This article is about a/an set of weapons in Kamen Rider Fourze.

Fourze Modules (フォーゼモジュール Fōze Mojūru) are the armaments that Kamen Rider Fourze equips himself with via Cosmic Energy-infused Astroswitches. There are 40 standard Astroswitches in total, 10 of which each correspond to one of the attachment ports on Kamen Rider Fourze's limbs, known as Module Basements (モジュールベイスメント Mojūru Beisumento).

  • Circle Module Basement (サークルモジュールベイスメント Sākuru Mojūru Beisumento): Right Arm. Circle Astroswitches in nature tend to be close-combat weapons, as well as having the capacity to change Fourze's States if its number is a multiple of 10.
  • Cross Module Basement (クロスモジュールベイスメント Kurosu Mojūru Beisumento): Right Leg. Cross Astroswitches in nature tend to be mid-ranged weaponry.
  • Triangle Module Basement (トライアングルモジュールベイスメント Toraianguru Mojūru Beisumento): Left Leg. Triangle Astroswitches in nature tend to be themed after transport.
  • Square Module Basement (スクエアモジュールベイスメント Sukuea Mojūru Beisumento): Left Arm. Square Astroswitches in nature tend to be battle-support items.

A newly discovered metal known as Astorium (アストリウム< Asutoriumu) is a component in certain Fourze Modules, composing the Rough Spikers of the Chain Array Module and the Spike Module, as well as the Shield Module.

The majority of the Fourze Modules are avaliable in the Fourze Module Change toyline which allows simulation with Kamen Rider Fourze.
