Once the penguins have regained their autonomy (there is no human intervention during the walk), they can interact with their surroundings (including humans) much more proactively.
They are so fun to watch: The Penguin Walk became Asahiyama’s most popular event during winter. (and Asahiyama Zoo became one of the most popular zoos in Japan)
Penguins are also very agile in the water. It’s something you don’t imagine by watching them waddle on the ground. The Asahiyama Zoo’s penguin house is designed so that the visitors can see penguins flying by in the water.
