Statistical Error in Hikikimori Presentation

In the presentation, I mistakenly said that 10% of the Japanese population were hikikimori. I had gotten this statistic from a Japanese video, but I read it mistakenly. The actual number are thus:

According to psychologist Tamaki Saitō, who first coined the phrase, there may be one million hikikomori in Japan, representing 20% of all male adolescents in Japan, or 1% of the total Japanese population.

From: Saitō, Tamaki. 1998. Shakaiteki Hikikomori (Social Withdrawal). Tokyo: PHP kenkyuujyo.

Sorry for the confusion. It's still a big number, though.
