Yokohama Hakkeijima Sea Paradise is filled with a variety of different aquatic animals as well as various cute land animals.
There are live shows available throughout the day at scheduled times, which are listed on their website. The live performances were captivating and I enjoyed the dolphins’ performance the most.
Apart from the massive aquariums, Yokohama Hakkeijima Sea Paradise also has various attractions and rides such as a roller coaster ride (The Leviathan), a boat ride, fishing spots where you can catch and cook your own fish as well as fish farms. The roller coaster was absolutely scary, it had multiple drops and loops. Although it was fun, we queued about 40 minutes for the roller coaster.
There is a food court with various lunch options including fast food. Relatively cheap and filling. There is also a souvenir shop however the products were on the pricier side.
I highly recommend anyone visiting to book the tickets in advance as the queues for purchasing tickets on-site that day were very long. Fortunately for us, we booked the day pass in advance on Klook so we were able to enter the aquarium almost immediately.
The day pass includes free entry to almost all rides and attractions excluding some like the haunted house. We spent the entire day in Yokohama Sea Paradise and still felt that we haven’t seen everything. Overall, it’s definitely a place worth visiting.

Some amazing animals on display and good variety of exhibits and performances.
The shows are all done in Japanese so bit hard to follow if you're an English speaker.
But the facility is looking old/tired and one of the 4 aquariums was not worth a visit (Umi Farm).8
The Leviathan roller coaster was also good but you need to buy tickets at the Aqua Museum before you go to the coaster.
Easy to get to via public transport.
I don't know if it's because it was winter or what, but it was surprisingly quiet! I took my partner here for the P3 collab, because he really likes the game, and we had a really good time! The stamps take you through all the important spots, and there was quite a lot to do. Unfortunately, there were quite a lot of things (the rollar coaster, the cruise, etc) that were closed while we were there for maintenance or due to "bad weather", which is a shame but I guess it can't be helped, maintenance needs to be done some time. Still had an excellent day out.
I will also say I was a little confused about the correct entrance, as I was expecting there to be admission, but apparently you can just walk in, and the tickets are just for the attractions, so that was pretty cool. Did mean we got a bit lost trying to find the "correct" route in though!
I arrived here at the entrance of the Aqua Museum (aquarium) around 8:50am on a Saturday morning. My friends and I bought tickets on Klook with a 9am arrival. There was a line but they let people in around 8:55am. If you don’t already have tickets, there is a ticket booth. Staff have print outs of common questions/information in English that aids with communication barrier. We didn’t know this was part of an amusement park, so that was a surprise.
Upon entering, we passed aquarium tanks with fish. Beyond that is a place to have pictures taken for an additional cost.
They have many animals including penguins, sea lions, large crabs, polar bears, walrus, sharks, jelly fish, sting rays, eels, and many, many more! They have an outside area for land animals such as otters, flamingos, and prairie dogs. You even get to go up the escalator through one exhibit, which is pretty cool. In lab 6, you can touch and hold a starfish.
My biggest complaint is that they need to clean the windows in the water exhibits because the parts where there isn’t water is obstructed, which prevents guests from seeing the animals clearly. There was one exhibit with bubbles and what not on the lid where we couldn’t see at all inside.
We watched a live presentation at 10am. The visuals had English translation, which was great. There was dolphins, penguins, and walrus in the show! Unfortunately, the commentary was in Japanese, so we didn’t understand it. The show lasted about 25 minutes.
They have vending machines throughout the aquarium but they take cash :( I noticed they had spaces for breastfeeding women, which is cool!
After we finished the aquarium, we went to the food court and had lunch. I got a burger, fries, and chicken nuggets, which was good. The burger had a mozzarella type cheese on it that I thought was mayo. It was overpowering and I didn’t finish it. My friends got ramen and food from the chicken place and they enjoyed it! It’s fair prices, much better than food at an amusement park in the USA, lol.
My friend wanted to ride the roller coaster, which we did. We had to go back to the ticket counter to purchase the ticket. If you’re a local, you can purchase online. I like that you can buy tickets to an individual ride but they do have various day passes.
Overall, it was a fun experience! We were there for about 4 hours. They have a gift shop and MANY food and dessert options outside of the food court. I would return!

We really had a great time here as you can see in the pictures, wish we had all day to explore. It's amazing so many to see, our advice start in the line before they open and stay until close. Y'all definitely will enjoy your tour, each show is so amazing.
