Sumida Aquarium

Overview

Nestled within the bustling Tokyo Skytree Town, the Sumida Aquarium offers an enchanting escape into the aquatic world, conveniently located on the 5th and 6th floors of Tokyo Solamachi. Opened in May 2012, simultaneously with the iconic Tokyo Skytree, this modern, urban aquarium provides an intimate and immersive experience for visitors of all ages. It is home to a diverse collection of approximately 7,000 to 10,000 marine creatures, representing around 260 to 450 species. Designed to feel like a tranquil park, the aquarium emphasizes close-up viewing, allowing guests to forge a personal connection with the aquatic life.

History & Cultural Background

The Sumida Aquarium's establishment was a significant component of the broader Tokyo Skytree Town urban redevelopment project, spearheaded by Tobu Railway Co., Ltd., to revitalize the Narihirabashi and Oshiage areas of Sumida Ward. Conceptualized and managed by ORIX Real Estate Corporation, the aquarium's design thoughtfully integrates with the historical ties of the Sumida River to water and fisheries, while also championing environmental education. A pioneering aspect of its operation is the complete reliance on a proprietary artificial seawater production system. This innovative approach, developed in collaboration with Nagaoka University of Technology and Taisei Corporation, not only minimizes the carbon emissions typically associated with transporting natural seawater but also ensures a consistently stable and healthy environment for its inhabitants year-round. It was notably one of Japan's first inland aquariums to fully adopt such a system.

What Makes It Special

The Sumida Aquarium distinguishes itself through several unique exhibits and innovative features. Its centerpiece is Japan's largest indoor open tank, a massive 350,000-liter pool that serves as a vibrant habitat for numerous Magellanic penguins and South American fur seals. This open design allows for observation from multiple angles, offering an unobstructed view of their playful antics. The jellyfish zone is another major highlight, captivating visitors with ethereal displays including the 'Big Schale' or 'Big Petri Dish,' a large, flat tank showcasing approximately 500 moon jellyfish, many of which were born and bred within the aquarium itself. A Kaleidoscope Tunnel further enhances this dreamlike experience. The 'Edorium' provides a culturally rich experience, an Edo-themed exhibit dedicated to the art of goldfish keeping. It features nearly 1,000 goldfish across more than 20 varieties, displayed in beautifully crafted tanks that evoke traditional Japanese aesthetics. Additionally, the 'Ogasawara Sea Tank' vividly replicates the diverse marine ecosystem of the Ogasawara Islands, a UNESCO World Natural Heritage site located approximately 1,000 kilometers south of Tokyo. This exhibit features species, including sand tiger sharks, specifically transported from these remote, pristine waters. The aquarium also proudly displays impressive natural aquascape tanks, designed by the renowned Aqua Design Amano (ADA), some of which were considered the world's largest of their kind at the time of their creation, featuring lush aquatic plants and freshwater fish that emulate terrestrial grasslands.

Stories, Fun Facts & Local Details

The Sumida Aquarium is filled with fascinating details and a touch of local charm. Upon its opening, a specific tank housed 634 spotted garden eels, a deliberate and playful nod to the Tokyo Skytree's towering height of 634 meters. A visitor favorite is the unique 'Penguin Relationship Chart,' which meticulously details the names and individual personalities of the aquarium's Magellanic penguin colony. QR codes are available for guests to access English versions, fostering a deeper, more personal connection with these beloved residents. Beyond exhibition, the aquarium is actively involved in conservation efforts, collaborating with Ogasawara Village on projects like nurturing baby green sea turtles before their release into the wild. For a unique treat, the on-site Penguin Cafe offers themed snacks and beverages, including salty vanilla ice cream made with salt sourced from the Ogasawara Islands and even glowing cocktails, adding an extra layer of fun to the visit. The aquarium also emphasizes educational engagement through 'Aqua Base' exhibits and 'Aqua Lab' where visitors can observe the behind-the-scenes work of animal care and jellyfish breeding, highlighting the dedication to marine life.
