Botan Rice Candy is a specific brand of a category of Japanese candy called bontan ame . Bontan ame are soft, chewy, citrus-flavored candy with an outer layer of rice paper or Oblaat. The rice paper is clear and plastic-like when dry, but it is edible and dissolves in the mouth. This candy was invented by Seika Foods in 1924. During this period, more and more Western-style sweets were becoming popular in Japanese society, and the appearance of this type of candy is intentionally similar to Western-style caramel candies. In Japan, these candies are sold as Dagashi, cheap candies and snacks marketed to Japanese schoolchildren, and are often in small sizes with bright colorful packaging with stickers or prizes included.
Bontan (ボンタン) is a variant spelling of buntan (ブンタン), the Japanese word for Pomelo, which is commonly used as a flavor.
