Kumamoto Home to 64 Companies with Revenue Larger than JPY 10 Billion

On 14 April at 9:26pm, Kumamoto Prefecture, located in the Kyushu region of

Japan, was hit by an earthquake with a seismic intensity of 7 (Japanese

standard). Aftershocks with high seismic intensity have been continuing since.

Currently, nine people have been confirmed dead, with more than 860 people

injured. Fortunately, there was no tsunami this time.

Although the overall situation remains unclear, we have extracted a list of

companies headquartered in Kumamoto to try and gain a better understanding

of the economic impact on the prefecture. There are 13,710 companies

headquartered within Kumamoto, of which 64 companies have revenue of

more than JPY 10 billion (including companies not included in SPEEDA). The

number of companies in each city is noted in the map below, along with the top

10 companies on a revenue basis.

Kumamoto Prefecture a Hub for Semiconductor Manufacturing

In addition to the companies listed above, there are a number of companies

that are headquartered outside of Kumamoto but own factories within the

prefecture. Notably, Kumamoto/Kyushu is known as a semiconductor hub in

Japan. For example, Sony has three image sensor fab manufacturing plants in

Kyushu, with one located in Kumamoto Prefecture.

Below are lists of companies and factories related to the semiconductor

industry in Kumamoto, sourced primarily from the “Kyushu Semiconductor

Related Supply Chain Map” (Kyushu Semiconductor & Electronics Technology

Innovation Association / SIIQ).

Current Situation

News reports and company press releases have reported minor damage to

factories such as cracks in the walls. However, there has not been any

significant damage confirmed so far.

Sony, Mitsubishi Electric, and Horiba have announced that they will suspend

their plant operations today.

Sony’s image sensor is used for major smartphones, including the iPhone.

Mitsubishi Electric’s power semiconductors are said to be used for Toyota’s

best-selling hybrid car, the Prius.

Finally, Honda has its main domestic bicycle factory located in Kumamoto.

NewsPicks’ Editorial Industry/Corporate Research Team has investigated the

situation within a few hours of the earthquake and learned that Honda has

decided to close the factory until the afternoon of 15 April. Resuming of

operations will be determined by further inspection on the damage situation.

Meanwhile, the safety of the plant’s workers is yet to be confirmed.
