Okinotorishima: Japan lodges protest against China’s survey ship activities in its claimed EEZ, while Beijing rejects legitimacy.
- Japan protested against China’s maritime research activities in its claimed EEZ near Okinotorishima without prior consent.
- China rejected Japan’s allegations, arguing Okinotorishima is a reef, not an island, hence invalid for establishing EEZ rights.
- Beijing emphasized its actions are a lawful exercise of high-seas freedoms under international law.

The Dispute Surrounding Okinotorishima
The ongoing territorial and maritime disputes between Japan and China remain a focal point in regional geopolitics, with the latest contention revolving around China’s research vessel’s activities in the waters near Okinotorishima. Japan considers these waters part of its exclusive economic zone (EEZ) and protested against the unconsented activities. However, China countered with a rejection of the protest, claiming that under international law, Okinotorishima does not qualify as an island that can generate an EEZ.
Japan’s Chief Cabinet Secretary Hayashi Yoshimasa lodged a formal protest, emphasizing that maritime scientific research within Japan’s claimed EEZ requires Tokyo’s prior consent. The presence of China’s maritime research ship in these waters earlier this week was consequently flagged as a violation of sovereign rights under the United Nations Convention on the Law of the Sea (UNCLOS). Beijing, however, rebutted the claim during a press briefing, describing its conduct as a lawful and rightful “exercise of freedom of the high seas.”
Legal Interpretations and International Implications
At the heart of the matter lies a disagreement over the legal status of Okinotorishima. Japan asserts the reef qualifies as an island capable of generating an EEZ and continental shelf. This categorization secures resource rights over large swathes of adjacent waters, benefiting Japan’s economic and strategic positioning in the Pacific. However, China has consistently maintained that Okinotorishima, being a reef, lacks the criteria required to form the basis for EEZ claims based on UNCLOS standards. Beijing argues that Japan’s actions to reinforce its claim, such as artificial construction to extend Okinotorishima’s landmass, contravene basic principles of international law.
This debate holds broader geostrategic ramifications as it underscores the ongoing power struggle for dominance in the Asia-Pacific region. As maritime routes and underwater resources gain prominence in global economics, disputes of this nature are set to determine future territorial alignments and cooperation frameworks.
Regional and Global Reactions
The contention between Japan and China reflects wider concerns among neighboring nations and global powers about the potential escalation of territorial disagreements in the region. Other countries, such as South Korea and the Philippines, have faced similar standoffs with China over maritime claims. With the South China Sea disputes already compelling global stakeholders to reassess their maritime security and diplomatic strategies, a parallel tension in the Pacific waters may elevate anxieties further.
Intriguingly, Beijing’s argument over Okinotorishima being a reef aligns with international interpretations by some scholars and institutions. Still, Japan’s insistence on its position highlights the strategic need to consolidate its maritime boundaries amidst an increasingly assertive Chinese presence on the high seas.
Commentary
Understanding the Legal Tensions
The disagreement over Okinotorishima is not just about the legal classification of a geographic feature—it is also a litmus test for international maritime law. China’s dismissal of Okinotorishima as a reef rather than an island and its repeated emphasis on exercising its rights in international waters bring forward a crucial question: how do nations interpret and apply UNCLOS? Japan’s efforts to classify Okinotorishima as an island that bestows EEZ rights raise important considerations over how such classifications could reshape maritime boundaries and economic privileges. This is especially pertinent at a time when nations are increasingly relying on maritime resources for economic sustainability.
Broader Strategic and Regional Considerations
The Okinotorishima issue is only the tip of the iceberg in the broader maritime and territorial power play in the region. With China pursuing an aggressive maritime stance and advancing its claims over resource-rich waters across the Pacific and South China Sea, the stakes for regional players like Japan continue to grow exponentially. Coupled with Japan’s proximity to potential flashpoints, such as the Taiwan Strait, this dispute embodies the challenges posed by aligning historical claims and international law in a rapidly transforming geopolitical environment.
Navigating the Path Forward
The Okinotorishima debate underscores the critical need for continued dialogue and adherence to impartial international mechanisms to resolve disputes. As two of Asia’s leading economies, Japan and China share significant responsibilities in maintaining regional stability. Their ability to resolve such clashes diplomatically will have lasting implications not just for themselves but also for the maintenance of open international sea-lanes, resource management, and peace in the Indo-Pacific at large.
