Prince Tomohito of Mikasa, a cousin of Emperor Akihito, was released from Keio University Hospital in Tokyo on Saturday after he was admitted for not feeling well.
Officials of the Imperial Household Agency said the 60-year-old prince had no particular medical symptoms but was hospitalized Wednesday as a precaution.
He was discharged from the same hospital Aug. 27 after experiencing symptoms of a minor heart attack.
In February, the prince underwent his seventh cancer operation and has been reducing his official duties to recuperate, they said.
