Which emoji is commonly used to represent the Japanese flag?

The emoji commonly used to represent the Japanese flag is 🇯🇵.

This flag emoji is built from the regional indicator symbols for the country-code pair JP. The pair corresponds to Japan under the two-letter ISO 3166-1 alpha-2 country-code system. Unicode does not encode every national flag as a separate indivisible character; instead, many flag emoji are generated from regional-indicator sequences.

The Japanese flag itself is a white field with a red disc, representing the sun. On supported devices, the regional-indicator sequence is rendered as a single flag-style emoji. Unsupported systems may show two letter-like regional indicators instead.

Flag emoji can also represent territories and subdivisions, and platform support is not identical everywhere. The code pair is the reliable underlying reference, while the visible artwork depends on the font or application. Japan’s flag emoji should not be confused with the flags of China, South Korea, or Palau, which have different regional-indicator pairs.
