Kikuchi’s wife, freelance reporter Rumi Fukatsu, is a newscaster on NHK BS1’s World Sports MLB. For Kikuchi, it was love at first sight when he saw her in the fall of 2013. He tried to set up a meeting through a mutual acquaintance, but was continually turned down for two years because she wanted to maintain a professional relationship with athletes. He finally managed to organize a casual dinner get-together that included a mutual friend in November 2015. They started dating in December and he ended up proposing just before the start of the season in March 2016. They filed marriage papers on her birthday, June 24.
