Rabbit Hutch
The in-show material spells it "Rabbit Hatch", which doesn't make any sense since their base isn't underground. Plus rabbits live in hutches. The Japanese pronunciation for hatch/hutch is exactly the same, which is probably where this error came from.
The hero's secret base on Kamen Rider Fourze. Using the power of Kengo's Switch, they are able to go from a storage room in Amanogawa High to the base on the moon surface. At first, it is just Kengo and Yuuki's private hideaway but as the series progressed, it became the main bas of operation for the Kamen Rider Club.
Each member has their own space. The area is decorated with their private goods.
In episode 48, Sagittarius Zodiarts and Leo Zodiarts destroy the Rabbit Hutch.
Corrected Spelling
In the Kamen Rider Fourze Astro Switch Secret Report DVD, Rabbit Hutch is spelled correctly on the monitor.[1]
