    What is Koshihikari rice?

    Koshihikari rice (コシヒカリ)

    Koshihikari rice is both a rice variety and a brand of rice harvested in Niigata prefecture, Japan. Except for Hokkaido and Okinawa, “Koshihikari” is cultivated throughout Japan. The sweetness and stickiness of Koshihikari are what make it so appealing. When cooked, it has a lovely shine and perfume, as well as a strong umami taste, so you may eat it as is. It goes well with light Japanese cuisine when it comes to cooking. Commonly used for making sushi, the texture of this type of rice is soft, as Koshihikari rice has a high amount of resistant starch meaning it’s broken down slowly in the body raising blood sugar levels slowly.

    Japanese locals use the character for koshi (越) to represent the old Koshi Province, which stretched from present-day Fukui to Yamagata. They translate the word “Koshihikari” as “the light of Koshi”.

    Koshihikari rice History

    Koshihikari rice (コシヒカリ)

    Koshihikari, a Japanese short-grain rice cultivar, was developed in 1956, more than 60 years ago. Despite its age, it has been the most widely grown cultivar in Japan for more than 35 years, making it the most important rice for the Japanese people. The history of “Koshihikari” begins in 1944 during the war. “Norin No. 22” and “Nourin No. 1” were crossbred in Niigata Prefecture. The goal was to develop a cultivar that combines the characteristics of “Norin No. 22”, which is resistant to disease, and “Norin No. 1,” which has a high yield and excellent taste.

    However, since the end of the post–World War II food shortage in the 1960s, Japanese preferences changed from high productivity to good eating quality. This triggered a wide expansion of Koshihikari cultivation due to the cultivar’s excellent taste and texture.  Meanwhile, in 1965, Niigata Prefecture adopted it as a recommended breed ahead of the rest of the country. Despite the need for high-yield rice, the first priority was to produce delicious rice that emphasized quality and taste.

    With the increasing cultivation of Koshihikari in Japan, several good agronomic characteristics beyond its high eating quality became apparent, such as its good adaptation to different environments, tolerance to pre-harvest sprouting, and cold tolerance during the booting stage.

    The developers crossed Koshihikari with a disease-resistant type to create a cultivar known as ‘Koshihikari BL’. Niigata Prefecture chose to implement “Koshihikari BL” throughout the prefecture because it requires fewer pesticides than normal Koshihikari. They also offer “Koshihikari BL” as “Koshihikari” because it has the same quality and flavor as traditional Koshihikari.

    How do the Japanese make Koshihikari rice in Japan?

    Weighing and washing rice accurately and quickly

    Measure the rice accurately before cooking. When measuring with a measuring cup, put in a leveled cup, and flatten the edge of the cup with chopsticks or the like. When washing rice, first lightly rinse to remove dirt, and change the water quickly before the rice absorbs water.

    Remove the bran on the surface with rice polishing

    In conventional rice polishing, they remove the bran attached to the surface by the friction between the rice grains, similar to sharpening a knife. However, the current rice milling machine has a high performance of removing bran. Lightly sharpening the rice 2-3 times is enough to prevent the rice from cracking.

    Let the rice absorb water by soaking

    After sharpening, soak the rice thoroughly so that the water soaks into the rice. Approximately 30 minutes in summer and 2 hours in winter. Even if the rice is soaked too much, it will not accept more than a certain amount of moisture, but to prevent the growth of bacteria, do not leave it soaked for a long time.

    Adjust the amount of water according to your taste for firmness

    Adjust the amount of water according to your preference for the hardness of the rice. New rice is said to use less water, but unlike the old days of sun-drying, machine drying is the mainstream today, so there is no need to drastically reduce the amount of water. The point is to stir the whole evenly as soon as the rice is finish.
