TOKYO (Reuters) - A Vietnamese man held in a solitary cell at an immigration detention centre in Japan died on Saturday, raising fresh questions over the monitoring of individuals in the country's detention system.

The man died at the East Japan Immigration Center in Ibaraki prefecture, northeast of Tokyo, a spokesman for the centre said on Monday. Two men, one of whom was also held in a solitary cell, died at the same facility in 2014.
