The following is what I got from the Japan Today online news re: Nobu's decision not to compete @Japanese Nationals:
Oda to miss national championships

TOKYO — Figure skater Nobunari Oda, who was suspended for riding a motorcycle while drunk last summer, will sit out the upcoming national championships and delay his planned return to competition, the Japan Skating Federation said Monday.
Oda has opted to miss the championships beginning Wednesday in Osaka, citing mental stress as the main factor for his latest decision, which also dashes his hopes of skating in the world championships to be held in Sweden in March.
