The kanji 海 is a pictographic compound ideogram. It is a combination of two parts: the radical 氵（water - the three-stroke element on the left) and 毎（every or each - on the right), which is a phonetic component that suggests the sound "kai". The 氵radically indicates the meaning is related to water. Therefore, the formation suggests that the character is about water, and specifically related to the sea, where water is always present and everywhere.
