Mite or small arachnid; possibly a variant of Akari.
In a scientific context, Acari is the Latin taxon for mites and ticks. As a given name, it is extremely rare in the West and may be used as a creative variant of the Japanese name Akari, which means 'light' or 'brightness', or as a modern invented name.
About 13 boys were named Acari in 2025.
