komejirushi; Japanese asterisk-like symbol (※)
Refers to the ※ symbol, used similarly to an asterisk to mark notes, references, or important points in Japanese text.

A komejirushi (※) is used for the footnote.
重要な項目の前に米印を付けてください。

アスタリスク is the Western asterisk (*), while 米印 specifically refers to the Japanese ※ symbol, which is shaped like a rice grain.
From 米 (こめ, 'rice') + 印 (じるし, 'mark'), because the shape of the ※ symbol resembles a rice grain.
