The Fall of Japanese Electronics Giants: What Happened to Sanyo, Panasonic, Aiwa, Kenwood, and Onkyo

How Japan’s Most Iconic Electronics Brands Rose, Fell, and Faded into History

For decades, Japanese consumer electronics brands dominated global markets with innovative products, superior engineering, and household-name recognition. From the 1970s through the 1990s, names like Sanyo, Aiwa, Kenwood, and Onkyo were synonymous with quality audio equipment, while Panasonic (Matsushita) stood as one of the world's largest electronics conglomerates. But as the 21st century progressed, these once-mighty brands faced unprecedented challenges that would fundamentally reshape—or end—their existence.

This is the story of how five legendary Japanese electronics brands lost their way, and what remains of their legacies today.

Sanyo: From Industry Leader to Absorbed Subsidiary

The Glory Days

Sanyo was a Japanese electronics manufacturer founded in 1947 by Toshio Iue, the brother-in-law of Kōnosuke Matsushita, the founder of Matsushita Electric Industrial, now known as Panasonic. The company quickly established itself as an innovator, launching Japan's first spray-type washing machine in 1953 and becoming one of the 3S along with Sony and Sharp in the 2000s.

Sanyo's technological achievements were impressive. In 1992, it developed the world's first hybrid solar cell, and in 2002, it had a 41% share of the global lithium-ion battery market. The company pioneered production of nickel cadmium batteries in 1964, nickel metal hydride batteries in 1990, and lithium-ion batteries in 1994—technologies that would power the modern world.

In its heyday in 2003, Sanyo had sales of about ¥2.5 trillion, making it one of Japan's most successful electronics manufacturers.

The Decline

The fall came suddenly and dramatically. Sanyo fell into a financial crisis as a result of its huge investment in the semiconductor business. The company had bet heavily on chip manufacturing at precisely the wrong time, as competition from South Korean and Chinese manufacturers intensified and profit margins collapsed.

By the 2000s, the company was facing a prolonged shakeout, grappling with competition from China and South Korea. The strength of the yen also made Japanese exports more expensive, putting pressure on manufacturers to merge.

The Panasonic Acquisition

In 2009, Sanyo was acquired by Panasonic, and in 2011, it was fully consolidated as a subsidiary. Panasonic, which was positioning the energy business as a new key business, decided to utilize SANYO's technologies for rechargeable batteries, solar cells, etc. to enhance Panasonic's resources.

The acquisition wasn't about saving Sanyo's brand—it was about acquiring specific technologies and talent. Panasonic Corporation currently sells virtually all of its products and services worldwide under the Panasonic brand, having phased out the Sanyo brand in the first quarter of 2012.

What Remains

Sanyo's iconic neon sign in Piccadilly Circus went dark in 2011, symbolically marking the end of an era. While the Sanyo brand has been largely discontinued, Panasonic reintroduced the Sanyo brand in India, with the launch of Sanyo LED TV range on August 8, 2016, and in October 2014, Panasonic announced its intent to transfer the Sanyo TV unit to Funai in the US market in return for annual royalty payments.

Today, if you see a Sanyo product, it's likely a licensed brand with no connection to the original company's engineering excellence.

Panasonic: Survivor Through Transformation

A Different Story

Unlike the others on this list, Panasonic (formerly Matsushita Electric) hasn't disappeared—but it has dramatically transformed. Panasonic, then Matsushita Electric, was founded in 1918 by Kōnosuke Matsushita as a vendor of duplex lamp sockets.

While Panasonic acquired struggling competitors like Sanyo, the company itself faced massive challenges. In April 2011, it was announced that Panasonic would cut its work force by 40,000 by the end of fiscal 2012 in a bid to streamline overlapping operations.

Strategic Pivot

Panasonic survived by pivoting away from unprofitable consumer electronics toward B2B solutions, automotive components (especially for Tesla and other EV manufacturers), and industrial batteries. The company that once competed in TVs, phones, and audio equipment now focuses on supply chain solutions, factory automation, and energy systems.

The Panasonic brand endures, but the company that bears that name today is fundamentally different from the consumer electronics giant of the past.

Aiwa: Multiple Deaths and Resurrections

The Peak Years

Aiwa was a Japanese consumer electronics brand founded in 1951 and was one of the leading creators of audio products such as speakers, boomboxes and stereo systems. Throughout the 1970s, 1980s, and 1990s, Aiwa competed aggressively with Sony, offering quality audio equipment at more affordable prices.

The company achieved significant innovations, including creating the world's first personal stereo recorder, TP-S30 in 1980, and the HP-J7 earbuds in 1990, designed to be vertically inserted into the ear.

The Sony Era and Decline

The founder Mitsuo Ikejiri served as president until 1969 when Sony purchased a majority share in Aiwa. By 1982, the electronics giant had a 54.6% stake in the company. Despite Sony ownership, Aiwa maintained independent operations and brand identity—until everything fell apart.

