Utako Nagamitsu's relationship with Daisuke somehow reminds me of Machiko Yamada's (another important figure skating coach from Japan!) relationship with Midori Ito.
Both Dai and Midori are from families of rather modest means, and they would not have been able to continue skating without financial support from those who were impressed by their unique talent. Midori was sponsored by Yoshiaki Tsutsumi, a former owner of Seibu Railway Group and a die-hard figure skating fan, since she was a junior high school student. Officials of Okayama Skating Federation used to collect donations amongst themselves to send Dai to competitions abroad.
Midori lived with Machiko since she was 14, so that she could concentrate on skating. Utako invited Daisuke to live with her when he moved to Osaka to start university, in order to save on daily expenses, and he stayed there until 2009.
It's amazing to think until he moved to Osaka, Dai was practising at his home rink in Okayama, where no professional coach was available, during the week, and went to Osaka to be coached by Utako at weekends. He still managed to win the World Junior Title though.
