According to police reports, officers were dispatched after receiving alerts from passers-by about a man perched on a roadside barrier on the terminal’s fourth floor on Tuesday afternoon, Dimsum Daily reported.
Upon arrival, authorities found the man suspended from the barrier, clinging to the building’s edge, Tokyo Weekender reported.
Paramedics transported him to a nearby medical facility, where he was later pronounced dead.
Initial investigations indicate the deceased was a Chinese tourist visiting Japan with his mother.
