Kevin McGeever was brought before Strokestown District Court, Co Roscommon, in the west of Ireland after he was arrested in Dublin on Tuesday.
The 68-year-old, whose address was given as Nirvana, Co Galway, will appear before Harristown Court in Castlerea, Co Roscommon, on Friday.
He has been remanded in custody after being charged with wasting police time.
McGeever, orginally from Swinford in Co Mayo, disappeared last May.
He was found wandering barefoot on a road in Ballinamore, Co Leitrim in the west of Ireland in January.
The developer, who had lived in a mansion in Co Galway before he disappeared, was described as dishevelled, with a long beard, hair and fingernails.
Passersby found him malnourished, dehydrated and several stone lighter with the letters "tief" scrawled into his forehead. They took him to a local Garda station.
The defendant's brother Brendan described his sibling as looking like "a weather beaten 90-year-old man who was just released from a concentration camp".
McGeever is charged under Section 12 of the 1976 Criminal Law Act, relating to knowingly giving false information that an offence had been committed and wasting Garda time.
The charges allege McGeever made false reports and statements to Gardaí, between 29 January and 28 February this year, that false imprisonment, assault, and threats to harm had occurred.
McGeever sat in a packed courtroom surrounded by dozens of other defendants on minor charges before his case was called.
Dressed in a black leather jacket and blue and white striped shirt, the property developer did not speak during the brief hearing.
Solicitor Joan Devine, acting on behalf of McGeever's Dublin-based solicitor Tom Brabazon, requested a lower bail amount of €8,000 euro be set - after the judge set bail at €10,000.
"He is not in a position to come up with that kind of money," Ms Devine said.
Judge Geoffrey Browne rejected the application and remanded McGeever in custody with consent to bail.
