Osaka Aquarium Kaiyukan, Public aquarium in Tempozan Harbor Village, Japan
The Osaka Aquarium Kaiyukan is a marine facility in the Tempozan Harbor Village district and houses hundreds of animal species from the Pacific across eight floors. Each section is dedicated to a particular geographic part of the Pacific basin and displays life in different habitats.
The facility opened its doors in the summer of 1990 following a design by architect Peter Chermayeff. It later received recognition for its building construction through an award for public structures.
The circular spiral ramp descends through several levels and lets visitors feel as though they are diving into the sea themselves. This downward walkway brings guests eye to eye with animals from different depths.
The nearest subway station is Osakako on the Chuo Line and sits about five walking minutes from the entrance. Opening hours and admission fees change according to season, so checking ahead before a visit helps.
The middle tank reaches a depth of about 9 meters (roughly 30 feet) and contains a whale shark that re-creates open ocean conditions along with numerous fish. This central water basin stretches vertically through several floors and can be observed from different levels.

Marine museums present the history of seafaring, scientific exploration of the oceans, and the diversity of marine life. These institutions display ship models, nautical instruments, aquariums with living sea creatures, and exhibitions about oceanography. Visitors learn about historical voyages of discovery, modern ocean research, and the protection of marine ecosystems. Notable examples include the Oceanogràfic in Valencia with its various marine biotopes, the National Maritime Museum in Amsterdam with its collection on Dutch naval history, and the Oceanographic Museum of Monaco, founded in 1910. The Maritime Museum of San Diego preserves historic vessels, while the Museum of Oceanography in Sopot documents Baltic Sea research. These museums combine scientific education with the fascination for seas and oceans.
Osaka is Japan of contrasts. A city where 6th-century temples stand beside futuristic skyscrapers, where fish markets meet giant Dotonbori signs, and where the nights turn streets into a continuous show. More lively and spontaneous than Tokyo, Osaka maintains its accent, humor, and warmth. People come here to eat, stroll, and listen to the hum of a metropolis that never truly sleeps. Between medieval castles, Shinto shrines, avant-garde museums, and multi-level hot spring baths, the city presents both ancient and ultra-modern faces. Exploring Namba, Shinsekai, or Umeda reveals a unique energy, vibrant urban culture, and an attention to detail that makes Japan unforgettable.
