Oda was proclaimed the winner of the Japan Championships ahead of Takahashi, until a glitch in the computer software was discovered and he fell to second place; he had done too many combinations. The Japanese federation decided to split the international assignments between Oda and declared-winner Daisuke Takahashi, sending Oda to the 2006 World Championships, and Takahashi to the Olympics, in as much as Japan had only one spot for each competition after the withdrawal of Takeshi Honda from the 2005 World Championships and Takahashi's 15th-place finish at that competition. Oda placed fourth at his first World Championships, earning Japan two spots to the 2007 Worlds.
