Koshihikari for sure. Rinse until it’s clear. Could be 2-5 times.
Cal rose is a blend
Koshihikari is proper Japanese rice
Grown in California is good
But. Buying from japan is better.
I’m convinced they don’t export any of the good stuff.
Buy it there it’s always better. Has a sweetness and a “mochi mochi” texture that is hard to explain
Here we usually buy
Shirakiku Koshihikari
Or
The one in the green bag
Tamanishki is a hybrid and good too
