I’d say the Japanese had the fascination with mermaids steam from the old fishemen’s tale of the nyngyo but in the case of Yasuhiro Aoki’s ChaO, this is more reminescent of the old American romantic comedy Splash by Ron Howard, not a direct remake but still about a man that finds himself engaged to a mermaid that saved his life, though here he doesn’t remember doing so, yet is pushed into being the fianceè and husband-to-be of the mermaid princess Chao, as the situation is favorable to the man’s boss, a transportation mogul, despite initially being kinda put off by Chao’s out-of-water appearance of a bipedal fish.

I’d say the main issue is that the plot is fairly thin and predictable, but the movie is definitely aware and Yasuhiro Aoki instead decides to focus on the love story AND in delivering insanely creative visuals, with deliberately weird, off-kilter character designs, not just relegated to the magical sea creatures just living alongside humans, but the humans themselves already have a distinct design even when they are regularly proportioned, and aren’t just giant toddlers, have giant heads or spherical bodies, or weird elongated limbs.

It’s very visually striking and interesting, definitely helps to have Hiroshi Takiguchi (also behind many Shinkai films) as the creative director here too, and animation studio 4°C help deliver the remarkable extreme sensory overload that goes along an otherwise very nice, very sweet but predictable romance, most likely because they know the romance itself is fine but not original (despite the political undertones since the marriage is basically sold as a public “race relation PR stunt”), and hence could use some great visuals, even some cool actions scenes and a fitting bonkers direction to go along with it.

Definitely worth seeing, even more as it just 90 minutes.
