The event will be held over two days: May 23 (Sat) – May 24 (Sun)

As previously announced last month, reservations for admission to “NATURE AQUARIUM GALLERY – Welcome Day 2026” will open this week on Thursday, March 12 at 12:00 PM (JST). Admission will be by advance reservation with designated time slots. Entry times are divided into 30-minute intervals, and the number of visitors allowed in each slot will be limited. We recommend reserving your preferred time as early as possible. There is no strict limit on the length of your stay after entry; however, to help ease congestion, we kindly ask that visits be kept to approximately two hours.
 
As in previous years, the Plants Bazaar will also be held. At the ADA headquarters parking area, we plan to offer items such as WABI-KUSA suitable for summer cultivation, DOOA glass pots, and JUNGLE PLANTS that can be grown in CELL. Please take this opportunity to enjoy the newly created aquatic plant layouts and paludariums, and experience them at your leisure amid the fresh greenery of early summer.
