"Some Ghosts will leave EMF traces near them that will show up on an EMF Reader as level 5."

The EMF reader is a purchasable piece of equipment used to read the strength of electromagnetic fields in the nearby environment.

The EMF reader is used to detect evidence of EMF Level 5.


The EMF reader is a small black box adorned with five colored LED lights, each one indicating a different EMF level. The reader can be toggled on to begin reading any emissions.

If the EMF reader is within ~1.5 metres of an EMF emission, the reader will light up various numbers of its LEDs. If multiple EMF emissions are in range, the one with the highest EMF level will be indicated by the reader. During hunts or when the ghost manifests, EMF readers within 10 metres of the ghost (or higher for a Raiju) will malfunction and display random values between level 1 and 4.

Holding an active EMF reader within 9 metres of a ghost (or 2 metres for a Yokai) during a hunt on the same floor will attract the ghost.

EMF Level 5

If the ghost has EMF Level 5 as a possible piece of evidence, each EMF occurrence of Levels 2 or 3 has a 25% chance to trigger a Level 5 indication instead. EMF Level 5 does not necessarily indicate strong activity or immediate danger to the player.


  • If players are looking for evidence of EMF Level 5, players should use the reader every time the ghost touches an object or surface, and within the 20 second period that the EMF will be active for.
