The group has taken two floors in the building spanning over 3,800 square meters, announced BNY Mellon's chairman and chief executive officer Robert P. Kelly at the ribbon cutting ceremony attended by the bank's employees. 

 "The opening of our new Japanese headquarters underscores our long-term investment in the Japanese market, and on a broader scale signifies BNY Mellon's continued growth in Asia-Pacific," said Kelly. 

"There are many areas where further collaboration between BNY Mellon and Japanese financial institutions can bring great mutual benefit. We will continue to add the best people, products and services and ensure we deliver the full breadth of our company's capabilities to support our clients in this competitive global marketplace."

The New York-listed firm has been servicing Japanese institutions for almost 100 years and last year celebrated its 40th anniversary in Japan. BNY Mellon has $26.3 trillion in assets under custody and administration and $1.3 trillion in assets under management.

Last month BNY Mellon announced it would move its Korea HQ to the International Finance Centre in Seoul. Slated to be completed in 2012, the new office will overlook the Han River.
