Obituary For James Walton Kostenbader

James W. Kostenbader died suddenly July 15, 2026.

For his entire life, Jim was beloved by all who knew him. Jim was born in 1954, the eldest son of Marie and Walton Kostenbader of Hope, NJ. There he grew up on Kostenbader Road. During Kindergarten, he developed a friendship with Jean Vohl, also of Hope. After graduating from Belvidere High School (NJ), Jim and Jean married in 1974. That early friendship grew into a lifelong love for and devotion to each other that served as an inspiration for so many others. They would have celebrated their 52nd wedding anniversary in August.

Jim and Jean have lived in Rapid City since 1974. Jim founded JK Crane Service of Rapid City, where he served as owner and operator. Over the years, his business contributed to many construction projects within the Black Hills and its surrounding areas.

Jim’s joys during his lifetime included motorcycling, golfing, boating, oldies music and, most recently, watching reruns of vintage TV shows with his cat, Alfie. Helpful, patient, easy-going and kind, as well as a fine friend, Jim could be counted on to help with any problem and could fix just about anything. His quiet sense of humor endeared him to all.

Jim is survived by his cherished and loving wife, Jean, and his dear and loving son and daughter-in-law, Billy Kostenbader and Erika Toyoda, all of Rapid City, SD. He is also survived by his sister, Suzie Stocker and family of Yardley, PA, and by many, many friends and family members throughout the country.

Jim is preceded in death by his parents, and by his brother, Tom Kostenbader.

Funeral arrangements will be private.
