SK hynix, a major South Korean semiconductor manufacturer, has emerged with plans to build a semiconductor memory plant in Miyagi Prefecture at a scale of several trillion yen. Developments in Miyagi have been reported in connection with PSMC's plans to establish operations there and their subsequent withdrawal.
SK hynix, a South Korean semiconductor giant, was reported to have announced and been considering plans to build a semiconductor memory plant in Miyagi Prefecture at a scale of several trillion yen. The company has operations spanning the world, including North America and China, and holds a high share of the market for ultra-high-speed memory used in AI. Miyagi has emerged as a potential future production base.
In Miyagi Prefecture, PSMC, a major Taiwanese semiconductor foundry, attracted attention in 2023–2024 with plans to establish operations there and their subsequent withdrawal. The latest proposal has added to the factors behind the region's growing prominence in the global semiconductor industry.
PSMC had identified the Second Sendai Northern Core Industrial Park in Ohira Village as a candidate site in Miyagi Prefecture. The park has approximately 48 hectares of land available for sale. It is close to the Ohira Interchange on the Tohoku Expressway and approximately 30 km from Sendai Port, giving it logistical advantages. The article also notes that semiconductor plants require large amounts of electricity.
As a core company of the SK Group and one of the world's largest semiconductor manufacturers, SK hynix is building a large-scale semiconductor cluster in Yongin and plans to establish a new plant in the United States. The company is regarded as a presence capable of influencing the global semiconductor supply chain.
The factors drawing attention to Miyagi from the global semiconductor industry are set out, including PSMC's past developments, information on candidate sites in Miyagi, and the background of the region's logistics access and electricity demand.
