Japan's major steel producers will likely cut their crude steel output in the current fiscal year ending in March 2026, partly because the US' blanket 25pc tariff on automobile imports will curb domestic car productions.
The country's largest and second-largest steel mill by capacity Nippon Steel and JFE Steel estimates crude steel output at 33mn t and 21mn t respectively in April 2025-March 2026, both down on the year by around 1mn t.
This comes as the US' tariffs on automobile imports is likely to cap domestic car production, according to the firms.
The US levy could potentially reduce several hundred thousand tonnes of its steel products sales given that 20pc of the Japanese domestic car production is exported to the US, said JFE.
Nippon Steel also forecasts lower steel demand because of a possible fall in auto and machinery exports to the US, although it is difficult for the company to evaluate the quantitative impact on the wider supply chain. Nippon Steel estimates Japan's total car exports to the US, including delivery via Canada and Mexico, is currently around 2.8mn units/yr, all of which could be subject to the US tariffs.
Nippon Steel is cautious about providing its output projections given the unstable climate over the ongoing trade negotiations between Tokyo and Washington.
Forecasting crude steel output for the current fiscal year is difficult given uncertainty over the possible impact of US tariff measures, Nippon Steel told Argus. JFE also said "further risk analysis is necessary", suggesting a possible revision of its production outlook.
Meanwhile, Nippon Steel expects no significant impact from the US tariffs on its direct steel products delivered to the country for the time being. The impact of the tariffs will be limited given the firm's value-added products such as high-alloy seamless pipe are exported in small volumes and difficult to replace with other products, the company said. Some of its US clients designate Nippon Steel as the supplier of these products because US local manufactures are unable to produce them, the company added. Nippon Steel did not provide their export volumes.
Domestic steel demand
Domestic steel demand is also unlikely to recover in the short term regardless of the US tariff.
The country's domestic crude steel output has been consistently falling over the past several years, but the recent downtrend appears to be especially worrying for the Japanese steel producers.
The current slump in domestic steel demand is more severe than expected, Nippon Steel said, forecasting the continuous downtrend in steel demand for most of the steel consuming sectors including auto, construction and manufacturing industries.
Sluggish demand has even led JFE to decide to completely close one of its steel production facilities.
JFE announced on 8 May that it will shut down its No. 4 basic oxygen furnace (BOF) steel plant in western Japan's Fukuyama sometime in April 2027-March 2028, as part of the mid-term strategy. This will reduce the company's domestic steel production capacity to 21mn t/yr, down by 500t from the 2024-25 level, the company added.
JFE decided to close the BOF plant because domestic steel demand is likely to continue falling on the back of shrinking populations and labour shortages, according to the firm. These are causing delays in construction projects and therefore weighing on steel demand, the firm added.
