Traveler note
Halloween-themed tanks and daytime performances run during the seasonal programme. The lantern workshop is for elementary-school age and older, on its four announced dates only, with limited places; it is not a daily activity. The night programme is separate: 25 October is for annual-pass holders only, while 31 October also admits general visitors. Both nights require a dedicated night ticket purchased online; a daytime ticket or annual pass alone cannot be used for night entry. No night tickets are sold at the on-site counter or machines, and no shuttle bus operates for the night events. Check the operator's booking links and access information before travelling; live availability is not reported here.
