History

Management philosophy of Tamura Tokumatsu: We do not necessarily desire to become a large company, but our products must be the finest in the world. This is our mission.

Tamura Corporation was founded in 1924 as Tamura Radio Store and is one of Japan’s oldest electronics companies. Beginning with the introduction in 1935 of an in-house developed high-quality radio receiver transformer, Tamura has developed a stream of products, including a wide variety of transformer-related products, electronic chemicals, reflow soldering systems, LED lights, broadcast audio mixing consoles, and wireless microphones.

【The Early Years】1924-1938

1924		Tamura Radio Store is founded in Tokyo’s Shinjuku district a year before the start of radio broadcasting in Japan.
1932		The company, which at first imported, sold, and repaired radios, receives an order for electric phonographs from record manufacturer Polydor and simultaneously begins sales of own brand phonographs.
1934		The company develops in-house the P72 low-frequency transformer, which greatly improves sound quality.
1936		Tamura moving-coil microphones are delivered for use at Asakusa InternationalTheater. They are subsequently introduced at broadcasting stations nationwide.

【Transition from a Radio Store to a Components Manufacturer】1939-1945

1939		Tamura Corporation is established, signaling an ongoing transformation from local radio store to manufacturer of world-class products.
1941		Tamura Corporation’s Kashiwagi Laboratory opens. Tamura develops products such as communication instruments and repeating coils, laying the foundation for the communication equipment business.
1944		The Higashi-Oizumi Factory is completed in Higashi-Oizumi, Nerima Ward, Tokyo, and most business operations are transferred to the new factory.

【Post-war Recovery】1946-1967

1955		The first Japanese-made transistor radio, containing a Tamura compact transformer, is introduced. The radio becomes a blockbuster hit product, and Tamura begins full-scale mass production of consumer-use products.
1956		Tamura develops SOLDERITE flux, Japan’s first noncorrosive soldering flux, and establishes a specialized chemistry laboratory within the company.
1961		Coinciding with the soaring popularity of television in the home, Tamura develops its first audio mixing console for use as broadcast equipment.
1962		Tamura enters the low-power wireless device business. Tamura wireless microphones installed at stadiums for the Tokyo Olympic Games (1964) are used in recording of the official documentary film.

【International Expansion and Journey to the Pinnacle of the Consumer Business】1968-1979

1968		Vacuum tubes give way to transistors, and the use of printed circuit boards spreads rapidly. Tamura develops its first automated soldering system and subsequently provides support for the mass-production of home appliances.
1969		Tamura establishes Taiwan Tamura Denshi Co., Ltd. as its first overseas production base with the objective of securing manpower and reducing costs to accommodate an increase in orders from the U.S.
1972		Building on its track record for highly reliable transformers, Tamura begins development of transformers and coils for use in Japan’s first satellites: the Ume ionosphere sounding satellite (ISS) and the Kiku engineering test satellite (ETS-1).
1972		Japanese manufacturers introduce the world’s first consumer VTRs, and Tamura supplies power transformers for both the Beta format and the VHS format.

【Advancing Digitization】1980-1999

1984		Developed a power supply for PCs for TANDY Corporation in the U.S. This was the company's first large-volume order for a switching power supply, with over 1.5 million units produced.
1988		From the mid-1970s, switching power supplies became widespread, and in response to the increased demand for high-frequency transformers for televisions and VTRs, the company began external sales.
1994		Tamura succeeds in practical application of a piezoelectric transformer, using ceramics to achieve the functionality of a transformer. This paves the way for LCD backlight inverters used in laptop computers, which require thin components.
1995		Tamura develops solder paste for semiconductor packages, which is approved for use by a major U.S. semiconductor manufacturer the following year.

【Heightening of Environmental Consciousness】2000-2009

2000		Tamura implements comprehensive lead-free solutions to promptly comply with enforcement of the RoHS directive in 2006. The lead-free response for soldering systems is especially popular and swiftly propels Tamura to global market share leadership in reflow devices.
2003		Tamura audio mixing consoles and other digital broadcasting facilities are delivered to television stations in preparation for terrestrial digital broadcasting.
2008		Tamura begins mass production of energy-saving LED lights made possible by the fusion of LED application technologies developed for vending machine display buttons and power source technologies.
2009		The era of practical hybrid vehicles arrives. Tamura reactors are adopted for use in hybrid vehicles, and mass production begins.

【Soaring Popularity of Smartphones and Expansion into the Energy Market】2010-2019

2010		Tamura develops resists for black absorbers and FPCs and applies them to smartphones and tablets.
2010		Tamura enters the market for large transformers and reactors used in renewable energy, railway, plant, power transmission and distribution, and other applications on a full-scale basis.
2013		Tamura achieves the world’s first gallium oxide (Ga2O3) MOS transistor, opening the way to practical application of innovative next-generation semiconductor power devices from Japan.
2017		Developed the 'TNV-Ver.Ⅲ' equipped with convection control technology. This product adresses market demands by reducing maintenance frequency, improving productivity and quality, and achieving a reduction in N2 consumption, contributing to energy savings.

【Transformation to create a robust future for the 100th anniversary & beyond】2020-

2022		Developed photo imageable coverlay coat 'PICC', enabling high-density mounting, light weight, thinness, and greater design flexibility for circuit board.
2023		Developed a gate driver optimized for 3.3kV SiC/IGBT power modules used in railway vehicle inverters. In addition to enhanced protection features, it achieves a compact and lightweight design.
2023		Released the 'NTX Series' audio mixing console, compatible with IP-based next-generation broadcasting systems, in the audio mixing console segment where we hold the top market share among Japanese broadcasters.
2024		To commemorate our 100th anniversary, the company launched a dedicated website, published a company history book, held events, and released LINE stickers for sale.
