NO. My name is Toshihiro Kayama, and I don't have a middle-name.
The name YUZO causes on my family-name. Family-name "Kayama" is a little rare but famous in Japan, because of actor names YUZO KAYAMA. Although his and mine are different in Chinese Characters, I have been called "Yuzo" and given my handle as "Yuzo" sometimes (especially on the air).
I found a webpage about YUZO KAYAMA written in English and Japanese.
This is official page about YUZO KAYAMA, but written in Japanese.
