Former Nissan chief Carlos Ghosn, who was awaiting trial in Japan on financial misconduct charges, has flown to Lebanon.
In a statement, the 65-year-old said he would "no longer be held hostage by a rigged Japanese justice system, where guilt is presumed, discrimination is rampant, and basic human rights are denied".
"I have not fled justice - I have escaped injustice and political persecution," said Mr Ghosn, who vowed to communicate "freely" with the media "starting next week".
It is not clear how he managed to leave Japan, as his bail conditions prevent him from exiting the country he had been held in since his sudden arrest in November 2018 sent shockwaves through the business world.
Mr Ghosn and his lawyers have repeatedly voiced fears over the impossibility of a fair trial in Japan and have called for the case to be thrown out, citing missteps by the prosecutors' office.
Lebanon said Mr Ghosn - who holds Lebanese, French and Brazilian nationalities - had entered the country "legally".
"There are no measures that warrant taking steps against him or prosecuting him," the country's General Security apparatus said.
Lebanon's foreign ministry said there was no accord for extradition or judicial cooperation between Beirut and Tokyo.
Lebanese media reported Mr Ghosn had flown by private plane from Turkey to Lebanon, where his parents were born and where he spent most of his childhood, after arriving there as a toddler.
Many Lebanese view Mr Ghosn as a symbol of their country's large diaspora, and a prime example of Lebanese entrepreneurial genius and have been shocked by his arrest.
But in Tokyo, the unexpected turn of events will spark questions about how he could apparently have given authorities the slip.
His Japanese lawyers were seemingly caught unawares by his travel plans and declined to comment to reporters.
Public broadcaster NHK cited a foreign ministry official as saying: "He was not supposed to leave the country. Had we known about it beforehand, we would have reported that to proper law enforcement authorities."
Government officials could not be reached immediately on a public holiday.
His sudden departure from Japan is nearly as dramatic as his arrest out of the blue at a Tokyo airport.
Prosecutors stormed his private jet in scenes captured by a local paper, and whisked him off to a Tokyo detention centre where he spent more than 100 days in spartan conditions far removed from his sometimes extravagant lifestyle.
He eventually won bail, striding out of the detention centre disguised in a workman's uniform complete with mask and cap in an apparent bid to fool the world's media camped outside.
Then one morning in April, he was re-arrested on another set of charges just days before he was due to give an anticipated news conference.
He released a video apparently pre-recorded in which he accused "backstabbing" Nissan executives of a "conspiracy".
Later that month, he was released again on bail - this time leaving in a business suit - and he had been in Tokyo ever since preparing for his trial in "combative" mood, according to his lawyers.
He stands accused of two counts of under-reporting his salary to the tune of 9.23 billion yen ($85 million) from 2010 to 2018, deferring some of his pay and failing to declare this to shareholders.
Prosecutors also allege he attempted to get Nissan to cover around 1.85 billion yen in personal foreign exchange losses during the 2008 financial crisis.
The fourth charge against him is that he allegedly transferred millions from Nissan funds to a dealership in Oman, from which the executive supposedly skimmed off $5 million for his personal use.
He has consistently denied all charges against him, saying they are a "plot" by Nissan executives to get rid of him because they feared he was moving the Japanese firm to a closer tie-up with Renault.