In the mid-1990s, Aiwa ignored the "digital revolution" and continued to produce traditional equipment, not paying attention to modern technologies – DVD and the Internet. As a result, in 1999-2002, Aiwa suffered more than $500 million in losses.

Financially-troubled Aiwa was fully purchased by the Sony Corporation, becoming a wholly owned subsidiary effective as of December 1, 2002. On January 8, 2003, Sony announced the rebranding and relaunch of Aiwa as a "youth focused, PC-centric" electronics brand, but this attempt at revival failed within three years.

The American Revival Attempt

An American audio company known as Hale Devices, Inc. were granted the rights to the brand name from Sony in the US market and abroad. The Chicago based company, which was headed by Joe Born, also then renamed itself to Aiwa Corporation. In April 2015 it launched its first Aiwa product, the Exos-9 speaker.

This revival attempt also failed. It was reported in August 2021 that Aiwa Corporation filed for Chapter 11 bankruptcy. Following bankruptcy proceedings, the assets were sold to a new company (Aiwa Acquisitions LLC) affiliated with Sakar International, Inc.

Current Status

Today, Aiwa exists as a zombie brand—a name licensed to various companies with no connection to the original Japanese engineering tradition. A Japanese company, Aiwa Co. Ltd., a subsidiary of Towada Audio holdings, was established in 2017 and creates mainly audio products, while other companies use the Aiwa name under license in different regions.

The Aiwa that audiophiles remember is dead. What exists now are unrelated companies trading on nostalgia.

Kenwood: Merged into Obscurity

The Audio Pioneer

Kenwood Corporation was established on 21 December 1946 as the Kasuga Radio Co. Ltd. in Komagane, Nagano Prefecture, Japan. In 1960, the company was renamed Trio Corporation. The name "Kenwood" was invented by Kasuga as a combination of "Ken" and "Wood", and became more widely recognized than Trio, leading to the company's rebranding.

Throughout the 1970s and 1980s, Kenwood was legendary for high-quality hi-fi audio components, car stereos, and amateur radio equipment. The brand represented Japanese engineering excellence and competed head-to-head with Pioneer, Marantz, and others for audiophile dollars.

The JVC Merger

By the 2000s, Kenwood faced the same challenges as other Japanese electronics makers: crushing competition from cheaper Asian manufacturers, a strong yen making exports expensive, and shrinking demand for traditional audio equipment.

In October 2008, Kenwood merged with JVC to form a new holding company, JVCKenwood. Both companies reported losses in their most recent financial statements leading up to the merger, making the combination a defensive move rather than a position of strength.

On 1 August 2011, JVC Kenwood Holdings, Inc. was renamed to JVCKenwood Corporation and an absorption-type merger was finalized for the JVC and Kenwood subsidiaries.

What Happened to Kenwood

In 2007, Kenwood discontinued its line of consumer audio receivers, home theatre systems, and other home electronics—the products that had built the brand's reputation. Today, JVCKenwood still uses the Kenwood brand name primarily for professional two-way radios and communications equipment.

The Kenwood that audiophiles knew—the company that made legendary amplifiers and receivers—effectively ceased to exist in 2007. The brand name survives, but the soul of the company is gone.

Onkyo: Bankruptcy and Brand Licensing

The Home Theater Leader

Onkyo Corporation was a Japanese consumer electronics company, specializing in premium home cinema and audio equipment, including AV receivers, surround sound speakers and portable devices. The company started under the name of Osaka Denki Onkyo K.K. in 1946.

Through the 1990s and 2000s, Onkyo became one of the most respected names in home theater, particularly for AV receivers. The company offered exceptional value—premium features at mid-range prices—and built a loyal following among home theater enthusiasts.

The Pioneer Acquisition

In March 2015, Onkyo purchased Pioneer Corporation's Home Electronics Corporation, which produces home cinema amplifiers, Blu-ray players and other AV products. This seemed like a smart consolidation move, but it would prove to be the beginning of the end.

The Long Decline

Following the Pioneer acquisition, Onkyo's financial situation steadily deteriorated. The company faced multiple challenges:

• Intense price competition from Chinese manufacturers
• Semiconductor shortages are disrupting production
• Failed acquisition attempts (notably, a 2019 deal with Sound United fell through)
• COVID-19 pandemic impacts
• Shrinking home theater market as consumers shifted to soundbars

After being delisted from the Tokyo Stock Exchange last August, Onkyo saw two of its major subsidiaries file for bankruptcy just last March, including Onkyo Sound Co. Ltd., an Onkyo OEM that sold audio equipment under other brands, and Onkyo Marketing Co. Ltd.

The Final Bankruptcy

On May 13, 2022, Onkyo announced that it was filing for bankruptcy. Total liabilities have been estimated at around ¥3.1 billion ($24 million USD).

