"Moon Water" is a song recorded by Japanese singer Shizuka Kudo, from her tenth studio album, Purple.

When Kudo appeared on the AX tanpatsu drama Ren'ai Zenya: Ichido Dake 2 (1996) as a drawing-class model, the artwork she was the subject of is revealed to be a direct replication of the "Moon Water" cover art.

The single's B-side, "Still Water", is a song created around the same demo track but with different lyrics and arrangement.

[4] "Moon Water" became Kudo's first single to not reach the top ten since her solo debut.
