In June of last year, the “Welcome Day” event held at the Nature Aquarium Gallery at ADA’s Niigata headquarters welcomed more than 700 visitors from across Japan and abroad. In response to many requests for more frequent events, we are pleased to announce that we hold “NATURE AQUARIUM GALLERY – Welcome Day 2026” over two days on May 23 (Sat) and May 24 (Sun), 2026.
To allow guests to enjoy both the event and sightseeing in the Niigata area, admission will be managed through a time-based reservation system. The gallery will feature many aquatic plant layouts and paludariums created specifically for this occasion.
Please visit the Nature Aquarium Gallery in Niigata during the season of fresh greenery before the rainy season begins where time flows gently.
