I have a question about the wrestler Kintaro Kanemura... more presicely, about his name. I know that earlier in his career he wrestled as Yukihiro Kanemura. Why did he change his name? Does either name (Yukihiro or Kintaro) have another meaning in Japan? Is it a situation where one name is a more masculine name (i.e. "Chuck" vs. "Corky")?

I was also wondering the same thing about the wrestler Ryuji Yamakawa... didn't he wrestler as Seiji Yamakawa earlier?
