Japanese Prime Minister Shigeru Ishiba described the recently reached US-Japan trade deal as a "win-win" agreement benefiting both countries, emphasizing that implementation poses greater challenges than the negotiation itself. Ishiba highlighted the importance of swift action to put the deal into effect and expressed readiness to hold discussions with US President Donald Trump, either in person or by phone, to advance a 15% reduction in US auto tariffs. The Prime Minister also noted that the agreement does not need to be formalized in writing. Japan is prepared to compile an extra budget to mitigate the economic impact of US tariffs, a move that could strain the nation's finances. Implementation of subsidies under the deal depends on ongoing discussions with political parties, while private sector firms will make investment decisions, with a reported $550 billion US investment expected to benefit Japan. Trade negotiator Ryosei Akazawa, who is set to visit the US, stressed the need for prompt execution of the auto tariff order and criticized US trade tactics, describing the deal as an agreement between government agencies rather than a legally binding commitment. Akazawa also indicated that the US is attempting to alter global trade rules and norms. Ishiba underscored the critical need to limit the trade deal's impact on Japanese farmers and noted the deal's foundation on Japan's technology and US labor and market strengths. Finance Minister Katsunobu Kato reaffirmed efforts to maintain fiscal health and public confidence amid spending reforms. Additionally, Ishiba mentioned potential involvement of South Korea in US shipbuilding investments related to the deal and stressed the importance of monitoring trade deal implementation closely.
