumer VTR equipment, supplying both Betamax and VHS formats.

Reclassified to the First Section of the Tokyo Stock Exchange.

Developed a PC power supply for the U.S. company Tandy. It was the company's first large-order switching power supply, producing over 1.5 million units.

From the mid-1970s, switching power supplies became widespread, and the company began external sales to meet the growing demand for high-frequency transformers for TVs and VTRs.

Commercialized a piezoelectric transformer that realizes transformer functions using ceramic. Established a new era with the backlight inverter for LCD displays in thin laptops.

Developed solder paste for semiconductor packages. The following year, obtained certification from a major U.S. semiconductor manufacturer.

Promptly responded to the RoHS directive (2006) by promoting lead-free total solutions. In particular, the lead-free capability of soldering equipment gained a reputation, quickly securing the top share of reflow machines.

Delivered digital broadcasting equipment, including audio equalizers, to each station in preparation for terrestrial digital broadcast.

Started mass production of energy-saving LED lighting by combining LED application technology honed on vending machine display buttons with power supply technology.

The era of practical hybrid vehicles arrived. Vehicle-mounted reactors were adopted in hybrid cars, and mass production began.

Developed black absorptive material and FPC resist for use in smartphones and tablet devices.

Entered the large transformer and reactor market for applications in renewable energy, railways, plants, and transmission and distribution.

Realized the first‑ever gallium oxide (Ga2O3) MOS transistor in the world, paving the way for the commercialization of Japan’s innovative next‑generation semiconductor power devices.

Developed the 'TNV‑Ver.Ⅲ' equipped with convection‑control technology. It meets market demand by reducing maintenance frequency, improving productivity and quality, and further cutting N₂ consumption for energy savings.

Developed the photo‑developable cover‑lay coat 'PICC', enabling flexible functional modules with high‑density mounting, lightweight, thin form factor, and free design.

Transitioned from the First Section to the Prime Market following the Tokyo Stock Exchange’s market classification review.

Developed a gate driver optimized for 3.3 kV SiC/IGBT power modules used in railway vehicle inverters, achieving enhanced protection features along with miniaturization and weight reduction.

Released the 'NTX Series' audio mixing console, compatible with IP‑based next‑generation broadcast systems, for the top‑share audio consoles supplied to domestic broadcasters.

Celebrated the company’s 100th anniversary by launching a commemorative website, publishing a corporate history, holding events, and selling LINE stickers.
