Japan’s industrial production rose 2.2% in September from August, the first monthly gain in three months, as car plants recovered from earthquake-related shutdowns, the Ministry of Economy, Trade and Industry (METI) said in its preliminary report released Friday, Oct. 30. Data published the same morning showed the jobless rate edging down to 2.4% while retail sales slipped on the month.

The production index for mining and manufacturing reached 104.1 (2020 = 100, seasonally adjusted). The rise beat the 1.3% median forecast in a Reuters poll of private economists, Reuters reported (in Japanese). METI left its overall assessment unchanged, describing production as one that “fluctuates indecisively.”

Car plants lead the September rebound

Motor vehicles contributed the most to the increase, followed by production machinery and general-purpose and business-oriented machinery, according to METI. Auto output rose 5.5% from August and added about 0.69 percentage point to the index, Reuters said. A METI official told the news agency that production of standard passenger cars, which had fallen because of the Kumamoto earthquake, had recovered. Output of semiconductor manufacturing equipment and conveyors also increased.

Not every sector grew. Iron, steel and non-ferrous metals made the largest negative contribution, followed by ceramics, stone and clay products and by chemicals, METI said. Shipments rose a smaller 0.6% on the month, and the original (not seasonally adjusted) production index stood 1.9% above September 2025.

The rebound follows a weak summer. The index fell 0.2% in July and 2.4% in August, when it dropped to 101.9, according to METI figures. September’s level is roughly back to where it stood in June and July, rather than at a new high.

By the numbers: production, jobs and stores

Read together, Friday’s releases show factories recovering faster than consumers are spending. Some TBR calculations from METI’s index series make the pattern clearer:

• September’s 104.1 is 3.1% above the 101.0 reading of September 2025 on the seasonally adjusted series, but 0.5 point below June’s 104.6, the highest month in the past year.
• Of the 12 monthly changes from October 2025 through September 2026, seven were increases and five were declines, which fits METI’s “indecisive” label.
• If manufacturers deliver the 5.1% October increase and 0.8% November increase they told METI they plan, the index would rise to about 109.4 and then about 110.3. These are TBR calculations that apply the survey percentages to September’s level; such plans are often revised.

Factories plan bigger gains, but inventories are rising

Manufacturers surveyed by METI expect output to climb 5.1% in October, led by electronic parts and devices, production machinery and electrical and information and communication equipment. In November, they expect a further 0.8% gain driven by transport equipment and general-purpose machinery. In the September survey, the same companies had projected a 3.1% rise for October.

Stockpiles are the caution flag. The inventory index rose 2.5% in September, its first increase in two months, with 12 of 15 industries posting gains, Reuters reported. Inventories had trended down since 2023 before climbing 2.8% in June and again slightly in July. A senior METI official told Reuters inventories “have recently been on an upward trend and need watching” (translated from Japanese). The inventory ratio, which compares stock with shipments, rose 2.0%.

Labor market tightens slightly

The seasonally adjusted unemployment rate fell 0.1 point to 2.4% in September, the Statistics Bureau of Japan’s Labour Force Survey showed. Employment totaled 68.96 million people, 330,000 more than a year earlier and the second straight annual increase. The number of unemployed people, 1.69 million, was 150,000 lower than a year before.

The ratio of job openings to applicants rose 0.01 point to 1.19, the Ministry of Health, Labour and Welfare (MHLW) said, meaning there were 119 openings for every 100 job seekers at public employment offices. The ratio for new openings climbed 0.13 point to 2.19. Applicant numbers fell 1.4% on the month, and an MHLW official told Nikkei that heavy rain and other bad weather may have kept some job seekers from visiting Hello Work offices in September.

New job offers in manufacturing were 8.2% higher than a year earlier, the biggest increase among major industries, MHLW data show. Nikkei said hiring for semiconductor-related work such as electronic-device manufacturing stood out, which lines up with the chip-equipment strength in METI’s production report.

Shoppers pull back on the month

Retail sales came to 12.873 trillion yen in September, 2.3% more than a year earlier, according to METI’s preliminary commerce survey. Adjusted for seasonal swings, though, sales fell 0.7% from August. By store type, auto dealers posted a 15.6% year-over-year increase, while machinery and appliance retailers fell 5.7% and fuel retailers fell 3.0%.

The weaker consumer picture comes as the Bank of Japan weighs how fast to raise borrowing costs. The central bank held its policy rate at 1.25% this week, as The Boston Report covered on Oct. 30. Separately, core consumer prices in Tokyo’s 23 wards rose 2.6% in October from a year earlier, down from 2.7% in September, The Japan Times reported.

What it means for the U.S.

Japan’s car and chip-equipment makers ship heavily to American buyers and also run large factories in the U.S., so swings in their home output feed into supply chains on both sides of the Pacific. For a comparison with Japan’s largest neighbor, see our report on China’s October factory PMI, which showed contraction.
