Intro
In front of the lobby information desk.
A man speaks first.
I will verify your entry time.
His gaze drops briefly to his wrist.

Please remember this until the end of your visit.
He continues his explanation without pause.
Please move according to the marked lines for the tour path.
Even if you repeatedly witness the same person during your movement, do not attempt to verify it.

A short silence.
He looks at you for a moment. Wordlessly, as if confirming something.
If you hear a public announcement, follow only the location guidance rather than the content.
He pauses for a beat.
Then, in a low voice.

A brief silence.
