**TOKYO — Japan’s industrial sector is showing one of its strongest bursts of confidence in years, powered by booming global demand for semiconductors, artificial intelligence infrastructure and the massive data centres needed to run the AI economy.**

Business confidence among major Japanese manufacturers climbed in September to its highest level since December 2021, according to the latest Reuters Tankan survey, adding another signal that one of Asia’s biggest industrial economies is benefiting from the worldwide AI investment race.

The Reuters Tankan manufacturing sentiment index rose to **+21 in September from +18 in August**, extending a dramatic recovery from just **+7 in April**.

A positive reading means more companies are optimistic than pessimistic about business conditions.

The survey, conducted from August 26 to September 4, received responses from **224 of 510 companies approached** and is closely followed because it can provide an early indication of trends that may later appear in the Bank of Japan’s official quarterly Tankan survey.

## Electronics Sector Leads the Charge

The biggest reason for the improving mood was unmistakable: technology.

Confidence among electronics manufacturers surged to **+39 from +24 a month earlier**, making the sector the standout performer in the September survey.

Japanese suppliers are benefiting from enormous investments in AI data centres, advanced chips, testing equipment, memory products and the components needed to build next-generation computing infrastructure.

Demand connected to data centres was described by one survey respondent as exceptionally strong, reflecting the ripple effect of global AI capital spending throughout Japan’s electronics supply chain.

The trend extends beyond the Reuters survey.

S&P Global reported in August that Japan's manufacturing sector had been expanding at some of its fastest rates in more than a decade, helped by stronger exports, improving orders and rising demand for technology products linked to the AI infrastructure build-out.

Japan's manufacturing exports in the S&P survey were growing at their strongest pace since 2018, while manufacturing output during the summer was running at rates not seen since 2014.

That makes the latest confidence reading more than an isolated sentiment spike. It is part of a broader improvement visible across orders, production and technology investment.

## Japan Is Becoming a Major Beneficiary of the AI Infrastructure Race

The numbers also highlight how deeply the global artificial intelligence boom is spreading beyond high-profile companies such as Nvidia and major cloud operators.

Japan is home to crucial semiconductor equipment manufacturers, electronic component suppliers, precision machinery companies and memory-chip producers.

One example is the planned expansion by **Kioxia Holdings and Sandisk**, which are preparing more than **¥5 trillion in investment over six years** to expand memory-chip production in Japan, according to Bloomberg reporting carried by The Japan Times.

The companies are responding to rapidly rising demand for storage technology needed by AI data centres.

The investment illustrates a much bigger economic shift: AI spending is increasingly flowing from software and computing giants into factories, chip plants, equipment makers, chemicals producers and industrial suppliers throughout Asia.

## Strength Is Spreading Beyond Electronics

Technology was not the only bright spot in the Reuters Tankan.

Precision machinery sentiment remained strong at **+29**, while the metal-products index edged higher to **+26**.

Textiles, paper and pulp also improved sharply, moving to **+13 from zero**.

Not every industry joined the rally, however. Steel and nonferrous metals remained weak at **\-13**, showing that Japan’s industrial recovery remains uneven.

Confidence among large non-manufacturing companies also improved slightly, with the index moving to **+29 from +28**.

Real estate and construction sentiment climbed to +37, while transportation and utilities strengthened to +33.

Retailers also became more optimistic, although information and communications companies reported weaker sentiment than in August.

## Businesses Think Things Could Get Even Better

Perhaps one of the most important signals in the survey is what manufacturers expect next.

Looking three months ahead, manufacturers forecast their confidence index rising further to **+27**.

That suggests companies do not currently view the semiconductor and AI-driven surge as merely a temporary spike.

But several risks could interrupt that momentum.

Companies participating in the survey identified **higher raw-material costs, geopolitical tensions in the Middle East and weakness in Japanese consumer spending** as significant threats.

That last issue is particularly important.

Japanese household spending fell **3.6% year-on-year in July**, the steepest decline in roughly two-and-a-half years and the eighth consecutive annual decrease, according to government data reported by Reuters.

Consumers have continued to face pressure from higher living costs even as wages improve.

## Japan's Economy Is Growing — But Consumers Remain Cautious

Japan's broader economic numbers nevertheless point toward resilience.

Revised government figures showed the economy expanded at an annualised **1.4% rate during the April-June quarter**, slightly stronger than the preliminary estimate of 1.1%.

External demand supported growth, while domestic demand remained comparatively soft.

Meanwhile, Japanese workers received another significant boost.

Nominal wages increased **4.7% from a year earlier in July**, the fastest gain since 1997, according to Bloomberg reporting published by The Japan Times.

Inflation-adjusted real wages rose **2.4%**, their biggest increase in about five years.

Those numbers could eventually translate into stronger consumer spending—but they also create another consequence for businesses.

## The Bank of Japan Is the Next Big Test

Stronger wages, resilient economic growth and improving corporate confidence are strengthening the case for another Bank of Japan interest-rate increase.

Markets are heavily positioned for the BOJ to raise its policy rate by **25 basis points to 1.25% at its September 17-18 meeting**, after the central bank lifted its rate to 1% in June.

A move to 1.25% would continue Japan's gradual departure from the ultra-low borrowing costs that defined the country's economy for decades.

That creates an unusual balancing act.

Higher rates could help control inflation and support the yen, but they also increase financing costs for companies, property developers and households.

The yen has already strengthened sharply ahead of the BOJ meeting, recently reaching its highest level in roughly seven months against the US dollar.

A stronger yen reduces the cost of imported energy and raw materials but can hurt Japanese exporters by reducing the yen value of overseas earnings.

## The Bigger Story: AI Is Reaching the Real Economy

Japan's September confidence numbers reveal something bigger than improving factory sentiment.

The artificial intelligence boom is moving deeper into the physical economy.

AI systems require enormous amounts of memory, semiconductors, servers, networking equipment, power infrastructure, cooling systems and specialised manufacturing machinery.

Japanese companies occupy important positions across many of those supply chains.

For now, the result is visible in a manufacturing confidence reading not seen since 2021.

The question is whether semiconductor and data-centre demand will remain powerful enough to overcome rising interest rates, expensive raw materials, geopolitical instability and cautious Japanese consumers.

If it does, Japan could emerge as one of the biggest industrial beneficiaries of the global AI investment cycle.

And with manufacturers already predicting even stronger conditions three months from now, **the most important number may not be September’s near-five-year high—but how much higher confidence can climb before those economic headwinds finally catch up.**
