The biggest highlight of the aquarium is its reputedly largest tank in northeastern Japan, showcasing the marine life of the region. The entire wall of flowing blue water features various fish swimming gracefully, creating a serene atmosphere perfect for quiet contemplation.

At regular intervals, the sardine show takes center stage, where a large group of sardines swirl and dance in the tank, creating a “Sardine Tornado” in the water – a spectacular sight not to be missed.

4. The Sea Lion Touch Experience
At regular intervals, the aquarium brings out adorable sea lions for outdoor interaction, allowing visitors to get up close, even touch and take photos with them. However, the Sendai Ocean Forest Aquarium reminds guests that touching the sea lions requires prior disinfection, and only the back should be gently stroked – never the head, to avoid startling them.
