AT 3:15 a.m., a local resident alerted emergency services about the two bodies collapsed in a parking lot of the hotel, located in the Takasago area.
Officers from the Chuo Police Station arriving at the scene confirmed the man and woman, both adults, dead at the scene. They are both believed to have been guests at the hotel, police said.
Police believe the couple leaped to their deaths from a seventh-floor emergency staircase of the hotel. A chair was found propped on a landing of the staircase on that floor.
Police are now working to confirm their identities.
