  • We all enjoyed ourselves, especially our youngest grandson since it was his very first visit. Thank you Ayaka san!  more »
  • The aquarium itself is not big, but there is a long underwater tunnel, and the fish swim swimming in the water tank. There are not many fish in a small aquarium like an aquarium in Japan, so you can see the fish swimming calmly.

  • The entrance fee is a bit costly but the presentation was good for the kids. Their selling point is the longest underwater walk in the world. It was actually a fun walk, i wish i could see more fish. The new area, Mariana Trench does not show fish, instead they show the lessons and learns from their study . The divers were really friendly for my kid.
  • I take my daughter weekly here. We sit in the tunnel for close to an hour each time we visit. She loves it. The staff is friendly and educators on Guam get a free year long pass by presenting their school ID
