-- NPR-Riken (TYO:6209) said it will terminate domestic production of certain casting components, excluding camshafts, by September 2027 as part of a business portfolio review, according to a Monday filing on the Tokyo Stock Exchange.
The move comes amid declining demand for cast iron automotive parts in Japan, driven by lower domestic vehicle production and a shift toward aluminum components and overseas sourcing.
The affected business reported net sales of about 5.1 billion yen and an operating loss of 725 million yen for the fiscal year ended March 2025, accounting for roughly 3% of the company's consolidated revenue.
