The Nikkei 225 edged up 0.06% to close at 39,811, while the broader Topix slipped 0.04% to 2,828 on Friday, with both indexes ending the session virtually flat as renewed concerns over US tariff policy dampened investor sentiment. Market caution intensified after President Donald Trump announced plans to begin issuing letters on trade matters, potentially setting unilateral tariff rates. Trump has previously threatened to raise tariffs on Japanese goods by up to 35%, citing dissatisfaction with Japan’s limited imports of American rice and automobiles. On the domestic front, household spending in Japan rose 4.7% year-over-year in May, rebounding sharply and exceeding expectations, as Tokyo ramped up efforts to boost consumption. Trading was mixed, with notable gains from Advantest (+1.4%) and Mitsubishi UFJ (+1.5%), while Disco (-2.2%) and Fujikura (-2.4%) led losses. For the week, the Nikkei declined 0.85% and the Topix fell 0.44%.
