For this June 15 slot at ZUBAR, the flyer evidence clearly gives a 05:00 open/start and a 500 yen entry. The dawn-time kickoff is the event’s strongest identifiable feature. The lineup is not recoverable, but the timing suggests a niche gathering with a committed, off-hour crowd. This is mainly for people drawn to unusual early-morning sessions.

ConceptA sparse but distinctive early-morning event where the 05:00 start and 500 yen entry are the main draw.
