Japan’s market is no longer running on a single engine. It is being driven by three powerful themes at the same time: semiconductors, electricity demand and real estate. But the latest session reveals an important difference between headline index strength and the actual breadth of the market.

The Nikkei 225 closed at 65,018.95, up 882.75 points or 1.38%, extending its winning streak to three sessions. Over 12 months, the index is up around 44.34%, while the one-month performance remains slightly negative at -0.47%. The Topix, however, tells a different story. It remains only around 2% below its record close of 4,176.04, showing that Japan’s broader market is behaving differently from the technology-heavy Nikkei.

The key point is index concentration. The Nikkei is price-weighted, and technology-related companies represented roughly 56.8% of its weight in early September. Tokyo Electron, Advantest, SoftBank, Ibiden and Kioxia together create significant semiconductor exposure. That means a strong chip session can lift the Nikkei dramatically even when broader participation is much less impressive. On 18 September, the Nikkei gained 1.38%, while the Topix was broadly flat. For traders, that divergence matters: headline strength does not automatically mean broad market strength.

SEMICONDUCTORS: THE MAIN ENGINE
Semiconductors remain the strongest visible growth engine. On 18 September, Tokyo Electron, Advantest, Lasertec and Kioxia advanced roughly 4%–9%, supported by renewed strength across the global AI and semiconductor complex.
Tokyo Electron traded around ¥53,110, gaining approximately 4.20% on the session, and has risen roughly 107% over 12 months, although its one-month performance remains around -2.84%. That combination shows both extraordinary long-term momentum and meaningful short-term consolidation.
Valuation is now becoming increasingly important. Tokyo Electron trades around 28x forward earnings, Advantest around 40.7x, Disco around 37.5x, Renesas around 15.5x, while Kioxia remains much cheaper on the cited valuation screen at roughly 5.3x after an enormous year-to-date advance.
This creates two very different semiconductor trades. The equipment leaders offer powerful exposure to AI and advanced-node capital expenditure, but expectations are already elevated. Kioxia represents a different part of the memory cycle, where supply constraints and pricing power can create substantial earnings leverage.
Japan’s government is reinforcing the theme. METI has allocated approximately ¥1.23 trillion toward semiconductors and AI in FY2026, while Rapidus is targeting advanced-node production and TSMC’s Kumamoto expansion strengthens Japan’s domestic semiconductor ecosystem.
The bullish structural story is therefore clear: AI investment increases demand for advanced chips, advanced chips require equipment, and Japan remains a critical supplier of semiconductor manufacturing technology.
But this is also the biggest concentration risk. After a roughly 100% one-year move in some equipment names, earnings growth must continue to justify increasingly demanding valuations.

POWER: AI’S SECOND-DERIVATIVE TRADE
Electricity is becoming the second major part of Japan’s AI story.
Japan’s data-centre electricity consumption is projected to rise from around 19 TWh in 2024 to approximately 57–66 TWh by 2034, potentially making data centres responsible for around 60% of total power-demand growth. Peak demand from data centres could reach roughly 6.6–7.7 GW.
This changes the investment case for utilities. The opportunity is not simply higher electricity consumption. It also includes nuclear restarts, fuel-cost savings, grid investment and stronger pricing dynamics.
The sector, however, is highly differentiated.
Chubu Electric is up around 41.61% over 12 months, while Kansai Electric has gained approximately 33.71%. TEPCO is very different, remaining around -19.82% over 12 months despite a recent +9.50% one-month recovery.
That divergence matters.
Kansai, Chubu and Kyushu can be viewed primarily through the lens of earnings, nuclear restarts and electricity demand. TEPCO remains much more dependent on balance-sheet repair, nuclear developments and the long-term consequences of its restructuring.
The nuclear story is becoming increasingly relevant. TEPCO’s Kashiwazaki-Kariwa Unit 6, with capacity of around 1,315 MW, restarted in January 2026 and entered commercial operation in April. Japan has now restarted multiple reactors since 2011 and continues to target nuclear power at roughly 20%–22% of generation by 2030.
For the market, nuclear restarts can reduce LNG dependence and improve generation economics, while rising data-centre demand provides a structural source of electricity consumption.
But there is a short-term counterforce: higher interest rates.
On the BOJ decision day, Chubu Electric fell around 1.77% and Kansai Electric declined approximately 2.48%. This demonstrates that the power trade is not immune to monetary tightening. Higher JGB yields can pressure valuation multiples even when the long-term electricity-demand thesis remains intact.

