Japan recently reiterated its unchanged stance on Taiwan, emphasizing its ongoing support for peace and stability in the Taiwan Strait while reaffirming its formal commitment to the "One China" policy in line with its longstanding agreements with China. The Japanese Prime Minister, Sanae Takaichi, caused controversy with remarks in early November 2025 suggesting that Japan could consider military intervention if China were to use force against Taiwan, framing such a scenario as a potential existential threat to Japan. These comments have led to significant diplomatic friction with Beijing, including warnings from China, protests, travel advisories, and calls for Japan to retract the statements.

Despite this heated exchange, Japanese officials have insisted that their fundamental position regarding Taiwan has not changed: Japan recognizes the government of the People's Republic of China as the sole legal government of China, "fully understands and respects" China's position that Taiwan is part of its territory, and limits official exchanges with Taiwan to private and regional matters. Japan continues to publicly stress the importance of maintaining peace and stability in the region, urging restraint from all sides.
