In 1972, World Environment Day was established by the United Nations General Assembly to raise global awareness concerning protecting nature and the planet Earth. Every year on June 5th, YKK Group offices around the world plant trees to recognize this special day.

To commemorate World Environment Day, the Anaheim, California YKK (U.S.A.) Inc. office planted a native Majestic Beauty Indian Hawthorne tree on June 5, 2017.

On June 5, 2017, Tape Craft Corporation, a subsidiary of YKK Corporation of America, planted Leyland Cypress trees in celebration of World Environment Day.
