First post and I know this one is a little niche but worth highlighting considering how expensive one way Y from Japan can be.
Singapore Airlines has cheap J flights from Japan, including HND/NRT, KIX and cough through Feb and March. Osaka has the best availability for me with a J ticket to Melbourne via Singapore costing just ¥157,670 (~$1600 aud). The booking UI doesn’t offer the free stopover but using multi city it was only ¥5000 ($50) more.
Note that only Tokyo airports have the long haul business class product while other airports use the regional config, all lie flat though
