Splash Mountain at Tokyo Disneyland will be closed from February 12 to March 19 according to the Tokyo Disneyland refurbishment schedule.
Splash Mountain Refurbishment

While Splash Mountain in Walt Disney World and Disneyland have been re-themed and re-named as Tiana’s Bayou Adventure, there are no plans to overhaul the storyline for Tokyo Disneyland Splash Mountain. Re-theming in the U.S. parks provided distance from the controversial “Song of the South” animated film that was the basis for Splash Mountain.

Tokyo Disney Resort is owned and operated by the Oriental Land Company which licenses intellectual property from the Walt Disney Company. Tokyo Disneyland opened in 1983 and added Splash Mountain to the attraction list in 1992.
Attractions are regularly closed for maintenance periods to refurbish ride displays, repair mechanical issues and ensure that all safety solutions are functioning properly.
