According to his papers, Sodimedjo, also known as Mbah Ghoto (grandpa Ghoto), was born in December 1870, the BBC reported.
But Indonesia only started recording births in 1900 — and there have been mistakes before.
Yet officials told the BBC on Monday that his papers were valid, based on documents he provided and interviews with him.
He was taken to hospital on April 12 because of deteriorating health. Six days later he insisted on checking out to return home.
“Since he came back from the hospital, he only ate spoonfuls of porridge and drank very little,” his grandson Suryanto told the BBC.
“It only lasted a couple of days. From that moment on to his death, he refused to eat and drink.”
When asked about the secret of his longevity, Mbah Ghoto told the BBC last year that patience was key and that he had “a long life because I have people that love me, looking after me”.
A heavy smoker until the end, he outlived four wives, 10 siblings and all his children.
Suryanto said his grandfather was laid to rest on Monday morning in a local cemetery plot he bought several years ago.
If independently verified, his age would make Grandpa Ghoto older than French centenarian Jeanne Calment, who was 122 when she died, and is considered the longest living human in recorded history.
