Daitenku Temple

The Daitenku Temple (大天空寺 Daitenkūji, lit. Great Sky Temple) is a monastery with a basement-based research laboratory for Kamen Rider Ghost's allies (namely Sennin) to live in. [1]

After the first few Gamma attacks, Onari decides to make the temple into a paranormal investigations office, Mysterious Phenomenon Institute, to better aid in Takeru's quest to find the Ghost Eyecons and stop the Gamma by having citizens around the city report strange events to them.
