Japanese cross‑party legislators visit Taiwan, vow to push Taiwan Relations Act legislation

A new chapter in substantive diplomacy and parliamentary outreach between Taiwan and Japan was written this month. On the 7th, a seven‑person, cross‑party delegation of Japanese lawmakers arrived in Taiwan to begin an official visit, led by Conservative Party senator Haruo Kitamura. In a public remarks after landing, Kitamura stated unequivocally that the core purpose of the delegation’s trip was to convey Japan’s strong commitment to preserving peace and stability across the Taiwan Strait to both Taiwanese society and its government. He also pledged that, upon returning to the Diet after the itinerary concluded, the delegation’s members would actively promote legislation that could become a Japanese counterpart to the United States’ Taiwan Relations Act and Taiwan Travel Act, with the aim of deepening cooperation with democratic partners such as Taiwan and the United States to collectively safeguard peace and stability in the Indo‑Pacific.

A review of recent Taiwan‑Japan relations shows that, despite the absence of formal diplomatic recognition for decades, the two sides have drawn increasingly close through parliamentary diplomacy, trade, and civil exchanges. In the context of escalating geopolitical risks, Japanese political circles are now paying the highest level of attention to Taiwan’s security in decades. Former Prime Minister Shinzo Abe’s strategic articulation that “a trouble for Taiwan is a trouble for Japan, that is, a trouble for the Japan‑U.S. alliance” profoundly shaped revisions of Japan’s defence and security policy documents and resonated throughout Japanese society and across party lines. The present cross‑party delegation headed by Kitamura is a concrete expression of this long‑standing, anti‑China, pro‑Taiwan stance and a deepening of the Taiwan‑Japan partnership, demonstrating bipartisan support in the Japanese Diet for Taiwan’s democratic defence.

The proposed Japanese versions of a “Taiwan Relations Act” and a “Taiwan Travel Act” that Kitamura referenced carry profound historical significance in international politics and diplomatic practice. The United States enacted its Taiwan Relations Act in 1979, establishing a robust domestic‑law foundation for unofficial U.S.–Taiwan ties and authorising the supply of defensive weapons to enable Taiwan’s self‑defence. More recently, the U.S. passed a Taiwan Travel Act encouraging inter‑governmental visits at all levels. Japan, by contrast, has been constrained by the 1972 Japan‑China Joint Communiqué, lacking a comparable statutory framework. Should the Japanese Diet eventually succeed in enacting a Japanese Taiwan Relations Act, it would supply a clear legal basis for security cooperation, intelligence sharing, and high‑level interactions between Japan and Taiwan, moving away from the previous reliance on administrative discretion and informal understandings. Such a development would be pivotal for reinforcing collective deterrence across the Indo‑Pacific.

From a geopolitical and regional‑security perspective, the safety of the Taiwan Strait is no longer a bilateral cross‑strait issue alone; it is a core factor affecting global supply chains, freedom of navigation, and the survival of the democratic camp. Japan, a close neighbour of Taiwan, has its southwestern islands just a short distance from the island, meaning that any conflict in the Strait would strike directly at Japan’s national security and maritime lifelines. Consequently, the cross‑party push in Japan for pro‑Taiwan legislation is driven not only by democratic solidarity but also by Japan’s own defence imperatives. Kitamura’s emphasis on cooperation with Taiwan and the United States reflects a burgeoning “U.S.–Japan–Taiwan” security dialogue and substantive partnership that is becoming the most important bulwark for East Asian peace, increasing strategic pressure on the People’s Republic of China’s attempts to alter the status quo through grey‑zone tactics and military coercion.

Looking ahead, the key question for Taiwan’s Ministry of Foreign Affairs and the international community will be how the Japanese lawmakers translate the consensus reached during the visit into concrete parliamentary proposals and enacted policies after they return to Tokyo. Advancing such legislation traditionally requires navigating complex party negotiations and diplomatic pressures, especially as Beijing is expected to mount vigorous political and economic retaliation against any Japanese Taiwan Relations Act initiative. Nonetheless, the decision of a bipartisan Japanese delegation to visit Taiwan in person and make explicit commitments sends a clear signal of democratic unity against authoritarian expansion. The trip has not only deepened people‑to‑people and parliamentary ties between Taiwan and Japan, but also placed a strategically significant piece on the Indo‑Pacific security board.
