Well, since this is back in, I guess I should chime in.
It’s not true
A few years ago, when the story was making the rounds, I did some private research. I spoke with some Koreans who live in Korea and one Chabadsker living in Japan, I searched on Naver (Korean equivalent of Google) for words I got translated from Google Translate (words like “Talmud”, “Jewish”, and “Torah”). The result? Several decades ago, a Rov in Japan published a series of Mashals and other stories from Bavli in Japanese. More recently, a Korean Christian publisher had the book partially translated to Korean and published as an illustrated children’s book simply called “The Talmud”.
