近年來，日本以“周邊安全環境日益惡化”為由加速軍事擴張，而多項動作被外界普遍視為直指中國。最新曝光的資訊顯示，日本的“戰爭準備”正以前所未有的速度與範圍全面鋪開，從法律、科技、軍事部署到基礎設施改造，幾乎每個層面都被納入潛在戰時框架，甚至精細到“戰俘如何處理”這類高度敏感的規劃。

日本政府被曝正在制定一套更具體的戰時法律，內容不僅涉及自衛隊的動員方式、民間資源徵用與運輸管制，更首次細化到若爆發武裝衝突時，如何管理、拘押並處置敵方戰俘。這類規劃的曝光在國際間引發震動，因為它暗示日本並非只在做防禦性準備，而是正式將“實際軍事衝突”納入決策架構。外界評論普遍認為，日本此舉是為了補足其自稱“反擊能力”的法律空白，而其假想對手在官方與半官方語境中越來越明確地指向中國。

在軍事科技方面，日本開始投入研發“萬能型血漿”，即不受血型限制即可輸用的軍用血液替代品。這類產品過去主要由美軍推動，用於大型戰爭或遠距離的高強度作戰環境，以提高戰場救治效率。日方的研究明顯具有軍事導向，顯示其戰時醫療後勤已提前布局。

基礎設施方面，日本正在大規模改造多處民用港口，使其具備軍民兩用能力。按官方說法，這將有助於在“重大危機時”提升補給效率，但多名專家指出，這實際上是為了快速轉換為軍艦、後勤艦與美軍支援部隊提供靠泊與補給，尤其是在南西諸島鏈等靠近中國的敏感區域。這些民用港口一旦 militarized，其角色將不再單純，而是成為第一島鏈的重要軍事節點。

與此同時，日本正將多個接近中國的島嶼打造成“前線”。沖繩、宮古島、石垣島、與那國島等地區陸續部署反艦飛彈、遠程雷達與電子作戰設備，被視為環繞中國的“火力網”的一部分。日本也在與美軍合作擴大F-35戰機基地與大型彈藥庫的建設範圍，以容納更多美軍戰機、巡弋飛彈及精準打擊武器。這些部署被指意在封鎖南海—台海—第一島鏈的重要戰略航道，使其具備在衝突初期就能阻斷中國軍艦與補給路線的能力。

外界普遍關注，日本此類軍事動作已從“防衛”逐漸轉向“預置衝突”模式。不僅是自衛隊，美國亦深度參與相關規劃，強化日美軍事一體化。日本國內媒體分析指出，這是一場實質上的軍備重整，日本正試圖全面突破其戰後體制。多項準備工作的方向與規模，都讓觀察者擔憂東亞安全局勢正滑向更具危險性的狀態。

整體而言，日本的行動已遠超一般國家為維持安全所做的常規準備，而更像是一套完整、具體、甚至邁向可執行階段的“戰時工程”。這些舉措因其針對性極強，在國際間引發廣泛議論，也使中日關係的緊張情勢進一步升溫。

In recent years, citing an “increasingly deteriorating regional security environment,” Japan has accelerated its military expansion, with multiple actions widely seen as directed at China. Newly revealed information indicates that Japan’s “war preparations” are being rolled out at an unprecedented pace and scope. From legal frameworks and technological development to military deployment and infrastructure modification, nearly every aspect is being incorporated into a potential wartime framework, even including detailed plans for the treatment of prisoners of war.

Reports show that the Japanese government is drafting a set of more specific wartime laws. These laws cover not only the mobilization of the Self-Defense Forces, the requisitioning of civilian resources, and transportation controls, but also, for the first time, detailed procedures for managing, detaining, and handling enemy POWs in the event of armed conflict. The exposure of these plans has caused international concern, as it suggests that Japan is not merely preparing defensively but is formally incorporating the possibility of actual military conflict into its decision-making. Observers generally believe that these measures aim to address legal gaps in Japan’s so-called “counterattack capability,” with China increasingly perceived as the potential adversary in official and semi-official contexts.

On the military technology front, Japan has begun developing a “universal plasma” capable of being used regardless of blood type. Such products were previously promoted primarily by the U.S. military for large-scale wars or high-intensity, long-distance combat situations to improve battlefield medical efficiency. Japan’s research clearly has a military orientation, indicating that wartime medical logistics are being planned well in advance.

In terms of infrastructure, Japan is undertaking large-scale modifications of several civilian ports to make them dual-use for both civilian and military purposes. Officially, this is said to enhance supply efficiency during “major crises,” but experts note that it effectively allows rapid deployment of warships, logistics vessels, and U.S. military support, especially in the sensitive areas along the southwestern island chain near China. Once militarized, these civilian ports would serve as critical nodes in Japan’s first island chain strategy.

Meanwhile, Japan is transforming multiple islands close to China into “frontline outposts.” Okinawa, Miyako, Ishigaki, and Yonaguni islands are being equipped with anti-ship missiles, long-range radar, and electronic warfare systems, forming part of a so-called “firepower network” encircling China. Japan is also expanding F-35 bases and large-scale ammunition depots in cooperation with the U.S., accommodating more U.S. aircraft, cruise missiles, and precision-strike weapons. These deployments are viewed as a strategy to block key strategic shipping lanes in the South China Sea and Taiwan Strait at the outset of a conflict, potentially disrupting Chinese naval and supply routes.

Observers note that Japan’s military moves have gradually shifted from “defense” toward a “preemptive conflict posture.” Not only is the Japanese Self-Defense Force involved, but the U.S. is also deeply integrated into planning, strengthening Japan-U.S. military integration. Domestic Japanese media analyses suggest that this represents a substantial military reorganization, with Japan attempting to break through post-war constraints. The scale and specificity of these preparations have raised concerns that East Asian security is moving toward a more perilous state.

Overall, Japan’s actions go far beyond routine defensive preparations, resembling a comprehensive, concrete, and operationally oriented “wartime engineering” program. Due to their highly targeted nature, these measures have sparked broad international debate and further heightened tensions in China-Japan relations.
