Just 8 days before the Japanese national election took place, on October 23, 2021, the Chinese and Russian naval vessels crossed the Osumi Strait. In effect, the 5 Chinese and 5 Russian naval vessels circumnavigated the island of Japan, starting from the Tsugaru Strait and ending in Osumi Strait. The annual provocation from the Chinese and Russian naval vessels against Japan has surpassed previous levels of provocation, reaching new heights this year. According to the Joint Staff of the Japan Self Defense Force, 5 Chinese ships and 5 Russian ships were identified. They have identified the Chinese ships as Type 055 destroyer Nanchang (101), Type 052D destroyer Kunming (172), Type 054a frigates Binzou (515) and Liuzhou (573), and an unnamed replenishment ship (902), while they have identified the Russian ships as the destroyers Admiral Tributs(564) and Admiral Panteleyev (548), corvettes Gromkiy (335) and Hero of the Russian Federation Aldar Tsydenzhapov (339) and the missile range instrumentation ship Marshal Krylov (331). According to the internationally recognized policy for identifying territorial waters, territorial waters are said to be 12 nautical miles from each shore. However, the Japanese government had identified these straits as territorial waters only up to 3 nautical miles from each shore, in order to accommodate their “Three Non-Nuclear Principles.” The result of identifying only 3 nautical miles is the identification of the central area of these Japanese straits as international waters, which allows for foreign vessels to sail through the straits with no authorization from the Japanese government. In addition to sailing through two Japanese straits, a Chinese helicopter was captured lifting off, which caused the Japanese Air Force to scramble a jet fighter to counteract the aerial threat. The Japanese Minister of Defense Nobuo Kishi made a remark on October 26, 2021, that there must be greater vigilance going forward to maintain the security of Japan.
