The Nikkei Stock Average advanced 0.4% to 61683.96 in early trading, driven by strong gains in electronics shares that outweighed declines in the financial sector. Hitachi surged 3.3% and Kokusai Electric climbed 4.7%, providing the primary upward momentum for the benchmark index.

Conversely, financial stocks weighed on sentiment, with Nomura Holdings tumbling 6.7% and Mizuho Financial Group sliding 2.8%. The broader Topix index reflected this divergence, falling 0.6% to 3949.23, indicating that the rally was concentrated in specific sectors rather than broad-based.

In currency markets, the dollar traded at 163.26 yen, slightly weaker than the previous session's close of 163.55 yen. Market participants remain focused on a trio of key catalysts: corporate earnings reports, evolving geopolitical tensions in the Middle East, and fluctuations in crude oil prices, all of which could influence risk appetite and sector rotation in the near term.
