Prime Minister Abe's speech in February 22, 2013 at the CSIS in word cloud - Japan More Japanese. Other than those words and a few others, the words are mostly of equal sizes. Probably an indication of flat, unfocused speech.
For comparison, Mr. Seiji Maehara's speech in September 12, 2012 for the Congressional Study Group on Japan of FMCin word cloud - Japan United States Alliance Important Security Cooperation
It almost makes me wish Maehara were the prime minister.
