> I pay somewhere around AUD$14/kg for Japanese rice in Australia

a 10kg bag of (AU-grown) koshihikari at Hanaromart (some Asian supermarket) is around 43 AUD right now IIRC. Could I tell the difference in blind tasting between it and just "normal" koshihikari off the shelf off a Japanese supermarket? Maybe, but maybe not. Not an argument for removing trade barriers, but the gap right now seems pretty stark.

I do feel like it's worth thinking about how you're saying 800 yen, but that might be per person. So for a 3-person family that's almost ~120k JPY per year. If you could cut that down to 90k JPY per year thats an extra 2500 JPY per month you can spend on food.

If you're the kind of person who only goes to the discount shops, an extra 2500 JPY per month can go a decent way on food. If you are on a pretty strict/limited food budget that 2500 JPY could go a long way.

Though of course like with eggs, etc, all food prices are just more obvious as well. And Japan has had really nasty inflation with energy + the weakening yen as well, so this is yet another thing that saps away at a budget where you're probably not saving that much to begin with.
