Excitingly, I've been in touch with Yuki Tanaka, who is related to a teacher at Xavier College. Yuki is an activist at the Hiroshima Peace Institute and also works in Melbourne for some of the year. Here is a video of Yuki, speaking about some of the issues related to the history of the War. Also, this is a link to a book he has written.
Could you take a look at this website: Please read Takahashi-san's testimony - Yuki recommends that we meet Takahashi-san if possible - would you be interested in this opportunity?
