"Demon Staircase of Hell"

Phrase used by senior referee Shu Nishinaga and the Noah ring crew 

"The Demon Staircase of Hell" or the "Devil's Staircase" is a name given to the notorious staircase at the Shin Yuri Twenty One Hall, Kanagawa.
The venue does not have a loading bay for the equipment truck, so the ring crew and the trainees have to carry the ring bit by bit from the truck, across the plaza and then down this long staircase and then into the hall and then back again after the event finishes.
Noah normally visit the venue in the summer, so this is usually done in the heat.
