Fujifilm is investigating a potential ransomware attack that resulted in the company closing down part of its network.
The company is investigating "possible unauthorized access" to its server, it said in a statement.
The company first noticed the "possibility" of a ransomware attack on June 1 and took swift action to discontinue all compromised systems.
"We are currently working to determine the extent and the scale of the issue," it said on its website, and that it "apologises to its customers and business partners for the inconvenience this has caused.
"For some entities, this affects all forms of communications, including emails and incoming calls, which come through the company's network systems," said the company.
In an earlier statement, Fujifilm confirmed that the cyber-attack is preventing the company from accepting and processing orders.
Japanese organizations have experienced other notable breaches in recent months. In March, Yamabiko, a Tokyo-headquartered manufacturer of power tools and agricultural and industrial machinery, was apparently added to the data leak site used by the Babuk group.
In May, a subsidiary of Japanese tech giant Toshiba admitted to suffering a cybersecurity breach, reportedly caused by the DarkSide ransomware gang.
Ransomware hackers have gone after larger targets in 2021. This month saw a ransomware attack on the world’s largest meat processing company and May saw a sophisticated ransomware attack on Bose, which resulted in the unauthorized access of personal information on current and former employees.
