The Transformation Belt Ziku-Driver (変身ベルト ジクウドライバー Henshin Beruto Jikū Doraibā, lit. "Spacetime Driver") [2] is the transformation device used by Kamen Rider Zi-O, Kamen Rider Geiz, Kamen Rider Tsukuyomi, Kamen Rider Barlckxs, Kamen Rider Zonjis and Kamen Rider Zamonas. It uses Ridewatches as its primary collectible device.[3]


The Ziku-Driver is composed of the following parts:

  • The D '9 Slot (D‘9スロット D ‘9 Surotto) is the right-hand slot for inserting transformation Ridewatches.
  • The D '3 Slot (D‘3スロット D ‘3 Surotto) is the left-hand slot for inserting Ridewatches to access Rider Armors.
  • The Ride On Ruser (ライドオンリューザー Raido On Ryūzā) is a button which unlocks the Ziku Circular and the approval key of each Ridewatch that was inserted.
  • The Ziku Circular (ジクウサーキュラー Jikū Sākyurā) is the main unit of the Ziku Driver. By rotating it 360 degrees, it spreads and loads the data of the Ridewatches set into the slots at both ends into concentric circles and transfers it to the Ziku Matrix. The energy generated by its rotary motion that is accelerated and amplified for use in transformation and finishers.
  • The Ziku Matrix (ジクウマトリクス Jikū Matorikusu) is the theoretical realization device of the Ziku Driver located behind the Ziku Circular. It realizes the data of the inserted Ridewatches, transmitted by the Ziku Circular, as equipment and armor.
  • The Sight Window (ザイトウインドー Zaito Uindō) is the display of the Ziku Driver. In addition to the time coordinates of Ridewatches, the Rider's current form is also displayed.



To transform, the user inserts the Ridewatch into the D '9 Slot before pressing the Ride On Ruser and rotating the Ziku Circular 360 degrees. To assume a Rider Armor form, the user inserts a second Ridewatch into the D '3 Slot and performs the same procedure.

The Decade Ridewatch accesses additional forms through inserting another Ridewatch into it, without needing to rotate the Ziku Circular. Upgraded forms either use a Ridewatch that takes up both slots, or have a secondary Ridewatch inserted in the D '3 Slot while still using the base form Ridewatch.


To activate a finisher, the user presses the Ride On Starter on any Ridewatches inserted into the Ziku Driver before pressing the Ride On Ruser and rotating the Ziku Circular 360 degrees.

Behind The Scenes


The prose segments of the Ziku-Driver's announcements are voiced by Rikiya Koyama (小山 力也 Koyama Rikiya), who also voiced Ohma Zi-O and previously voiced Paradox Roidmude in Kamen Rider Drive: Surprise Future, Kamen Rider Bujin Gaim in Kamen Rider × Kamen Rider Gaim & Wizard: The Fateful Sengoku Movie Battle, and physically portrayed Joe the Haze in Kamen Rider Black RX.

The vocal segments of the Ziku-Driver's announcements are voiced by Yohei Onishi (大西 洋平 Ōnishi Yōhei).[4]


  • While the Ziku-Driver is mainly based on the word for "space-time" (時空 Jikū), it can follow Zi-O's secondary theming of Japanese lettering with the Japanese word for "lettering" (字句 Jiku).
  • As the DX Ziku-Driver utilizes the same pin system as the DX Build Driver, it is possible to activate its different displays by using DX Fullbottles.
  • The Ziku-Driver is based on wrist watches.
  • After a Rider transforms using the Ziku-Driver the screen on the Driver shows the year of the Rider whose power they are using or of their own power this might represent a clock going ahead or back in time.
    • The transformation special effect with big clocks in the background and rotating circles around the user is very similar to two past Kamen Riders: Kamen Rider Cronus and Kamen Rider Evol.
      • Coincidentally, Cronus is a Kamen Rider who also possesses time-manipulation abilities.
    • In-show, the year stays visible on the Driver, however in the DX Driver, the year simply disappears after.


  • The battery slot cover of the DX toy has the katakana for "belt" (ベルト Beruto) on it.
    • While this makes sense for Zi-O's katakana motif, it would clash against Geiz's Hiragana motif (i.e. the katakana for "belt" should be written in all hiragana (べると)).
      • This might have been due to the fact that the Driver that Geiz uses was stolen from Ohma Zi-O in the future timeline, as revealed during the thirteenth episode of Zi-O. Ghost Hunter 2018
  • In the Korean release of the Ziku-Driver, it is renamed Time-Driver .
