A person familiar with the situation told The Associated Press that Carole Ghosn is not a suspect and will be questioned voluntarily with Ghosn's legal team present. The person spoke on condition of anonymity because of the sensitivity of the matter.
Carlos Ghosn was arrested in November and charged with falsifying financial documents and breach of trust while leading the Japanese automaker. The charges allege he under-reported his retirement income and had Nissan shoulder dubious payments and investment losses.
He says he is innocent. He was released on bail last month but rearrested last week.
Prosecutors say the allegations that were the basis of his recent arrest are distinct from the others, while giving not details. The detention was approved through Sunday but can be extended.
Earlier this year, Carole Ghosn wrote to Human Rights Watch, criticizing Japan's criminal justice system as unfair and harsh.
