What is Your Main Concern?

Question: If you can know one thing out of the hikikomori research, what would you want to know about? Or put it this way, what is your main concern about hikikomorii? I'll try to accommodate these question into my research. Contribution of ideas are welcome, and if you would like to get involve in a certain degree, please drop me a line. Thank you!