REAL ESTATE: THE QUIETER REFLATION TRADE
Real estate is receiving less attention than chips, but the underlying operating numbers are important.
Tokyo’s central five wards recorded office vacancy around 2.20%, while average rent reached approximately ¥22,454 per tsubo, around 8% higher year-on-year based on the cited data.
Mitsubishi Estate reported exceptionally low vacancy in Marunouchi, while Mitsui Fudosan has continued to see improvement in office and retail occupancy. Management commentary around higher rents and redevelopment provides another potential earnings driver.
Yet the share-price performance is much less aggressive than semiconductors.
Mitsui Fudosan has been around -7.71% over 12 months, despite gaining roughly 2.63% over the past month. Mitsubishi Estate traded around ¥3,606, while Tokyo Tatemono was around ¥3,281.
This creates an interesting divergence between operating fundamentals and market valuation.
Mitsui Fudosan reported approximately ¥2.63 trillion revenue and ¥372.7 billion operating profit, while Mitsubishi Estate reported around ¥1.58 trillion revenue and ¥309.2 billion operating profit. Both companies have also announced major share-buyback programmes.
The real-estate thesis therefore depends on two opposing forces.
Higher rents, low vacancy, rising land prices, redevelopment and buybacks support earnings and shareholder returns.
Higher interest rates and rising JGB yields increase financing costs and can put pressure on property valuations.
That makes Japanese real estate a reflation-versus-rates trade rather than a simple property boom.

LIQUIDITY: THE MARKET HAS PLENTY OF FUEL
Liquidity is not currently the obvious constraint.
TSE Prime turnover averaged approximately ¥8.57 trillion per day during the week of 7–11 September, with around 2.19 billion shares changing hands. The week of 10–14 August recorded average turnover of roughly ¥9.74 trillion, while the 1 September session reached approximately ¥9.36 trillion on 2.67 billion shares.
Foreign investors are also important. Net foreign purchases of Japanese equities reached approximately ¥9.7 trillion in the first half of 2026, according to the cited data, representing an exceptionally strong inflow.
But flows remain volatile. A large weekly inflow can quickly be followed by significant selling. That means liquidity is supporting the market, but it does not eliminate downside risk.

THE MOST IMPORTANT SIGNAL: ROTATION
The strongest takeaway is not simply that Japan is bullish or bearish.
It is that capital is rotating between different expressions of the same macro theme.
When technology and semiconductor shares weaken, money can move toward utilities, banks, real estate or other domestic beneficiaries. When global AI sentiment strengthens, semiconductor equipment can once again dominate the Nikkei.
This explains why the Nikkei can move sharply even when the broader Topix is much quieter.
The market is therefore increasingly becoming a battle between AI growth, electricity demand, domestic reflation and higher interest rates.
WHAT COULD DRIVE THE NEXT MOVE?
For semiconductors, the key variables are US AI capital expenditure, global chip demand, memory pricing and Japanese equipment orders.
For utilities, watch nuclear restarts, electricity demand from data centres, LNG prices and regulatory developments.
For real estate, Tokyo rents, vacancy rates, land prices, redevelopment activity and long-term JGB yields are critical.
For the entire Japanese market, the biggest macro variables remain the BOJ rate path, the yen, JGB yields and foreign equity flows.
The yen around ¥156 per dollar remains particularly important. A weaker yen can support exporters and overseas earnings translation, but it also increases imported energy and commodity costs. Any further currency intervention risk could increase volatility across Japanese assets.

MY MARKET READ
Japan’s rally has real fundamental support, but the composition of the rally matters more than the headline index.
Chips are the high-growth engine. Power is the AI-infrastructure and nuclear-restart engine. Real estate is the domestic reflation and rental-growth engine.
The semiconductor story currently has the strongest momentum, but it also carries the highest valuation and concentration risk.
The power story has a long-term structural catalyst from data centres, electrification and nuclear restarts, but higher interest rates can create short-term pressure.
Real estate has improving rents, low vacancy and shareholder-return catalysts, but rising JGB yields remain a major valuation risk.
The most important chart to watch is therefore not just the Nikkei.
Watch Nikkei vs Topix breadth, semiconductor leadership vs utilities, 10-year JGB yields, USD/JPY and foreign equity flows.
If chip leadership continues while the Topix breadth improves, the rally would be supported by a broader participation base. If the Nikkei keeps rising primarily because a small group of semiconductor names is accelerating, concentration risk becomes increasingly important.
Japan’s market is no longer simply a story about equities going higher. It is becoming a contest between AI demand, power infrastructure, reflation, property earnings and the BOJ’s tightening cycle.
