Swiss Family Treehouse is a walk-through exhibit in Adventureland at Tokyo Disneyland. It's worth seeing on a time-permitting basis.
The Swiss Family Treehouse opened at Tokyo Disneyland in 1993, 10 years after the park's debut. You'll climb up, then down, several hundred steps, one-way, through this artificial tree, exploring the various rooms of the castaways' treehouse, inspired by the 1960 Walt Disney Pictures film.
