Japan’s manufacturing sector expanded at the fastest pace in more than eight years in August, with the S&P Global Flash Japan Manufacturing Purchasing Managers’ Index rising to 55.1 from 54.5 in July, according to data released Friday. The 50.0 threshold separates growth from contraction, and the latest reading marks the second consecutive month of acceleration in factory activity.
New orders grew at the quickest rate since January 2018, driven by strong demand from semiconductor and artificial intelligence-related industries. Overseas demand also posted its steepest increase in over eight and a half years, signaling broadening participation in the expansion. Total sales followed a similar trend, reinforcing indications of broad-based momentum in the industrial sector.
The broader private economy showed further signs of stabilization. The S&P Global Flash Japan Services PMI Business Activity Index climbed to 52.3 from 51.2 in July, while the Composite Output Index—a measure of combined manufacturing and services activity—rose to 53.4, the highest since February. The data suggests that despite a softer second-quarter GDP print, underlying momentum in the economy remains intact.
Cost pressures continued to ease from recent highs. Overall input inflation across the private sector slowed to a five-month low, though selling prices for goods and services remained elevated by historical standards. Business confidence improved to its strongest level since February, with manufacturers expressing greater optimism than service providers, citing expectations of higher sales, expanded capacity, and firmer market conditions.
Manufacturers led employment growth in August, increasing input purchases and experiencing only a modest rise in stock accumulation. Supplier delivery times lengthened markedly, reflecting capacity constraints in supply chains. S&P Global Market Intelligence’s Annabel Fiddes noted that factory output and new orders accelerated sharply, adding to evidence that Japan’s private sector is well-positioned for sustained growth, provided price and demand shocks remain absent.
The August PMI figures, published by S&P Global on August 21, follow a July GDP report that showed economic deceleration, though analysts largely attributed the soft reading to temporary factors rather than a sustained slowdown in momentum.
