> “On top of that, with inbound tourism and eating out resurging as we came out of the pandemic, demand increased,”

Why does eating out increase demand for rice, rather than just shifting the same volume of consumption from being through homes/grocery stores to restaurants? Do people eating out pick rice more than people cooking at home? If this was true, and if people aren't in general eating more ... then have prices for some other foods that are more popular for home meals commensurately decreased?

I don't know about Japan but in the states it is common for a restaurant to serve you a large portion, otherwise some patrons would claim they're not getting a good value. It's quite normal to not be able to finish it, and unless you ask for a to-go container, it'll go to waste.

There's a lot of possibilities, but one that springs to mind is that restaurants are quite wasteful compared to home cooks.

Well run restaurants waste as little food as possible, since that's all profit being thrown away.

Is this a theoretical restaurant or a real one? From what I understand real restaurants waste food by necessity because (for one example) mistakes are inevitable, customers are picky/mercurial, and any prepared dish that is deemed less than suitable for one customer for any reason can’t be sold to any customer.

Also equipment fails, vendors mess up, etc.

Having run a restaurant, this was not my experience.

If saving 10c costs time worth more than that then it's not worth it. Ends there, really.

A friend used to work at a known cupcake chain in London and she literally threw out 30+ cupcakes a day. Whenever I was around, I'd try to convince her not to throw them but giving the box to some homeless or random passerby. Although that wasn't a common event given the boss.

So no, many places are stupidly wasteful, sometimes because of silly legislation.

You'd need perfect forecasting to not waste food. Order exactly enough food, and serve each customer exactly what they'd eat.

It's not about forecasting, but about being able to give food away instead of dumping it because "lost profits" and idiotic lawsuits on free food.

You skipped over the other part of what I wrote. The uneaten food that people leave on their plates is often more significant.

Similarly, tourism should only account for an increase in demand of a few percent at most (?), seems like a lazy and potentially harmful attribution
