**Japan’s Nikkei Surges as AI Boom Sparks Investor Optimism**

**Introduction**
Tokyo’s benchmark Nikkei 225 jumped more than 2% in early trading on Wednesday, extending a rally that has lifted the index to its highest level in over a year. The surge follows a wave of upbeat earnings reports from Japanese technology firms and fresh optimism about the country’s role in the global artificial intelligence (AI) supply chain.

However, some analysts caution that the rally may be overextended if macro‑economic headwinds—such as weakening export demand and a stubbornly high yen—persist. They point to the Bank of Japan’s recent decision to maintain ultra‑low interest rates as a double‑edged sword: while cheap financing supports corporate investment, it also fuels concerns about asset bubbles in high‑growth stocks.
