Japan Junior Figure Skating Championships
The 2005–06 Japan Junior Figure Skating Championships were held between December 10 and 11, 2005 at the Big Hat in Nagano.

The following skaters placed high enough at Novice Nationals to be invited to compete here: Satoshi Nakamura (1st in novice A boys, 20th in junior), Ayane Nakamura (1st in novice A girls, 9th in junior), Yuki Nishino (2nd in novice A girls, 16th in junior), and Miruku Matsushita (3rd in novice A girls, 14th in junior).

Winter Olympics
The picking of the Olympic Ladies team used a complicated formula that took into consideration the season as a whole along with other previous competitions, not just the results of the National Championships. Therefore, sixth-place finisher Miki Ando was chosen ahead of fourth-place finisher Yoshie Onda and fifth-place finisher Yukari Nakano. However, Nakano was picked ahead of Ando for the World team.
