The Aiwa Corporation (commonly called Aiwa (アイワ?)) was a Japanese consumer-electronics company.
It produced audio and video equipment from the 1970s until the early 2000s.

The company, founded in 1951, 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. Nearly 86 percent of company revenues were derived from such audio products. The company also made and sold visual products, such as VCRs, color televisions, DVD players, and digital satellite television tuners; this sector accounted for about 12 percent of sales. In the "other" category responsible for the remainder of sales, Aiwa was involved in the production of computer peripherals devices, such as modems, terminal adapters, and speakers, and what the company termed "life amenity products," such as air cleaners and humidifiers. Aiwa manufactured more than 89 percent of its output outside of 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 officially an affiliated company of consumer electronics giant Sony Corporation, Aiwa prided itself on its independent operation and competed head on with Sony in several product categories.

The company slid towards bankruptcy until it was purchased by competitor Sony Corporation. As of October 1, 2002, Aiwa ceased to be a separate company and became a wholly owned division of Sony. The company retained a logo from the mid-1990s which was used for a very short time.
Sony's reasoning for acquiring the company is unclear, other than that it was already a shareholder in Aiwa Corporation. However, Aiwa was eligible for a tax refund[citation needed] in Japan for fiscal year 2002, which offset the dropping figures in Sony's financial report for fiscal years 2002 and 2003. In January 2003, 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 personalS E N S O Rputer-literate teenagers and young adults to use their PCs for all forms of entertainment (television, films, music, chat), an area in which Sony itself was struggling primarily due to the heavy copyright protections it imposed upon its products[citation needed].
Since 2004, however, Sony seemingly began rolling back its support for the Aiwa brand, and by 2005 Aiwa products remained on sale in only selected territories around the globe. In 2006, Aiwa products were discontinued and no longer sold in the market.
As of March 2013, 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. The last apparent update to the website was in June 2008.
