Group 1 - The core viewpoint of the article is that Japanese Prime Minister Sanna Marin and U.S. President Trump are set to enhance the Japan-U.S. alliance during their upcoming meeting, focusing on security and economic issues [3][5]. - The meeting is expected to address the "investment for tariff" agreement, which involves the U.S. imposing a 15% tariff on Japanese goods, while Japan commits to establishing a $550 billion investment tool for the U.S., representing nearly 10% of Japan's annual GDP [7][8]. - High City is preparing a "welcome gift" for Trump, including purchases of Ford F-150 trucks, soybeans, and liquefied natural gas from the U.S. [7]. Group 2 - High City is not expected to commit to new defense spending targets during the meeting, despite previously stating a goal of achieving 2% of GDP for annual military spending, which falls short of the U.S. request for 3.5% [8]. - The joint travel on the Marine One helicopter signifies a strong Japan-U.S. alliance, with the Yokosuka base being a strategic location for U.S. military operations in the region [11]. - Analysts suggest that High City may position herself as a "reliable partner" for the U.S., but there are concerns that the Japan-U.S. alliance could become less reliable and effective due to the influence of right-wing populist parties in Japan [12].
