Are there any members of Sadako Sasaki's family members still Alive?

Yes, I believe her brothers and sister are still alive. Their names are Masahiro, Eiji and Mitsue. Her father Shigeo died in 2003. Her mother Fujiko, I think passed away, but I'm not sure. I met Sadako's father in 1993. My friends father was his uncle. He was a very nice man. He took me to Sadakos gravesight in Fukuoka.
