Janjira

Janjira is a fictional Japanese city near Tokyo with a nuclear power plant located inside it.

In 1999, after the discovery of the two MUTO 'spores', the hatched male MUTO burrowed to Janjira, the nearest source of radiation. Joe Brody and Sandra Brody worked at Janjira at the time, after moving to Japan for better jobs. When the MUTO started causing seismic anomalies underneath the city of Janjira, Joe and Sandra Brody were at work in the plant. Thinking it was a regular Earthquake, the staff at the Nuclear Power Plant began to switch off the systems to prevent damage. The MUTO suddenly began to feed, causing the reactors to rupture, spewing out their radiation-contaminated water. This resulted in the deaths of Sandra Brody and her team in the trapped with the reactor. The plant then collapsed under the strain of the MUTO feeding, causing more casualties. The MUTO then cocooned to continue feeding on the radiation which was released, as Monarch took the plant and the city of Janjira under quarantine.

In 2014, Joe and Ford Brody managed to bypass the quarantine zone's security and found much of the city slowly returning to nature, being infiltrated by plants native to the surrounding area. There, Joe managed to recover floppy disks on the reactor collapse and found that strangely, the radiation levels in the city were at normal, background levels (later found out to be due to the MUTO's feeding). The two were then captured by Monarch security. Joe and Ford Brody were taken to the Janjira power plant and Joe was interrogated. The MUTO then abruptly hatched from his cocoon, and mortally wounded Joe. It also killed hundreds of Monarch workers as it fought its way out of its containment. The MUTO escaped the plant soon after.
