Usually, JSF tries to get their most popular/dominant skaters to compete at NHK Trophy - which means in recent times, Mao for the women and Daisuke for the men. The other federations who have a home GP try to do the same (Davis/White and Virtue/Moir with Skate America and Skate Canada, etc.).
As we know, Yuzuru and Daisuke that season were not supposed to meet each other during the GP series, as they were both in the top seeded group (1-2-3 at Worlds the previous year). Daisuke would have surely been the top choice between the two, based on results and popularity, but NHK that year was in Sendai, with Yuzuru being a symbol for the earthquake victims and home hero after winning bronze the previous season in Nice. So, JSF reached an agreement with the French fed, who was in their same situation, with a home GP (TEB) and two seeded skaters (Joubert and Amodio, both in the 4-5-6 seed group): in the end, Yuzuru and Daisuke skated at NHK, and Joubert and Amodio at TEB.
