The kanji 昇 is a phono-semantic compound (形声文字). The left side is a part of 日（にち） meaning "sun" or "day", and the right side is 升（しょう） which represents a measuring container, but also acts as a phonetic component here, contributing the sound ショウ（shou). The original meaning was likely connected to the rising of the sun. The combination of 日 and 升 therefore suggests the sun ascending, thus giving the kanji its meaning of "rise" or "ascend."
