Environmental Impact: Use and Conservation of Groundwater

The development of Kumamoto’s semiconductor industry heavily depends on its rich water resources, raising significant issues concerning the conservation of groundwater resources. Semiconductor factories require large quantities of pure water, leading to the extensive use of groundwater for industrial purposes.

This raises concerns about the long-term depletion of water resources and lowering of groundwater levels. Additionally, the environmental impact of wastewater discharged from factories must be considered. These issues extend beyond Kumamoto and represent significant challenges for the sustainability of water resources on a global scale.


Social Challenges: Infrastructure Pressure due to Population Increase

The entry of major companies like TSMC creates numerous employment opportunities, leading to a significant influx of people. In Kumamoto Prefecture, this population increase puts considerable pressure on infrastructure, causing issues like traffic congestion, housing shortages, and overburdening of public facilities like schools and hospitals.

These social challenges directly affect the quality of life in local communities, necessitating a balance between sustainable industrial development and social harmony.



Comparative Analysis with Other Regions

Comparison with TSMC’s Factory in Arizona, USA

TSMC’s factory construction in Arizona, USA, has different characteristics compared to the factory in Kumamoto. The Arizona factory employs more advanced technology (5nm process) and has a different level of production capacity and technical expertise compared to the Kumamoto factory (22-28nm process).

This difference influences the industrial direction and focus on technological development in both regions. The adoption of more advanced technology in the Arizona factory serves as a reference for addressing the technological challenges faced by Kumamoto and enhancing its competitive strength in the market.


Kumamoto’s Unique Conditions and Challenges

Kumamoto can establish a unique position in the semiconductor industry by leveraging its abundant water resources and geographical advantages. However, it also faces challenges such as environmental conservation, harmonization with the local community, and infrastructure development.
