In the manga, he was a politician for the Democratic Liberal Party (there is a real political party in Japan called the "Liberal Democratic Party," the current ruling party at the time of the series). Rei hated him and went to live with her grandfather instead because he never came to see his wife in the hospital when she was dying. Rei would meet with him every year on her birthday in a restaurant, and he would always give her a white dress and a bouquet of casablanca lilies, which in actuality had been picked out by his secretary Kaidou.
Pretty Guardian Sailor Moon
In the live-action series, he was once again a busy politician who never came to visit his wife (here given the name Risa) in hospital when she was dying. He hated his daughter's special powers, and because of this he left her at the Hikawa Shrine, only meeting her once a month in order to look good for the media. His secretary in this version was called Nishizaki, who did not have a relationship with Rei.
- His given name can also be read as "Takashi," an alternative pronunciation of the kanji characters in his name, which has led to confusion in fandom. However, the furigana accompanying his name in the Pretty Guardian Sailor Moon Memorial Book indicated that it should be read as "Ryuuji."
