TOKYO, April 2 (Reuters) - Carlos Ghosn's lawyer on Tuesday said he did not rule out the possibility of additional charges in Japan against the ousted Nissan Motor Co boss.

Junichiro Hironaka also told a news briefing that he would not accept anything less than exoneration for Ghosn. Earlier on Tuesday Ghosn's legal team asked a Tokyo court that the executive stand trial for alleged financial wrongdoings separately from Nissan because the company was helping prosecutors.
