His recovery was further complicated by fluid on his lung, which was removed last Wednesday.
Until the end of March, Naruhito, 44, will stand in for his highly-respected father who has been ordered rest in the Imperial Palace.
But his appearance at the anniversary service was a boost for people still trying to rebuild their lives.
He said: "It is my hope that our hearts will always be with the afflicted people and the afflicted regions, and that everyone will continue to work towards improving the conditions of those areas.
“It is important for us to never forget this disaster and hand down the lessons to future generations."
