The S&P Global Japan Manufacturing Purchasing Managers' Index (PMI) registered 53.3 in October, slipping from 54.1 in September and marking the weakest expansion reading in seven months. A PMI reading above the 50‑point threshold still signals overall sector growth, but the slowdown reflects a deceleration in activity. Production continued to rise for a tenth consecutive month, yet the growth rate was the slowest since March, indicating a cooling of output momentum. New orders also increased for a tenth straight month, but the pace of order growth was the slowest observed in the past seven months. Input price inflation accelerated during October, while output charge inflation declined to a six‑month low, highlighting divergent cost pressures within the sector. In response to rising input costs, manufacturers expanded their inventory purchases at the fastest rate in nearly four years, aiming to hedge against further price increases. Business confidence for the coming year improved to an eight‑month high, with firms citing strong demand linked to artificial intelligence, the launch of new products, and the acquisition of new clients as primary drivers of optimism.
