The mother of a Gloucestershire man serving a 14-year prison sentence in Japan for drug smuggling is to fly out to hear the result of his appeal.
Baker was also fined more than £25,000
Nick Baker, 34, from Stroud, says he was duped into carrying ecstasy tablets and cocaine which were found in his suitcase at Tokyo's Narita Airport.
He is due to find out on Tuesday if his appeal has been successful.
Iris Baker, who lives in Wiltshire, has previously raised fears about her son's mental and physical state.
Baker has always claimed the suitcase containing the drugs belonged to his travelling companion, James Prunier.
Mr Prunier, also from Stroud, was later detained and was awaiting trial in Belgium for similar offences when his body was found on a railway line in Gloucester last August.
A jury inquest into Mr Prunier' s death recorded a suicide verdict.
