Ms. Mori continued the defense on Monday.
“We acknowledge that there are various criticisms of Japan’s criminal justice procedures, but every country has a different criminal justice system,” she said, adding, “It isn’t appropriate to simply focus on one part of the system when comparing it to other countries.”
The details of Mr. Ghosn’s escape are still emerging.
In Japan, local media outlets have reported that surveillance cameras showed him leaving his Tokyo rental home by himself on Dec. 29. According to media reports in Turkey, he boarded a private jet in the Japanese city of Osaka and flew to Istanbul, then took a second plane to Beirut.
The Wall Street Journal reported on Sunday, citing an anonymous source, that Mr. Ghosn was smuggled through Kansai International Airport in a type of box often used for concert equipment. It said the terminal for private jets at that airport was essentially empty, and that oversize luggage could not fit in the airport’s scanners.
A customs official at the airport, Akira Taniguchi, said that screening of luggage was done in two stages. In the first, a private security company using X-ray and other equipment checks whether there are items that are not allowed on board, likes guns or knives.
In the second stage, customs officials check whether the bags contain items that are not permitted to be brought in or taken out of Japan, like drugs and some foods. They use X-ray machines, metal detectors, drug detectors and dogs for that step.
Asked if Mr. Ghosn had managed to elude these measures, Mr. Taniguchi said, “We cannot comment on this.”
