In this paper, I will specifically and objectively identify critical opinions on the mass media that have developed on the Internet about a report giving the real names of the Japanese victims of the hostage crisis of January 2013 in Algeria, and consider the structural factors of such criticism. The targets of this analysis are 1262 cases of opinions output from highly-ranked Web pages displayed on a search engine listing using fixed criteria. 7.1% of the opinions supported the news report, 68.5% of opinions did not support it, with other opinions accounting for 24.4%. The results of an analysis of opinions that did not support the report by using a text-mining approach did not necessarily indicate criticisms of the report that used the real names of the victims, but were an accumulation of various feelings of distrust against the mass media expressed on the Internet that were triggered by this news report. In addition, opinions that did not support the report were formed using language structures peculiar to the Internet; namely, a cyber-cascade that began at the point where people critical of the mass media became sympathetic and radicalized as unclear information spread on the Internet.
