This article is about a/an device in Kamen Rider Fourze.

The Astroswitch Kaban (アストロスイッチカバン, Asutorosuitchi Kaban) is a special briefcase that resembles a Japanese schoolbag made to hold the Astroswitches and used by Kengo Utahoshi.

The case can hold up to twelve Astroswitches, but despite its name, it is no mere case. The Astro Switch Kaban can act as a portable terminal with various functions, such as collecting data from the Foodroids (mainly Burgermeal), performing Zodiarts analysis, and communicating with the Rabbit Hatch. It also has an alarm system to alert of Zodiarts presence.

The case also has a vehicle operating panel for both the Powerdizer and the Machine Massigler.

When Fourze used Cosmic States for the first time, Kengo had to open the case to release the Switches to be absorbed into the Fourze Suit.
