Jones, who has recruited a high-profile backroom coaching staff including former South Africa second row Victor Matfield and ex-All Black Owen Franks, has said he believes he can take Japan to a first World Cup semi-final at Australia 2027.
Jones has impressive pedigree at the tournament, having taken his native Australia to the final in 2003 and been a coaching advisor for the victorious South Africa team of 2007.
During his first stint with Japan, he oversaw an upset victory over South Africa in 2015, before he led England to the final in 2019.
However, his record was blemished at France 2023 where he was in charge of an Australia team that suffered the nation's first-ever pool stage exit.
