Nippon Carbon has issued a final report on the fire that broke out at its Toyama Plant on August 29, 2025, where coke heated to around 3,000°C was violently ejected from a graphitization furnace used in artificial graphite electrode production. The blaze, which was fully extinguished by August 31, caused partial damage to a 10,907.45 m² building but resulted in no injuries and did not spread to nearby properties. Investigations by fire authorities and the company concluded that volatile components generated in the furnace triggered a small internal explosion, leading to coke ejection, melting of adjacent cooling water pipes, and a subsequent large-scale coke blast when water vaporized inside the furnace. Nippon Carbon found no evidence of equipment abnormalities or human error, and it plans to resume operations with changes to furnace loading methods, installation of coke-ejection covers, and redesign of water pipe specifications and layout to prevent recurrence. The company recorded ¥803 million in fire-related extraordinary losses in its consolidated results for the fiscal year ended December 31, 2025, mainly for restoration costs. However, it reported that the impact on its artificial graphite electrode supply chain has been extremely limited thanks to the use of other production facilities and related countermeasures, mitigating broader disruption for customers and stakeholders.
