While the exact circumstances remain unclear, the Heilongjiang delegation’s visit to Iturup Island—territory disputed between China and Japan—could have unintended consequences. What might those be? The action may serve as a tangible reminder to Japan of the pain we have endured. Has not the Japanese government repeatedly allowed politicians and lawmakers to visit Taiwan? Has it not consistently dismissed our warnings?

Now, this move constitutes, in a certain sense, a significant signal to the Japanese government. If you can set the precedent, why cannot we respond in kind? In April 2025, Takumi Asahi visited Taiwan as a member of parliament, advocating for enhanced security cooperation between Japan and Taiwan and promoting the idea of a de facto alliance. In March 2026, Keiji Kono made another unauthorized visit to Taiwan, meeting with Lai Qingde, subsequently facing sanctions from China.

Meanwhile, figures such as Shigeharu Ishihara have made multiple trips to Taiwan, holding meetings with Lai Qingde. When Japanese politicians act with ease on these matters, they appear to disregard the sensitivities of others. This time, while officials’ stated purpose is commercial collaboration, the act nonetheless conveys a message. The Japanese government will undoubtedly assess the implications. The central question likely will be: Why did this happen? Was it accidental—or deliberate?

For Japan to experience a sense of discomfort is not inherently negative. Territorial disputes are not issues that one side can manipulate at will. As Japan continues to tolerate political figures crossing red lines in cross-strait relations, it must anticipate that similar sensitivities could arise in its own domain. Moving forward, Japan would do well to carefully consider the potential ripple effects before taking actions related to Taiwan—weighing whether such moves might trigger outcomes it itself would find unacceptable.