However, there's a twist to this story. In May 2021, Voxx International and Sharp Corporation began negotiations with Onkyo to purchase its home audiovisual division. Voxx's subsidiary Premium Audio Company (PAC) entered a joint venture with Sharp to acquire the business, which includes the Onkyo and Integra brands, for $30.8 million.

Brand Survives, Company Dies

Onkyo, Integra, Pioneer, and Pioneer Elite-branded products continue to be distributed by PAC via its 11 Trading Company subsidiary. The original Japanese company is dead, but the brand names live on under new ownership.

A professor noted in The Asahi Shimbun that Onkyo prioritized its manufacturing quality to the detriment of its adaptability to market conditions, with the advent of the smartphone killing off the middle segment of the hi-fi market.

Common Threads: Why They All Failed

1. The Asian Manufacturing Challenge

All five brands faced crushing competition from South Korean manufacturers (Samsung, LG) and later Chinese companies that could produce similar products at dramatically lower costs. Japanese manufacturers, with higher labor costs and expensive yen, couldn't compete on price.

2. Failure to Embrace Digital Transformation

Most of these companies were slow to adapt to the digital revolution. Aiwa clung to cassette technology. Kenwood and Onkyo were late to embrace streaming and wireless audio. They optimized products for a world that was disappearing.

3. The Strong Yen Problem

Throughout the 2000s and 2010s, a strong Japanese yen made exports expensive, eroding profit margins and making Japanese products less competitive in global markets.

4. Market Consolidation

The consumer electronics market consolidated dramatically. Companies needed enormous scale to compete—something mid-sized players like Aiwa, Kenwood, and Onkyo couldn't achieve.

5. Changing Consumer Behavior

The smartphone killed entire product categories. Portable audio players, standalone GPS devices, digital cameras, and even dedicated audio components saw demand collapse as smartphones became all-in-one devices.

6. Resistance to Change

Japanese corporate culture, with its emphasis on consensus and tradition, often made these companies slow to respond to rapid market changes. By the time they recognized the threat, it was often too late.

Lessons from the Fallen

Quality Isn't Everything

All these brands were known for quality and engineering excellence. It wasn't enough. Onkyo's professor was right: prioritizing manufacturing quality over market adaptability proved fatal.

Brands Without Companies

The survival of brand names (Sanyo, Aiwa, Onkyo) without their original companies shows that brands have value even when the companies die. But these zombie brands often disappoint customers expecting the quality of the originals.

Merger Desperation

The Kenwood-JVC and Onkyo-Pioneer mergers were defensive moves by struggling companies. Combining two struggling companies rarely creates one strong company—it often just delays the inevitable.

Technology Transitions Are Brutal

The transition from analog to digital, from physical media to streaming, from dedicated devices to smartphones—each shift killed established players who couldn't adapt quickly enough.

What Remains Today

Sanyo: Brand name licensed to various manufacturers; original company absorbed by Panasonic

Panasonic: Survives but dramatically transformed, focused on B2B and automotive/industrial markets

Aiwa: Zombie brand licensed to multiple unrelated companies worldwide

Kenwood: Name used by JVCKenwood primarily for professional communications equipment

Onkyo: Brand owned by Voxx/Sharp joint venture; original Japanese company bankrupt

The Broader Implications

The fall of these Japanese electronics giants represents more than corporate failures—it symbolizes a fundamental shift in global manufacturing and technology leadership. Japan, which dominated consumer electronics from the 1970s through the 1990s, lost that position to South Korea, China, and increasingly, companies from other emerging markets.

Today's electronics landscape is dominated by:

• South Korean giants: Samsung and LG
• Chinese manufacturers: Xiaomi, TCL, Hisense, BYD
• American tech companies: Apple, Google, Amazon (for smart home/audio)
• European survivors: Philips, Bose (US)

The Japanese brands that survive—Sony, Panasonic, Sharp—have all dramatically transformed their business models, often exiting or deprioritizing consumer electronics in favor of B2B markets, components, or industrial applications.

Conclusion: The End of an Era

For those who grew up in the golden age of Japanese electronics, the fall of Sanyo, Aiwa, Kenwood, and Onkyo feels personal. These weren't just brands—they were gateways to better sound, innovative technology, and aspirational quality. A Kenwood amplifier, an Aiwa boombox, an Onkyo receiver, or a Sanyo product represented not just a purchase, but entry into a world of superior engineering.

But nostalgia doesn't save companies. The market moves on, technology evolves, and companies that can't adapt disappear—no matter how legendary their past.

The lesson isn't that quality doesn't matter, or that engineering excellence is irrelevant. The lesson is that in fast-moving technology markets, adaptability matters more than perfection, speed matters more than consensus, and understanding where the market is going matters more than being the best at what the market no longer wants.

The golden age of Japanese consumer electronics is over. What remains are lessons in corporate mortality, cautionary tales about the dangers of complacency, and fading memories of brands that once meant everything to millions of consumers worldwide.

The giants have fallen. And they're not coming back.
