British Swimming has announced that Chris Spice, a former performance director for the RFU, Great Britain and England Hockey and British Basketball, has been named new national performance director and Bill Furniss, the coach of Rebecca Adlington, as new head coach.
Both will begin their roles in April and will continue for another three years through to the Rio de Janeiro Olympics.
Kosuke Kitajima, Japan's best male swimmer, has shelved plans to retire from the sport, saying he wants to continue through to the 2013 World Championships.
Kitajima, 30, is confident he can return to form, after he didn't win any individual medal at the London Olympics, and be competitive for the 2013 World Championships.
He is entering 50 and 100 metres breaststroke at Japan Nationals on April.
