This was an interesting documentary by NHK World that looked at the children of Japanese soldiers and their Vietnamese wives. A friend sent me the link when I mentioned to him about attending a Japanese party here in Saigon there roughly 14 of the children were all half Japanese and half Vietnamese. This topic has always been an interest of mine since I have always wondered if there were mix Japanese/Vietnamese children of war in Vietnam.
It is a great documentary. You can watch the video at this link -> https://www3.nhk.or.jp/nhkworld/en/vod/worldprime/3016011/
