Overview of Japan’s Powder Metallurgy Product Output in 2025
According to statistics from the Japan Powder Metallurgy Association, in 2025, the production of powder‑metallurgy mechanical parts totaled 59,275 tonnes, down 1.2% year on year, while oil‑impregnated bearing production reached 3,963 tonnes, a decrease of 0.4% compared with the previous year.
Production volumes for other product categories were as follows: friction materials, 689 tonnes, down 8.3% year on year; electrical contacts, 62 tonnes, up 19.2% year on year.

In 2025, the output of powder metallurgy mechanical parts for automobiles is projected at 55,774 tonnes, down 1.3% year on year. Overall production remained broadly stable, but the demand structure—covering downstream end-use sectors—has undergone significant shifts: the output of components for internal‑combustion engines continues to decline, while the production of hybrid‑vehicle‑related parts, electric‑assist components, and magnetic‑material parts has been steadily increasing.
Looking ahead, given the deceleration in the pace of electric vehicle adoption, overall production capacity is expected to remain broadly stable compared with 2025. However, amid multiple factors—including shifts in demand structure, tariff policies, and geopolitical dynamics—the industry’s medium-term outlook remains subject to significant uncertainty.
In the industrial machinery sector, output has exhibited divergent and volatile trends across downstream application segments; however, overall output value has bottomed out and is now experiencing a modest rebound.
The motor and electrical equipment industry has experienced volatile output due to inventory destocking. Although certain sub‑segments may see room for demand growth going forward, the sector’s long-term downward trend is unlikely to reverse.
Production of oil‑impregnated bearings for automotive applications totaled 2,862 tonnes, up slightly by 0.1% year over year, with overall output remaining broadly stable. Although demand for electric‑vehicle components increased, this gain was offset by a decline in demand resulting from customers’ inventory adjustments.
In the first half of the year, orders in the industrial machinery segment weakened due to tariff-related headwinds; in the second half, demand for construction machinery rebounded, resulting in overall production remaining flat for the full year.
In the electrical machinery sector, production of bearings for fan motors has increased. However, with the exception of high‑function and high‑performance products, capacity in other product categories continues to shift overseas.

In 2024, the per-vehicle usage of powder metallurgy sintered components is: 7.1 kg in the Japanese market, 14.8 kg in the U.S. market, and 8.4 kg in the European market.
