The Japanese financial market reached a historic milestone on Thursday as the benchmark Nikkei 225 breached the 62,000 level for the first time ever. Following the extended Golden Week holiday closure, investors returned aggressively to the market, pushing the index up more than 5% to close at 62,833.84.
The powerful rally was driven by a combination of surging global demand for AI-related semiconductor infrastructure and easing geopolitical tensions in the Middle East. Together, these catalysts created a broad risk-on environment across Asian equities.
SoftBank Emerges as a Major AI Market Proxy
SoftBank Group delivered the most dramatic move of the session, with shares soaring 18.44% in the company’s strongest single-day performance since 2020.
Market strategists increasingly view SoftBank as a listed proxy for the global AI ecosystem. Through its significant stake in Arm Holdings and its close ties to OpenAI, the company is positioned to benefit from accelerating investment in agentic AI systems and next-generation data center infrastructure.
The rally reflects growing investor confidence that AI infrastructure spending remains in the early stages of a long-term expansion cycle.
Japanese Semiconductor Stocks Jump on AI Demand
The broader semiconductor sector also posted sharp gains as Japanese traders reacted to record highs in the Nasdaq Composite after domestic markets reopened.
Several major companies in Japan’s chip supply chain recorded double-digit advances:
- Ibiden climbed more than 22%, making it the strongest performer of the day.
- Sumco Corp surged 19.74%.
- Renesas Electronics gained more than 13%.
- Tokyo Electron and Advantest rose 9% and 7%, respectively.
Both Tokyo Electron and Advantest continue to serve as highly liquid expressions of the AI semiconductor trade in Japan.
Industry analysts, including Rolf Bulk of The Futurum Group, note that datacenter CPUs have become a critical bottleneck in the global AI buildout. AMD recently projected a $120 billion addressable market for datacenter chips by 2030, reinforcing bullish sentiment toward Japanese semiconductor equipment suppliers.
Geopolitical Easing Supports Global Risk Appetite
While technology stocks provided the momentum, improving geopolitical conditions helped stabilize broader market sentiment.
Markets strengthened after President Donald Trump signaled a possible reduction in military tensions in the Middle East. According to recent communications, “Operation Epic Fury” could conclude if Tehran agrees to a diplomatic resolution.
Investors also reacted positively to signs that the U.S. naval blockade in the Gulf of Oman may end, helping ensure continued access through the Strait of Hormuz and easing concerns about disruptions to global trade flows.
The shift in sentiment influenced several major asset classes:
- WTI crude oil traded at $90.95 per barrel as markets assessed the potential for safer shipping routes and increased supply stability.
- Basic materials and financial stocks joined technology shares in driving the Nikkei higher, as cyclical sectors typically benefit from lower geopolitical risk.
Asian Markets Rally Alongside Japan
Japan’s breakout session lifted sentiment across the wider Asia-Pacific region.
As investors moved past earlier geopolitical concerns, equity markets across Asia closed firmly higher:
- South Korea’s Kospi rose 1.43% to 7,490.05.
- Hong Kong’s Hang Seng gained 1.57%.
- Australia’s S&P/ASX 200 advanced 0.96% to 8,878.1.
- Japan’s Topix index climbed 3% to close at 3,840.49.
The synchronized move highlighted renewed investor appetite for risk assets throughout the region.
Why the Nikkei 225 Break Above 62,000 Matters
The Nikkei’s climb to 62,833 represents more than a symbolic milestone. Analysts note that Japanese equities effectively priced in several sessions of global gains in a single trading day after reopening from the holiday break.
Billy Leung of Global X ETFs stated that while Japanese markets were closed, “global risk assets ripped,” forcing domestic equities to rapidly catch up with fresh highs in the S&P 500 and Nasdaq.
With AI infrastructure demand expanding at more than 35% annually and geopolitical rhetoric shifting toward diplomacy, investors increasingly view Japan as a central beneficiary of the global AI investment cycle.
For both traders and long-term investors, the combination of semiconductor leadership and SoftBank’s strategic exposure to AI has positioned Japan as a major pillar of the 2026 global bull market.
