"There will also be regular collaboration between coaching and performance staff to share knowledge and expertise across both men's and women's football," Everton said in a statement.
Nagoya already had a similar partnership with Serie A side AS Roma, who are also owned by Everton's owners, the Friedkin Group.
Angus Kinnear, Everton’s Chief Executive Officer, said in the statement: “It is a true honour for Everton to be entering into a special partnership with Nagoya Grampus. This partnership reflects Everton’s ambition to build purposeful, rewarding and long-term relationships with organisations and clubs that share our values and vision.
"Nagoya Grampus is an organisation with a deep community focus and a clear commitment to development, and we’re excited about the opportunities this collaboration presents across football, commercial growth and social impact. We look forward to learning from each other and delivering meaningful benefits for both clubs – and our respective communities.”
Everton lost to Leeds United in their opening game of the new Premier League campaign on Monday. Nagoya are 16th in the J-League standings.
