The Japan standard terminals are smaller diameter, shown on page 16.
BTW there is some really good information in the appendices about testing, maintenance, and everything you ever wanted to know about lead acid batteries ∿
In the US we have a different numbering, BCI (Battery Council International) Group Size 151R
