Japanese “no vacancy” button emoji meaning

The Japanese "no vacancy" button emoji is a red square with the Japanese kanji character "満" written in white. In Japanese, this character means "full" and is commonly used to show that there is no availability or vacancy in places like hotels, parking lots, or other spaces. The emoji is often used in a literal sense to indicate that something is completely occupied, but it can also have a metaphorical meaning. For example, it might be used to express that a person is fully scheduled or that a situation has reached its limit. This emoji provides a visual way to convey the idea of something being entirely filled or booked.

The Japanese “no vacancy” button emoji was approved in Unicode 6.0 and added in Emoji 1.0, see related proposal L2/09026
