日本首相或于8月底宣布退任，石破茂传达辞职意向

Core Viewpoint - Japanese Prime Minister Shigeru Ishiba intends to announce his resignation by the end of August following the poor performance of the ruling Liberal Democratic Party (LDP) in the recent Senate elections, which has led to significant political pressure within the party [1][4]. Group 1: Political Context - Ishiba's announcement comes after the LDP and its coalition partner Komeito lost their majority in the Senate, securing only 47 seats, below the 50 needed to maintain control, marking the first time in 70 years that the LDP has lost control of both houses [4][5]. - There is a growing call within the party for Ishiba to resign and restructure the party, with younger members urging for an early leadership election [4][5]. Group 2: Upcoming Decisions - The LDP leadership plans to hold a meeting on July 31 to discuss the election results, but this may be moved up to July 29 to expedite the process [5]. - Ishiba's resignation could lead to a prime ministerial election in the upcoming extraordinary Diet session next month, but the LDP's minority status raises uncertainty about the election outcome [5]. Group 3: Trade Agreements - A significant trade agreement was announced between the U.S. and Japan, where the U.S. will impose a 15% tariff on Japanese exports, and Japan will invest $550 billion in the U.S., with 90% of the profits going to the U.S. [6]. - Ishiba has indicated that he will review the details of this agreement before making further comments, but he believes it aligns with Japan's national interests [6].
