Hokkaido Aquarium Map

Every aquarium in Hokkaido, ranked and placed on the map — all 14 of them, from the big names to the local tanks.

1HokkaidoNoboribetsu Marine Park NixeOne of Hokkaido's largest aquariums, uniquely housed within a recreation of a Danish Renaissance castle.Beyond the medieval facade of Nixe Castle, you’ll find a massive four-story aquarium featuring a stunning 8-meter crystal tower and long underwater tunnels. The park’s most beloved attraction is the year-round penguin parade, where King Penguins waddle through the grounds right in front of visitors.Modeled specifically after Denmark’s Egeskov Castle, this theme park blends Scandinavian architecture with marine biodiversity. A standout feature is the 'Milky Way' sardine performance, where 10,000 fish move in synchronized harmony to orchestral music and color-changing lights. For a more surreal experience, the 'Galaxy of Jellyfish' uses floor-to-ceiling mirrors and artistic lighting to create an infinite, glowing void. Outside the main castle, the park features a 'Seal Ring Pool'—a vertical glass cylinder that allows you to watch harbor seals swim directly above and below you. Unlike the more sprawling coastal aquariums in Japan, Nixe offers a highly concentrated experience where you are never more than a few feet away from the action. It is also exceptionally convenient for rail travelers, located just a five-minute walk from JR Noboribetsu Station. This makes it an ideal stop for families or photography enthusiasts before taking the bus up to the nearby hot spring resorts. Pro tip: Check the performance schedule immediately upon entry, as the sea lion and dolphin shows are timed to allow you to loop through the entire park without missing a single event.View on Traveldoko
2HokkaidoOtaru AquariumA seaside aquarium where marine animals live in enclosures carved directly from the natural coastline.Beyond the main tanks, the Marine Park area allows seals and sea lions to swim in the actual ocean. You can purchase buckets of fish to feed these energetic animals yourself while enjoying panoramic views of the Sea of Japan from the rugged cliffs of Shukutsu.What truly sets Otaru Aquarium apart is its refreshingly unpolished charm. Unlike modern high-tech facilities, this aquarium embraces the wild Hokkaido environment. The penguin show is legendary across Japan for its "rebellious" performers; the birds often ignore trainers entirely, wandering off to explore or simply standing still, creating a hilarious spectacle far more authentic than a choreographed routine. During winter, the Penguin Walk provides a much closer encounter than the crowded versions found elsewhere in the region. For a unique sensory experience, visit the touch area to feel the surprisingly rough skin of giant octopuses native to local waters. If you visit in warmer months, look out toward the bay from the coastal area; you might spot wild seals from the nearby sanctuary peeking their heads out of the waves, drawn by the calls of their captive cousins. Before leaving, head to the restaurant for a bowl of shako (mantis shrimp) ramen, a local Otaru delicacy. It is a rugged, windswept, and heartwarming destination that captures the true spirit of Hokkaido's maritime heritage, located just a short bus ride from the historic Otaru Canal area.View on Traveldoko
3HokkaidoAOAO SAPPOROA futuristic urban aquarium where science and art meet in the heart of Sapporo.Located inside the moyuk SAPPORO complex, this facility prioritizes "observation" over mere spectacle. Explore the Laboratory area to see staff preparing food and maintaining tanks, or wander through the Green Aquarium, featuring lush underwater forests designed by world-renowned aquascapers that bridge the gap between nature and architecture.The highlight for many is the penguin zone, featuring a world-first hexagonal tank system. These unique structures allow Northern Rockhopper penguins to hop between floating islands, mimicking their natural behavior in a way standard tanks cannot. Nearby, the "Blue Room" offers a sensory escape, using immersive digital projections of the ocean floor to create a meditative atmosphere. Unlike traditional aquariums, AOAO encourages a slow pace; the "Library Aquarium" section pairs marine life with related books, inviting you to sit and read. For the best experience, visit during the evening hours when the lighting shifts to a moody, sophisticated "night mode." You can grab a croissant or a local craft beer from the onsite Shirokuma Bakery & and wander the exhibits with a drink in hand—a rare luxury in Japanese attractions. Located just steps from the Tanukikoji shopping arcade, it is the perfect sanctuary for a snowy day or a post-shopping wind-down. The facility stays open until 10 PM, making it an ideal spot for an after-dinner date or a quiet late-night stroll among the jellyfish.View on Traveldoko
