Japan coach John Kirwan's future is hanging in the balance with officials mulling whether to ditch him after their winless Rugby World Cup 2011 campaign.
National rugby chief Tatsuzo Yabe says nothing has been decided about Kirwan but he says Japan must rebuild with the clock ticking before it hosts the tournament in 2019.
Japan finished this tournament with a one draw, three loss record.
