- A new brand Hokkaido rice debuted in 2020. "SANSANMARU" is the first Japanese rice cultivated by direct seeding with low amylose content, saving time in the rice growing process. Since this new rice is formed by the same gene of YUMEPIRIKA, which is the most expensive and popular rice in Hokkaido, it is of a stickier and soft texture and has good sweetness. Oxygen absorber packets help to preserve freshness of rice and prevent growth of pests, with no side effects.
