Katagami was re-elected as an executive director in June 2023.[9]
In February 2006, the JSA announced on its official website the engagement of Katagami to women's professional Madoka Kitao.[10][11]
On June 12, 2016, Katagami posted on his personal blog that he had gotten divorced some time ago, and that he had gotten married again to someone else about two months earlier.[12] The following day, Kitao tweeted that she and Katagami had gotten divorced about two years earlier in response; her tweet included a link to Katagami's blog post.[13]
