I’m happy to be wrong, but this was the basis for saying that. I do agree that business class awards show up on Qantas.com.
As far as I understand, domestically in Japan or JL there is: First Class, Class J and economy.
On my OWA, even where the consultants could see the domestic JL availability, they couldn’t see business even where it showed up as such on Qantas.com.
JAL’s website also says:
“Class J cannot be used for Japan domestic sectors included in International award tickets.”

British Airways and American Airlines don’t show up business class options for domestic Japan, even for flights where there is business showing on Qantas.com.
I would be genuinely happy to hear that it is possible though - have you checked your seat allocation for the JL flights to make sure that it’s offering up Class J or First class seats? Is this for a domestic-only ticket? Cheers
