Barack Obama's half brother, Barracuda Obama, is doing well in Japan and wishes the Illinois senator luck in his quest for the U.S. presidency, the Tokyo Shimbun reported Tuesday.

In its annual April Fools' Day hoax feature, the Tokyo-based newspaper published a story about a 39-year-old Asian-African businessman who recently learned he was a child born to Obama's Kenyan father and an Asian woman.

Barack Obama Sr. divorced the senator's mother, Ann Dunham, in the mid-1960s. The spoof says Barracuda was born as the first of four children after Obama Sr. remarried his second wife in Nairobi.
