Joichiro Yukihira is the widowed father of Soma Yukihira. Like his son, Joichiro is laid back but professional and has a serious side that emerges whenever he is cooking. His skills in cooking are world-famous. He is noted to have a manly aura. As the sole parental figure in Soma's life, he is a mentor, teacher, and rival to his son, though he never pushed Sōma to become a chef, allowing Soma to develop that interest on his own. Joichiro is, if anything, very supportive of his son and the two share many similarities such as the shared habit of creating horrible dishes and feeding them to unsuspecting people which proves their connection. Despite this, Joichiro does occasionally like to see Soma stressed and frustrated by challenging him to many cook-offs which have always ended in Joichiro's victory. Again though, this is to show Soma how much more he has to grow.
