The company was founded on June 20, 1951, as AIKO Denki Sangyo Co., Ltd., manufacturing microphones, and changed its name to Aiwa Co., Ltd. , on March10, 1959. Mitsuo Ikejiri served as president until 1969.
The company was a leading manufacturer of audio products, including headphone stereos, minicomponent stereo systems, portable stereo systems, minidisc players, CD and cassette players, and car stereo systems throughout the 1970s, 1980s, and 1990s. Nearly 86 percent of company revenues were derived from such audio products. 12 percent came from products such as televisions and VCRs, and the remaining two percent from computer peripherals and other life products.
Aiwa marketed Japan's first boombox, the TPR-101 (left), in 1968, as well as the first cassette deck, TP-1009. In 1980, Aiwa created the world's first
personal stereo recorder, TP-S30 (right). Despite Sony being the major shareholder, healthy competition between the two brands was believed to be profitable. In 1990, Aiwa created the HP-J7 earbuds, designed to be vertically inserted into the ear. In 1993, the first CD+G-compatible portable CD player, the XP-80G, was made.
Apart from audio products, Aiwa also has been present in other industries. The company also made and sold video products such as VCRs, color televisions, DVD players, and digital satellite television tuners. Aiwa was also involved in the production of computer peripheral devices, such as modems, terminal adapters, and speakers, and what the company termed "life amenity products," such as air cleaners and humidifiers. In 1995, it released a PHS mobile phone, called the PT-H50, which was made for the DDI Pocket network in Japan. That same year, an electric toothbrush, the HA-C10, was released.
Aiwa manufactured more than 89 percent of its output outside Japan, with a heavy emphasis on the lower-cost southeast Asian nations of Singapore, Malaysia, and Indonesia. The company was also heavily dependent on overseas sales, with more than 80 percent of total revenues being generated outside Japan, with 43 percent in North and South America, 25 percent in Europe, and 13 percent in areas of Asia outside Japan and in other regions.
Although not then officially an affiliated company of consumer electronics giant Sony Corporation, by 1982, Sony had a 54.6% stake in the company, effectively giving it a majority control.
With growing competition throughout the late 1990s, the company slid towards bankruptcy. In March 2001, the company's president, Masayoshi Morimoto, announced the halving of its workforce, following a second consecutive loss–making year.

Acquisition by Sony
The troubled company was then fully purchased by Sony Corporation. As of December 31, 2003, Aiwa ceased to be a separate company and became a wholly owned division of Sony.
In January 2004, Sony announced the rebranding and relaunch of Aiwa as a "youth focused, PC-centric" electronics brand. A new logo was presented to the world's media along with a statement of Sony's intention to invest in and "revitalize" the Aiwa brand. The direction proposed was to capitalize on the growing trend among personal-computer-literate teenagers and young adults to use their PCs for all forms of entertainment (television, films, music, chat). It was also used to expand in markets where Sony is not as strong.
However the new direction of Aiwa under Sony did not meet consumer and sales expectations. On January 21, 2005, new product development ended, and by 2006, Aiwa products were discontinued and no longer sold in the market. Sony announced the termination of the brand entirely on May 14, 2008.
As of January 2014, the Aiwa website still existed to provide customer-support telephone numbers for some territories and regions, but it also contained many broken links and blank pages. In other regions, such as Europe, it redirected to a page on the Sony website stating that the Aiwa website had closed.
Aiwa USA (2015–)
In 2015, Dormitus Brands, a Chicago-based brand acquisition company run by Mark Thomann, acquired the trademark right in the U.S. Thomann looked to pair the brand with a company that was innovating in the audio industry, eventually leading to a deal with Hale Devices, Inc., headed by Joe Born. Hale Devices renamed itself into Aiwa. The Aiwa brand was formally relaunched in March 2015, releasing its first product, the Exos-9, a wireless Bluetooth speaker.
Aiwa Co., Ltd. (2017–)
On April 11, 2017, Japanese audio equipment manufacturer Towada Audio announced that it acquired the Aiwa brand rights from Sony and would produce Aiwa-branded audio and record player products.
