If you are looking for a place to explore but is not overcrowded, come here. The dolphin shows are great! You'll probably see animals you have't seen before. There's even a lovely ajisai park.
I went here for the Persona 30 anniversary collab and it did not disappoint! I enjoyed every little moments. There are frequent school trips during the week day so be prepared for influx of children
I brought night pass and arrived from 5pm, play til 730pm to avoid the hot weather. Played 6 times of games and aquarium. I drived, park in car park c then walk to the island, it takes around less than 10 minutes.
Was ok. Went to the osaka aquarium sith the huge tank and whale sharks and this one didnt really match up. There is a live dolphin show that was good but as a whole its kinda a small aquarium.
