ESCAPE Inc. has launched the first round of the “Chiikawa Search Campaign” in Tokyo, inviting participants to join a fun photo challenge inside Tokyo Metro stations. The campaign encourages fans to find special “Chiikawa, Sagashitemasu” posters displayed throughout Tokyo Metro stations. It’s a convenient activity for those already traveling around the Tokyo Metro network.
To enter, participants must photograph the campaign posters and post the images on X (formerly Twitter) with two hashtags. Fifteen winners will be randomly selected to receive a “Chiikawa Search” escape game play kit at no cost.
About the Campaign

This campaign is part of the “Chiikawa, Sagashitemasu. ‘Movie Chiikawa’ Tokyo Metro Escape Game,” a collaboration tied to the movie “Chiikawa: The Secret of Mermaid Island,” which opened on July 24, 2026.

The immersive game lets participants search for missing characters Chiikawa, Hachiwara, and Usagi, experiencing the movie’s world firsthand.
