Relations between Japan and Taiwan have reached unprecedented heights due to shared values, economic partnerships, and cultural exchanges. Katayama noted that these ties are characterized by horizontal cooperation, which is vital for mutual trust and beneficial collaboration. The historical context includes Taiwan's strategic geographic proximity to Japan, which plays a significant role in regional security dynamics, especially amid rising tensions with China.

Ryo Kiridori, a research fellow at the National Institute for Defense Studies, articulated three strategic reasons for Japan's focus on Taiwan: its geographic proximity, its role in critical sea lines of communication, and its economic significance. Kiridori pointed out that Taiwan is only 111 kilometers from Japan's Yonaguni Island and is a key player in maritime traffic, which is vital for Japan's economy. He noted that Japan's reliance on Taiwanese semiconductors, which account for about two-thirds of global output, further underscores this dependency.

Katayama identified several areas for further collaboration between Taiwan and Japan, including disaster prevention, environmental energy, public health, and the security of undersea cables. He mentioned that both nations signed a digital trade agreement in December, which aims to enhance bilateral cooperation in technology and artificial intelligence. This agreement builds on previous e-commerce initiatives and lays the groundwork for deeper collaboration.

Despite the positive outlook on Japan-Taiwan relations, some experts caution against interpreting Japan's stance as a definitive shift towards strategic clarity regarding Taiwan. Kiridori noted that ambiguities remain in Japan's decision-making process regarding military responses to potential threats involving Taiwan. He emphasized that any response would be assessed on a case-by-case basis, aiming to avoid confrontation, particularly between the United States and China.

Katayama remarked on the importance of trust in Japan-Taiwan relations, stating, “Trust is a crucial foundation of Japan-Taiwan relations, and mutually beneficial cooperation built on trust is essential.” Kiridori echoed this sentiment, expressing Japan's desire to prevent destabilization in the Taiwan Strait and avoid confrontation with China.
