A 27-year-old Japanese visitor died Tuesday after he became unresponsive while scuba diving off south Oahu.

The Honolulu medical examiner’s office identified the man as Tatsumi Umemura of Nagoya, Japan.

The cause of death is pending the results of an autopsy.

Paramedics took Umemura to a hospital in critical condition and he later died.
