Recent Naval Movements
On April 22, 2026, a group of Chinese naval vessels, including a destroyer, passed through the Yonaguni-Iriomote Waterway, located between two islands administered by Japan's Okinawa prefecture. This transit followed the completion of training exercises in the Western Pacific by the People's Liberation Army's (PLA) Eastern Theater Command. The naval formation, designated as Vessel Formation 133, returned home after testing its far-seas capabilities. The Yonaguni-Iriomote Waterway, approximately 65 kilometers (35 nautical miles) wide, allows non-Japanese vessels to transit, although Japan retains the right to act if vessels enter its territorial sea, defined as extending 12 nautical miles (22 kilometers) from its shoreline.
Prior to this passage, the PLA formation had navigated through another waterway between the Japanese islands of Amami Oshima and Yokoate, which is situated northeast of the Yonaguni-Iriomote Waterway. This maneuver came shortly after a Japanese destroyer traversed the Taiwan Strait, an action that Beijing labeled a "deliberate provocation." China views Taiwan as part of its territory, despite Taiwan's assertion of independence.
Historical Context and Rising Tensions
Sino-Japanese relations have deteriorated significantly since November 2025, when Japanese Prime Minister Sanae Takaichi indicated that a hypothetical Chinese attack on Taiwan could prompt a military response from Japan. This statement has contributed to heightened military tensions in the region. The Chinese foreign ministry condemned Japan's naval activities, asserting that they threaten China's sovereignty and security. In response to Japan's military maneuvers, the Chinese defense ministry characterized the deployment of the Japanese destroyer as sending a "wrong" signal to pro-independence forces in Taiwan.
In September 2024, the Chinese aircraft carrier Liaoning's passage through the Yonaguni-Iriomote Waterway marked a significant escalation, as it was the first instance of a Chinese aircraft carrier entering Japan's contiguous waters, provoking strong protests from Tokyo.
Official Statements & Responses
The Chinese government has consistently criticized Japan's military activities in the region. Following the recent naval passage, a spokesperson for the Chinese foreign ministry reiterated that Japan's actions in the Taiwan Strait represent a "display of force" and a "deliberate provocation." In contrast, Japan's defense ministry has been advancing plans to deploy a medium-range surface-to-air missile unit at a military base on one of the islands, a move that China has labeled "extremely dangerous."
Criticism & Opposition
Critics of China's naval maneuvers argue that such actions exacerbate regional tensions and threaten the stability of East Asia. Japan's military buildup, particularly in response to perceived threats from China, has also drawn criticism for potentially escalating an arms race in the region.
Conflicting Reports & Gaps
There are discrepancies regarding the specific waterways used by the Chinese naval vessels during their recent transit. Initial reports incorrectly stated that the vessels passed through the Yonaguni-Iriomote Waterway, while later clarifications indicated they sailed through the Yokoate Waterway. This inconsistency highlights the complexities of maritime navigation and territorial claims in the region.
