Foreign journalists charged with covering Japan's devastating March 2011 disasters faced an enormous challenge: sensitively expressing the human tragedy while accurately assessing the vast amount of real-time data on the crisis.

Some failed, as seen by the wildly inaccurate reports broadcast in certain overseas media, including a supposed nuclear reactor in the heart of Tokyo and a "mass exodus" from the capital. But many succeeded where the local media hesitated, particularly those journalists objective enough to draw criticism from both sides of the nuclear debate.

One such journalist was Tokyo-based Australian Mark Willacy, who was in the right place at the right time for a newsman when the disaster struck. However, in an interview to discuss his new book on the crisis, "Fukushima," the experienced correspondent for Australia's ABC said it was not always easy keeping emotions in check.
