Japonica is often a medium-grained rice with relatively rounded grains, which makes it noticeably distinct within the skinnier, extensive-grained rice that we're used to in the West, which is recognized as indica rice. Japonica rice is starchy, with increased levels of a starch referred to as amylopectin than indica rice. https://wikimapia.org/external_link?url=https://www.goldendragon.com.tr/
