Comments from GENERATIONS
GENERATIONS is very happy to be collaborating with Sunshine Aquarium this time. An aquarium is a space filled with the excitement and wonder we felt as children, and as adults, it is also a place that brings about new encounters and emotions. There are many similarities with our tour theme this year, "6IX SENSE," and every time we come into contact with the mystery of living creatures and the beauty of nature, it gives us "new sensations and emotions." We hope that we can share this feeling with everyone who comes to the aquarium through this collaboration. The exhibits and experiences incorporate elements that link with our music and the individual personalities of each member, creating a content that allows you to feel the colors and personalities of each of our six members, "6IX COLORS."
We hope you will spend some time with your family, friends, and loved ones to brighten your spirits.
