I'm not sure tarrifs have a huge impact; Japan is Australia's largest buyer of rice, importing $63.8MUSD worth in 2023 per the OEC: https://oec.world/en/profile/bilateral-product/rice/reporter.... That's a lot of rice to buy, if it's more expensive and less desirable then domestic rice.
> The government imports 770,000 tons of rice tariff-free annually under its minimum access quota, and places up to 100,000 tons of that up for auction. Private-sector imports, which are separate from that framework, are subject to a tariff of 341 yen ($2.35) per kilogram, a measure intended to protect domestic producers. [1]
Since 1995 Japan has been forced by the WTO to import a certain amount of rice tariff-free every year. Much of it doesn't even go to Japanese consumers, but rather to animal feed and strategic reserves. Prior to 2024, virtually all imported rice in Japan was imported to satisfy this requirement. Presumably that also includes the $63M of rice imported from Australia in 2023.
The tariffs do indeed have a massive impact, and until recently it was very difficult for consumers to even find imported rice in supermarkets.
I see cal-rose for shy above 3000 yen. While I didn't grasp the details, I saw a news report which made it seems they've set up a quota (xx tons or something) of rice to be imported with almost no tariffs.
That sounds possible, I can get premium calrose at 4.5kg for 20$, which adjusted to be 5kg is like 3200 yen or it could be regular quality calrose marked up, I can get that for half the premium price so equivalent of 1600 yen.
