Okinawa Jail, also known as the Cage of Desolation, is a location in Persona 5 Strikers. It is the Jail of Okinawa with Shuzo Ubukata as its Monarch, though he is deceased by the time the Phantom Thieves arrive to investigate.
Manifesting around a facility in Okinawa, the Okinawa Jail is the prototype of all subsequent Jails. It took form from the cognition of Shuzo Ubukata, a researcher performing experiments with the goal of changing hearts, acting under orders from Akira Konoe.
The Monarch ran experiments on changes of hearts in the hopes to realize a utopian dream of completing a Penitentiary System that would end the suffering of mankind, using EMMA as a guide. However, Ubukata would go about using unscrupulous methods to test the extent of what changes of heart would do to a person. Island locals were ordered to eliminate anyone approaching the laboratory without clearance in order to test a change of heart's ability to facilitate complex commands and whether their own personal morals would override such commands. Scientific staff that objected to the experiments or tried to report the research would become subjects of the experiments themselves. Ubukata would justify the use of human experimentation as following orders and needing to be able to manipulate the cognitive world themselves after hearing of another party manipulating the cognitive world for their own purposes, not wanting the other party to progress beyond them and waiting to attain the ideal society.
Only too late did Ubukata learn that he would be required to hand over his own Desires as well, and that the Penitentiary System wasn't actually meant to save humanity. That the secret purpose of the project was to simply turn all of humanity into slaves. Faced with the fact that his Desires would be seized at any moment, Ubukata would pitch himself over a cliff near the facility, killing himself in an attempt to stop the Penitentiary System from being realized. The Jail fell dormant with the loss of its Monarch, though the locals remained brainwashed.
Some time later, on August 17, the Phantom Thieves arrived at the island. Asking about and approaching the lab drew the ire of the locals, who became a murderous mob that night. The Thieves escaped thanks to Zenkichi Hasegawa picking up on their strange behavior, and later attacked a local man and looked through his phone to find the Jail's Monarch and keyword. After entering it, the jail awakened and EMMA admitted passage.
Records of the experiments at the facility manifest in the form of notes and tape recordings inside the Jail, detailing the events of what happened there. Sophia also hears a mysterious, familiar voice shortly after entering, and runs ahead on her own in an attempt to locate it.
Once the Phantom Thieves help Sophia reach the depths of the facility, they enter the Cage of Desolation, where they find the Desires suspended from the ceiling, still solidified from the warning that Ubukata received. The mysterious voice will speak directly to Sophia, inquiring of her purpose and parameters, but when Sophia is unable to answer the voice summarily labels her as worthless. After Ryuji becomes enraged at this and berates the voice, it will cease communication, activating its security in the form of a Lock Keeper that attacks the party. Following the defeat of the Lock Keeper, the cage will collapse, leading to the party needing to evacuate the area.
