Aquamarine Fukushima

Shiome-no-Umi tank timing: The Kuroshio tank has scheduled feeding demonstrations (11:00 and 15:00, 20 minutes) when divers hand-feed bonito and sardines, creating swirling bait balls visible through the 9-meter-wide viewing window. Arrive 10 minutes early for front-row positioning. The feeding triggers hunting behavior — watching tuna accelerate to 60 km/h in short bursts provides rare insight into pelagic predator dynamics. This is one of few aquariums globally exhibiting Pacific bluefin tuna (endangered species, difficult to maintain in captivity).

Interactive zones: The touch pools (Ground Floor, Aquamarine Passage) allow handling starfish, sea cucumbers, horseshoe crabs, and small sharks under staff supervision. The most unique interactive is the transparent floor section where visitors walk over seal tanks — seals swim directly beneath your feet, creating disorienting perspective. The Janome Beach (rooftop) is a recreated tide pool ecosystem where visitors can wade ankle-deep (free loaner boots) and observe hermit crabs, small fish, and sea anemones — excellent for children and educational for understanding intertidal ecology.

Post-tsunami context: The 2011 Tohoku tsunami inundated Aquamarine with 4-meter waves, killing 90% of animals and destroying exhibits. The facility reopened in 2012 after intensive rebuilding and restocking. Several exhibits specifically address tsunami ecology — how marine ecosystems recover, debris rafting species (organisms that crossed the Pacific on tsunami debris), and sustainable reconstruction. The resilience narrative adds emotional weight to the visit — this is not merely entertainment but a symbol of Fukushima's coastal recovery. Consider this context when visiting.
