Lake Juliet (ジュリエット・レイク, Juliet Lake) is a location of Another Code: R - A Journey into Lost Memories. It is a camping resort located near the homonymous lake, and home to many past events. JC Valley, the laboratory where Richard Robbins works, is located on shores of Lake Juliet. Lake Juliet is surrounded by the Romeo Mountains.
- The lake and the surrounding mountains are named after Willian Shakespeare's Romeo and Juliet, a tragedy about star-crossed lovers. This ties in, narrative wise, as multiple couples with "star-crossed" histories are tied to the area : Richard & Sayoko, Olivia & Gilbert, Rex & Katie, and Michael & Emily.
