In Inoue and Sato, 2023, a new mutation CTS7645 was reported for one of yDNA O1b2-47z>…>CTS713 branches, which is absent on the yFULL site or on the ISOGG site:

O1b2a1a1 CTS713, CTS7776, CTS8032, CTS10145, CTS10341, CTS10674, CTS11723, CTS11986, K7
O1b2a1a1a CTS1875, CTS7465, CTS8777
O1b2a1a1a1 CTS10682, CTS1966,CTS3764.2, CTS3926, CTS6725, CTS7366, CTS8034, Z24596
O1b2a1a1b Z24598, Z24599
O1b2a1a1c CTS203, CTS6622, CTS9892
Nonetheless, the mutation CTS7645 is present in one of the branches of yDNA O-M122>…>L465>CTS727, akin to Han Chinese.
In 2021, in "Human population history at the crossroads of East and Southeast Asia since 11,000 years ago", the connection formed between the Japanese yDNA O1b2-47z>…>CTS713* sample and the Late Neolithic Yellow River Haojiatai HJTM109 yDNA O-M122>…>L465>CTS727 sample, which is mediated by the Lower Xiajiadian culture’s yDNA O-M122>…>L465>IMS-JST002611 sample. Since both main branches of yDNA O-M122>…>L465 are simultaneously involved (CTS727 and IMS-JST002611), it should cover a CTS7645-affiliated population as well, thus, populations of millet farming cultures, the closest one being the Lower Xiajiadian culture, mediated the appearance of the yDNA O-M122>…>L465-related population’s component in the Japanese yDNA O1b2-47z>…>CTS713* sample in "Human population history at the crossroads of East and Southeast Asia since 11,000 years ago".
