关税协议，美日存在认知落差，日本不敢明言，外媒：怕美国翻脸

Core Viewpoint - The relationship between the United States and Japan is characterized by inequality, with recent U.S. tariff actions against Japan highlighting this dynamic, especially during Japan's Senate elections [1]. Group 1: U.S.-Japan Tariff Negotiations - The U.S. unexpectedly announced a 25% tariff on Japan just before the Japanese Senate elections, which could significantly impact the support for Japan's ruling party [1]. - Following a final ultimatum from the U.S., the two countries held an eighth round of negotiations, resulting in a superficial agreement where the U.S. claimed a 15% tariff concession from Japan, but discrepancies in understanding the agreement's details remain [3]. - The U.S. has threatened to restore the 25% tariff if Japan's concessions do not meet expectations, indicating Japan's fear of U.S. retaliation [5]. Group 2: Military and Economic Implications - The U.S. claims Japan has committed to purchasing more military equipment, but Japan lacks the necessary budget to fulfill this commitment in the short term [5]. - The U.S. also announced that Japan would buy 100 American aircraft, a claim that appears to exaggerate Japan's concessions as these purchases were already planned by Japanese airlines [6]. - Overall, the U.S. is perceived to be using tactics to create a narrative of victory in trade negotiations, while the actual benefits may ultimately fall on American consumers [6].
