Opening & visit notes
- Closed Tuesdays except in August. A holiday Tuesday opens, with the next weekday closed. New Year closure is 29 December–4 January. The official monthly calendar also confirms continuous closure from 29 December 2026 through 5 January 2027.
- For 23 February 2027, a holiday Tuesday, the regular holiday-opening rule conflicts with the current monthly calendar’s closure marking. Confirm opening on 23–24 February directly with the park.
- The trolley normally runs on weekends/public holidays in March–November and during August’s Obon period. Its regular December–February suspension does not mean the whole park closes for winter.
- Much of the collection is outdoors. Bring winter layers and suitable shoes, and check official notices for weather or maintenance changes to rides.
