Shipmanager Wallem has its first Japanese-flagged ship under control.
NYK's 6,333-ceu Aphrodite Leader (built 2007) switched registers from Panama following various inspections, audits and surveys, it said.
"This marks a positive milestone as Wallem is now one of just a few international ship managers capable of managing Japanese flag vessels," the company said.
"It is a clear testament to our strong safety culture, commitment to quality and efficient operations."
