Traveler note
An after-hours aquarium puzzle walk with three difficulty levels, starting at upper-elementary-school level; allow about two to three hours. Elementary-school pupils and younger must join with a guardian. Each night has a capacity of 700, but remaining places are not reported here. All guests exchange their event tickets at the ticket counter; ordinary daytime tickets cannot be used for admission or re-entry, and other discounts do not apply. Advance sales close at 23:59 on 13 November for the first night and 21 November for the second. Same-day online sales are planned only if capacity remains: kit-included tickets cost ¥100 more, while no-kit tickets retain the advance price. Same-day tickets are not sold at the counter. A separate puzzle kit may be sold inside from 17:30 to 20:00 for ¥1,000, subject to stock; this is not an admission ticket. Annual-pass holders must bring their valid pass, and pass purchase, renewal and issue must be completed by 16:00 before the night session. General parking can be used, but there is no event shuttle bus; arrange your return journey. The photo shows the aquarium exterior in July 2015, not these 2026 night sessions. The official announcement does not confirm English-language puzzle provision.
