對日本實行分區(qū)占領系第二次世界大戰(zhàn)的勝利成果之一且由《波茨坦公告》（實為《開羅宣言》的升級版）明確界定的，簡言之，中國、美國、蘇聯(lián)、英國都有權駐軍日本。針對中國駐軍日本的具體事宜安排，則是由《中國駐日占領軍備忘錄》進行明確。《中國駐日占領軍備忘錄》的法律基礎來源于《波茨坦公告》第七條之規(guī)定“日本領土經盟國之指定，必須占領”；中國作為盟國成員之一，具有駐軍日本的權力。本條款就為中國作為戰(zhàn)勝國在日本駐軍提供了無可辯駁的法律依據。

1946年07月20日，中美雙方簽署《中國駐日占領軍備忘錄》規(guī)定，中國駐日占領軍區(qū)域為愛知縣，師部設在名古屋；在必要時，駐軍范圍還可以擴展至三重縣、靜岡縣。當然，中國駐日占領軍要接受盟軍最高統(tǒng)帥部的領導并聽從其指揮。中國駐日占領軍區(qū)域主要位于四國島，該區(qū)域覆蓋了日本東京和中部工業(yè)區(qū)的核心地帶，具有極其重要的監(jiān)控工業(yè)和戰(zhàn)略防控價值。有關該備忘錄的效力和“效期”問題，也明確規(guī)定，中國或美國任何一方都無權單方廢止，“除非中美雙方共同宣布廢止，否則協(xié)議持續(xù)有效”。因此、該備忘錄直到如今仍有法律效力。

必須要說明的是：其一、代表中國簽字的系當時的中華民國政府，現(xiàn)在的合法權力和權利已經歸屬中華人民共和國（聯(lián)合國方面已經確認）；其二、雖然蘇聯(lián)已經解體了，但是代表蘇聯(lián)合法權力和權利是如今的俄羅斯聯(lián)邦。換而言之，今天的中國和俄羅斯都有權駐軍日本。這就是真正的懸在日本頭上的“達摩克里斯之劍”，在必要的時候，我們也好，俄羅斯也罷，都可以重啟對日本的駐軍權或者喚醒這些條款對日本的駐軍權利（好像這些權利條款沒有完全實施，日本政府方面還真當這些條款“沉睡”了呢）；因此，這是我們的一張很重要的牌。

The 10th Episode of “Global Refuel”: According to the Potsdam Proclamation and the Memorandum on Chinese Occupation Forces in Japan, We Still Have the Right to Station Troops in Japan

(Thursday Afternoon, December 18, 2025)

The partition occupation of Japan was one of the victorious outcomes of World War II and was clearly defined by the Potsdam Proclamation (essentially an upgraded version of the Cairo Declaration). In short, China, the United States, the Soviet Union, and the United Kingdom all had the right to station troops in Japan. The specific arrangements regarding the stationing of Chinese troops in Japan were clarified in the Memorandum on Chinese Occupation Forces in Japan. The legal basis for this Memorandum derives from Article 7 of the Potsdam Proclamation, which stipulates that "Japanese territory shall be occupied as the Allies may designate." As one of the Allied nations, China possesses the right to station troops in Japan. This provision provides an indisputable legal basis for China, as a victorious nation, to station troops in Japan.

On July 20, 1946, China and the United States signed the Memorandum on Chinese Occupation Forces in Japan, stipulating that the Chinese occupation zone in Japan would be Aichi Prefecture, with the divisional headquarters located in Nagoya. If necessary, the area of occupation could be extended to include Mie and Shizuoka Prefectures. Of course, the Chinese occupation forces were to be under the leadership and command of the Supreme Commander for the Allied Powers. The Chinese occupation zone was primarily located on Shikoku Island, an area covering the core regions of Japan's Tokyo and central industrial zones, holding significant monitoring and strategic control value regarding industry. Regarding the validity and "duration" of this Memorandum, it was explicitly stated that neither China nor the United States had the right to unilaterally abrogate it; "unless both China and the United States jointly declare its abrogation, the agreement shall remain in effect." Therefore, this Memorandum retains legal force to this day.

It must be clarified: First, the signatory on behalf of China was the then Republic of China government, whose legitimate powers and rights have now been succeeded by the People's Republic of China (as confirmed by the United Nations). Second, although the Soviet Union has dissolved, its legitimate powers and rights are now held by the Russian Federation. In other words, both China and Russia today have the right to station troops in Japan. This is the true "Sword of Damocles" hanging over Japan. When necessary, we, as well as Russia, can reactivate the right to station troops in Japan or "awaken" these provisions concerning the right to station troops in Japan (it seems these rights were not fully implemented, and the Japanese government has truly acted as if these provisions are "dormant"). Therefore, this is a very important card in our hand.
