Japan's Nikkei Slips as AI Stocks and China Trade Tensions Weigh

Published By DPRJ Universal | Published on Thursday, 8 January 2026

Japan's Nikkei share average fell for a second day, dropping 1.6%, due to profit-taking in AI stocks and escalating trade tensions with China. The market reacted to China launching an anti-dumping probe into Japanese chipmaking chemicals. SoftBank Group was a notable loser, with its shares sliding 7.6%, contributing significantly to the overall market decline.

Japan's Nikkei share average recorded its second consecutive day of losses, with the Nikkei 225 index dropping by a notable 1.6%. This downturn reflects a confluence of factors, primarily driven by investor sentiment shifting towards profit-taking in the high-performing artificial intelligence (AI) sector. After a period of robust growth, many AI-related stocks faced selling pressure as investors sought to lock in gains, thereby contributing to broader market weakness. Compounding these domestic pressures are escalating trade tensions between Japan and China, which have introduced significant geopolitical uncertainty into the market. The situation intensified following China's announcement of an anti-dumping probe into Japanese chipmaking chemicals. This investigative action is a critical development, suggesting potential punitive tariffs or restrictions on these essential components, which could severely impact Japanese manufacturers and global supply chains in the semiconductor industry. Such a move by China signals a tit-for-tat dynamic in trade relations, potentially leading to a broader economic fallout. Among the hardest hit was SoftBank Group, a major investment firm with significant holdings in technology and AI companies, whose shares plummeted by a substantial 7.6%. SoftBank's considerable drop highlights the market's sensitivity to both sector-specific corrections in tech and the broader implications of international trade disputes. The sustained decline in the Nikkei underscores a cautious market outlook, influenced by both internal market adjustments and external geopolitical challenges that continue to shape investor confidence.
