I know someone posted these recently, but those were for August dates - these are for November 2023 and then late January to May 2024.
These include 2 x 23kg checked bags, food etc; and they fly into Haneda. Possible to make these work during ski season!
The sub -$1k price I have listed is through an OTA (Online Travel Agent), add $60 if you want to book direct through the airline. Use Google Flights to find dates using their calendar feature.
Sydney to Tokyo $999

PSA spend the extra $60 and book directly with JAL.
There have been too many cases recently with travel agencies screwing over customers when it comes to refunds/changes.
JAL support is very good and you should have your issue resolved in under 15 minutes for 99% of enquires.
