It seems that NHK is going to broadcast a program on ABC conjecture, which has been rumored for some time. On the website of a TV program table magazine, a program on ABC conjecture is listed as a scheduled broadcast of “NHK Special”.

The name of the program is “Can Mathematicians Connect the Universe? A Strange Story about ABC Conjecture (working title)”.
The website says that it will be broadcast on March 6, but there is no data for this program in the electronic program table currently available. The official website of NHK Special also lists another program to be aired on March 6.
It may have been rescheduled in light of the situation in Ukraine.
