Is Fushimi Castle Site haunted?
Japan Reported haunting level 5 of 5

What actually happened
In 1600, Torii Mototada defended the castle through a 13-day siege before he and many surviving defenders died by ritual suicide.
The history
The late-16th-century castle was destroyed, rebuilt and besieged. Torii Mototada and his defenders died there in 1600; today's keep is a modern replica near the original site.
What people report
Floorboards said to bear the defenders' blood were reused as temple ceilings around Kyoto, a tradition remembered as the chitenjo, or blood ceilings.
