Roy was born on July 14, 1937, in Rock Springs, Wyoming, to Wataru and Fumie Kamigaki. He was the eldest of four children, growing up alongside his brother, Kenneth, and sisters, Jeannie and Bonnie. Roy was raised in Syracuse, Utah, where he helped on the family farm and developed a strong work ethic that would guide him throughout his life.
During his high school years, Roy met his first wife, Ada Carrol Watts. After graduating, they married, and Roy enlisted in the United States Air Force, serving in Korea. He trained as an air traffic controller and was then stationed in Dover-Foxcroft, Maine, where he and Carrol welcomed two children, Martin Thomas and BJ.
Following his service, Roy began a long and successful career with the Federal Aviation Administration (FAA), which spanned more than 30 years. Shortly after returning to Ogden, Utah, Carrol passed away unexpectedly, leaving Roy to raise his young children with the loving support of his family.
In time, Roy met Margaret K. Swainston, who would become his beloved wife and lifelong partner. They were married on April 3, 1961, and together built a family filled with love and laughter. Two more sons, Roy David and Michael Kelly, completed their family while they lived in Salt Lake City.
In 1976, Roy accepted a transfer to the FAA facility in Longmont, Colorado, where he and Margaret made their home for the remainder of his career and life.
Roy’s faith was a guiding force. A lifelong member of The Church of Jesus Christ of Latter-day Saints, he served in many leadership positions over the years, including as Stake President from 1999 to 2009. In that role, he provided spiritual guidance, comfort, and service to countless individuals and families—a reflection of his deep compassion and commitment to others.
Roy was a proud graduate of Davis High School in Kaysville, where he excelled in baseball and wrestling. His love for sports and the outdoors continued throughout his life. Whether he was golfing, fishing, camping, bird hunting, watching the Broncos, or riding his recumbent bike with his loyal companion, Lucky, his Jack Russell Terrier, Roy found joy in every moment.
Roy and Margaret also shared a love of travel, often visiting South Dakota, Hawaii, and Utah to see family. One of the highlights of their adventures was a trip to Japan, where Roy had the opportunity to connect with relatives and learn more about his family heritage—an experience that touched him deeply.
Roy is survived by his devoted wife Margaret Kamigaki; his children Martin (Cindy) Kamigaki of Longmont and Mike (Stacy) Kamigaki of Mead; grandchildren Jennifer Kamigaki, Charissa (Ted) Kamigaki, Jason (Ashley) Kamigaki, Cameron (Edgar) Kamigaki, and Taylor (Baylie) Kamigaki; nine great-grandchildren; one great-great-grandchild; and eight nieces and nephews. He is also survived by his siblings Jean Sumida, Kenneth (LouAnn) Kamigaki, and Bonnie (Richard) Hamp.
He was preceded in death by his parents, Wataru and Fumie Kamigaki, and his children BJ Kamigaki and Roy David Kamigaki.
Roy will be remembered for his integrity, strength of character, humor, and steadfast love for his family. His legacy lives on in the generations who follow and in the countless lives he touched through his faith, friendship, and example.
