The Japanese name, komejirushi (Japanese: こめじるし; 米印, pronounced [komedʑiꜜɾɯɕi], lit. 'rice symbol'), refers to the symbol's visual similarity to the kanji for "rice" (米).2
In Korean, the symbol's name, chamgopyo (Korean: 참고표; 参考表), simply means "reference mark". Informally, the symbol is often called danggujangpyo (당구장표; lit. 'billiard hall mark'), as it is often used to indicate the presence of pool halls, due to its visual similarity to two crossed cue sticks and four billiard balls.
In Chinese, the symbol is called cānkǎo biāojì (Chinese: 参考标记; lit. 'reference mark') or mǐ xīnghào (Chinese: 米星号; lit. 'rice asterisk' due to its visual similarity to 米 "rice"). It is not often used in Chinese writing.
In Unicode, the symbol has code point U+203B ※ REFERENCE MARK.
