"I love you" in japanese is "aishiteru" or "aishiteru imasu" (the subject and the direct object are omitted). But you'll hear more often "suki desu" ("I like you") or "daisuki desu" (I like you very much).
Small correction:
"aishiteru" is shortened form of "aishite iru", so you don't need an extra "imasu" at the end. It's either aishiteru (aishite iru) or aishite imasu (more official/polite)
