Guidelines

Fixed Show Schedule: Unlike a museum, you cannot enter at any time; public shows typically run at specific times (often 10:00 AM and 2:00 PM), so it is crucial to check the daily schedule beforehand. Ticket Purchase: Tickets must be bought at the entrance gate on a first-come, first-served basis, and it is highly recommended to arrive at least 30–45 minutes before a show starts as they frequently sell out, especially on weekends. School Group Priority: During weekdays, morning shows are often reserved for large school groups, so independent travelers are advised to aim for afternoon slots or Saturday shows.
