What Happened to Toshiba?

From inventing flash memory and the laptop to an accounting scandal, a failed nuclear bet and selling off its own crown jewels. The unwinding of a Japanese giant.

Toshiba built the memory and laptops that power the modern world, but a 2015 accounting scandal and a failed US nuclear bet cost it its independence - and it unwound itself selling off those very innovations.

The conglomerate that helped build the digital age

For much of the twentieth century Toshiba was a towering Japanese conglomerate - and it helped invent the technology the modern world runs on. It developed NAND flash memory, the storage behind every smartphone, and it helped create the portable laptop.

Then it all unravelled. An accounting scandal, a disastrous nuclear bet abroad, and a slow-motion sell-off of its own divisions left the company a shell of the giant it used to be.

Winning the memory and laptop era

Toshiba formed in 1939 from the merger of Tokyo Shibaura and Tokyo Denki, instantly a force in Japanese heavy and electrical industry. Through the postwar decades it became a household name in consumer electronics, and in 1987 it developed NAND flash memory - the chip that would end up in cameras, phones and drives around the world.

It was also a laptop pioneer. For years Toshiba's notebooks were standard-issue for business, and its semiconductor business made it one of the world's biggest chipmakers.

The accounting scandal

In 2015 Toshiba admitted it had overstated profits - by around $1.2 billion - across several years. The scandal forced out its chief executives, shattered its reputation for integrity, and gave the company a credibility problem it never recovered from.

The fraud was a symptom of the deep pressure it was under, and it came right as other problems were piling up.

The nuclear mis-bet

Toshiba had bought Westinghouse, one of the world's big nuclear-reactor builders, betting on a US nuclear renaissance. That bet went catastrophically wrong, driving multibillion-dollar writedowns and pushing the company toward financial collapse.

Combined with the accounting scandal, the nuclear debacle left Toshiba with billions in losses and no easy way out.

Selling the crown jewels

To survive, Toshiba sold the divisions that had made it famous. In 2018 its prized memory business went to a Bain-led consortium as Kioxia. In 2020 it sold its laptop unit, dynabook, to Sharp. It slimmed down to power, infrastructure and a shrinking electronics presence.

It was the reverse of a growth story: a company liquidating its own core to pay for past mistakes.

Where is Toshiba now?

In 2023 Toshiba de-listed from the Tokyo exchange after a buyout led by private equity, ending its long run as a public giant. The name still appears on power and infrastructure equipment, but the consumer-electronics-and-memory powerhouse is gone.

The story is a cautionary one: even the best-engineered conglomerates can be undone by a confidence scandal and one catastrophic bet, and then have to sell what they were built on to survive.
