I can buy rice at Costco in the US for $25 for 50lbs, which is equivalent to 854 yen for 5KG. A bit less than 1/4 the cost of Japanese grown rice.

They have a completely different consistency when cooked and are used for different things.
it's has a similar stickiness, the taste is a bit different, but better imo.
it pairs well with asian dishes as opposed to american rices and can be used for sushi.
it's not 1:1, but it's certainly a good substitute when you can find japanese rice.
