I saw the show in Japan. I was under the impression that The Little Mermaid is closing this April (I could be wrong). It is the same version as The Netherlands and more similar to the new North American tour/Papermill Playhouse rather than the Broadway version. The biggest differences are the use of flying in this production is a lot more gimmicky (but gorgeous) than Broadway's and this version replaced the song "I want the good times back" with "Daddy's Little Angel".
While you're there seeing Shiki shows, I would also recommend The Hunchback of Notre Dame, since it is also an amazing show :)
