What Is Toppo Day?

October 10th is "Toppo Day" in Japan, established in 2002 by Lotte Co. to promote its chocolate-filled snack "Toppo," inspired by how the product's shape can be represented by the numerals 1 and 0.

A Holiday for a Beloved Snack You Can Enjoy From Either End

"Toppo" is one of Lotte's iconic long-selling snacks, a pretzel-like biscuit stick filled with chocolate.

Origin: the snack's slender shape evokes the numeral "1," while its chocolate-filled tip suggests the roundness of "0"
Purpose: to help more people discover the appeal of the "Toppo" snack
Product highlight: chocolate is packed generously into both ends, a structure that keeps the snack enjoyable to the very last bite

The Fun "Which End Do You Eat First?" Debate

With chocolate filling both ends, "Toppo" often sparks a lighthearted debate over "which end to eat first," turning the snack into a small conversation starter.
