Komejirushi

The komejirushi (Japanese: こめじるし or 米印) is a punctuation mark, that is used in Japanese and in Korean (known as 참고표). The name literally means "rice symbol", indicating the similarity to the kanji for rice; 米.

It is used to call attention to an important sentence or thought, like a prologue or footnote. In contrast to the European asterisk, it is not used for connecting a specific place in the text directly to the footnote, but rather for notes directly before or after the passage.
