This article is about a/an ally in Kamen Rider Zi-O.

Junichiro Tokiwa (常磐 順一郎 Tokiwa Junichirō) is the great uncle of Sougo Tokiwa and owner of 9 5 DO.


In 2009, Junichiro visited a hospitalized Sougo after he survived a tragic bus crash resulting in the death of the latter's parents. To comfort the boy, he offered that he come live with him once discharged, to his joy. GeizRevive! 2019

In early September 2018, Junichiro began renting a vacant room on the second floor for the use of Tsukuyomi and Geiz Myoukouin, who came from the year 2068 to investigate Sougo's potential to become the tyrant Ohma Zi-O. Later Black Woz also rent another vacant room after the incident with Geiz Revive.

He is initially unaware of Sougo's identity as a Kamen Rider as well as Geiz, Tsukuyomi, and Woz being from the future, until later.  Best Match 2017


Much like his great-nephew, Junichiro is shown to have an optimistic outlook on life and is often seen with a welcoming smile. He is also shown to be very hospitable, gladly allowing Geiz, Tsukuyomi, and later Black Woz to stay as tenants at the 9 5 DO. This hospitality is also seen when he repairs any electronics his clients bring to him, albeit somewhat reluctantly. He also appears to be quite knowledgeable, often giving words of wisdom. and cooking foods for them.

Junichiro also deeply cares for his great-nephew and wants him to be happy. However since Sougo's parents passed away, Junichiro has been feeling insecure about scolding Sougo, as he was all alone and didn't want to negatively impact their relationship. However, when he finally does so, he ends up reeling in fear over what he just did. Junichiro is also very empathetic and sees that since Tsukuyomi and Geiz left, Sougo was left all alone again. Junichiro encouraged Sougo to be more upfront and honest with his feelings, as a king needs to have empathy for others. He is also very supportive of any activity that Sougo decides to take up towards his kingship, and proudly wished him great luck and safety upon discovering his nephew's identity as a superhero.

His immense care for Sougo is also taken to a more humorous standpoint, especially with food. When preparing rice balls for evacuating the massive meteor soon to hit Tokyo, he decided to prepare an entire rice sack's worth of rice balls (ended up preparing eighty, as opposed to the original seven) when he found out Sougo was returning from space, believing he didn't make enough and that Sougo must be starving.



  • Horology: Junichiro is skilled enough at fixing timepieces that he is able to open a shop and make a profit out of it.
  • Cooking: Junichiro has been shown to cook at a level that would even impress a professional like Shouichi Tsugami. He is known to cook a large variety of foods, including traditional Japanese cuisine, foreign fine dining, and other pastries.
  • Super Mechanic Ability: While Junichiro can repair a lot of mechanical objects, Junichiro can somehow perform some sort of repairs on objects related to Rider Systems, like the Zi-O Ridewatch II (Real World), DenLiner, and even disabled Heisei Ridewatches. According to the Taros and Junichiro himself, he can only interfere with any Rider System if it functions like a watch. Mirror World 20192007: DenLiner Crash!2019: Apocalypse

Behind the Scenes


Junichiro Tokiwa is portrayed by Katsuhisa Namase (生瀬 勝久 Namase Katsuhisa).


  • Junichiro is similar to Eijiro Hikari from Kamen Rider Decade as both are business owners who receive requests from other customers that do not have any relationship with their main business, yet they still do so.
    • In Eijiro's case, many people walk into his photo studio, commonly mistaking it as a coffee shop or a hospital, yet he will still serve a meal or patch them up.
    • In Junichiro's case, many people walk into his clock shop looking to get non-clock items fixed, yet he will still make an effort to fix them regardless. He also serves a meal to the guests.
  • Though confirmed to be unaware of Sougo's identity as a Kamen Rider until episode 48, it was heavily implied that Junichiro had some thoughts about it.
    • Many guests arrive at his shop as "friends" of Sougo, though he never had any before.
    • Geiz conspicuously carries his Ridewatches on his Ridewatch Holder.
    • The Ridewatch Daizer is out in the open with Ridewatches being summoned and locked in front of him.2019: Vanishing Watches Junichiro takes great notice of the destabilizing Ridewatches in Episode 47.
    • Sougo and Geiz discuss their Rider activities fairly openly, though Woz will sometimes have him walk out of the room so they can discuss "sensitive" information.
    • Being asked by Woz to patch up the white half of the Zi-O Ridewatch II, although he wasn't able to completely repair it. Mirror World 2019
    • Sougo's birthday cake had all of his Ridewatches placed on it. 2019: Heisei Oni, Reiwa Oni
    • Woz carries the Oma Advent Calendar with him all the time and calls Sougo his "Demon King" in front of Junichiro, though he would get confused with the word "Demon".
    • When Junichiro was saved by Kamen Rider Zi-O in Episode 48, Sougo's name was the first he shouted out before the latter had formally revealed his identity.
