The Nishiura mikan, representing the eastern part of Shizuoka Prefecture, is cultivated in the Nishiura, Uchiura, and Shizuura areas of Numazu City. Among them, “Jutaro Unshu” was discovered by Mr. Jutaro Yamada in Nishiura, Numazu City, in 1975 as a bud mutation of “Aoshima Unshu.” Jutaro mikan are harvested in December and then stored for about two months, which increases their sugar content and flavor, and they are shipped to markets from February to March. Jutaro mikan have gained additional fame for appearing in the popular anime “Love Live! Sunshine!!” and are also shipped in limited quantities in original design cardboard boxes featuring the main character Chika Takami.
