Jeff T. Nakamura was a senior member of the Responders in Flatwoods before 2102. He was their quartermaster and was also assigned to reconnaissance and foraging in Morgantown near their headquarters. Maria Chavez wrote to him with the idea of sending a team to scavenge Gauley Mine.
Sometime after the Great Flood incident of Charleston, Jeff proposed to a Vault-Tec University graduate, Amy Kerry, near Summersville. However, rather than accepting, Kerry insisted that they both focus on rebuilding Appalachia.
Jeff Nakamura is mentioned only in Fallout 76.
