Communication (from Latin communicare, meaning "to share") is the purposeful activity of information exchange between two or more participants in order to convey or receive the intended meanings through a shared system of signs and semiotic rules. The basic steps of communication are the forming of communicative intent, message composition, message encoding, transmission of signal, reception of signal, message decoding and finally interpretation of the message by the recipient.

"Communication" is Hitomi Takahashi's 4th single under the Sony Records (gr8! records) label. The single was released in only one format on July 12, 2006, nearly eight months after her last single Aozora no NAMIDA.

Dizon herself also wrote or co-wrote 10 of the tracks, along with composing 2 herself.
