In addition to the said 18 statues, more statues will be installed later this year, namely Kikaider's enemy, Hakaider and Kamen Rider 1 with his motorcycle, Cyclone. Said Kamen Rider 1 statue will be installed in the middle of the city. Lastly, the city hopes to add more AR attractions within the city and even plans to add 3 more bronze statues. There are even hopes to turn the entire city into a "manga museum."
