Taiwan and Japan are deepening their semiconductor cooperation to address economic and national security challenges. Former Japanese Defense Minister Kihara Minoru emphasized that semiconductors have become crucial for Japan’s economic future and defense strategy. He urged stronger Taiwan-Japan semiconductor cooperation as a way to deter potential conflicts in the region.
Speaking at the Taiwan-Japan Semiconductor Alliance Seminar in Tokyo, Kihara highlighted Taiwan’s critical role in global semiconductor manufacturing. He pointed out that Taiwan Semiconductor Manufacturing Company (TSMC) dominates the advanced chip market. Any disruption in semiconductor supply, he warned, could severely impact Japan’s industry and economy.
Kihara also cautioned against conflict in the Taiwan Strait, stating such an event would have devastating consequences worldwide. He stressed that diplomacy and dialogue remain the top priorities to maintain peace. At the same time, he called on Japan, Taiwan, and their allies to strengthen deterrence against aggression.
In addition to Japan and Taiwan, the United States plays a vital role in the evolving semiconductor landscape. Former Taiwan Economics Minister Wang Mei-hua spoke at the seminar, acknowledging the U.S. push for more investments from Japanese and Taiwanese firms. She noted that Taiwan’s major electronics companies, including Wistron and Quanta Computer, are expanding production in the U.S.
Despite concerns that TSMC’s growing U.S. presence could reduce Taiwan-Japan ties, Wang assured that cooperation remains essential. She highlighted TSMC’s plans to build a second semiconductor fab in Kumamoto, Japan, alongside increased research and development investments. These moves demonstrate the ongoing commitment to semiconductor cooperation between the two countries.
Industry experts agree that semiconductors are central not only to economic growth but also to national security. The global reliance on Taiwan’s semiconductor production makes collaboration vital for supply chain stability. Japan’s efforts to secure semiconductor materials reflect a broader strategy to protect its technological edge.
Looking forward, Taiwan and Japan aim to deepen their partnership further. They plan to consolidate alliances with the United States and other like-minded nations. The focus remains on maintaining regional peace while ensuring stable access to critical semiconductor resources.
In summary, semiconductor cooperation between Taiwan and Japan is becoming a cornerstone of regional security and economic stability. Both governments recognize that uninterrupted chip supplies and strong diplomatic ties are key to facing future challenges.
