  • 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.

  • It was perfect for the daughter who liked sharks. It was so full of sharks that there were only sharks and ei. I just made it a course to watch, but i thought it was better to have an experience type.

  • 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
  • Great and awesome staff. Very friendly and very helpful. Great place to take the kids. And great for adults too!
  • When I lived in Guam Underwater World was one of few underwater tunnel aquariums I had ever seen. It held the record for the longest in the world I think. They have some of the coolest fish, sharks, turtles, and rays you could imagine. It is well worth a visit if you are in Guam.
  • The dive tour looks coool!!! Awesome aquarium, and a sea food dinner in the tunnel is an experience you won't get anywhere else on the island. Great choice for date night.
