Osaka is a city bursting with energy, culture, and world-class attractions, but one of its alternative offers is one of the largest and most impressive aquariums in the world! Kaiyukan offers visitors a chance to dive into the wonders of the ocean without leaving the city.
When my husband and I visited Osaka, we made it a point to spend an afternoon at this attraction. It’s a perfect stop for families, couples, or anyone who loves marine life and immersive experiences. Here’s how to make the most of your visit to Kaiyukan and the surrounding area.
Morning: Osaka Aquarium Kaiyukan
From central Osaka, head to Osaka Station and take the Osaka Loop Line to Bentencho Station. Transfer to the Chuo Line, which will take you to Osakako Station near the aquarium. The journey takes about 30 minutes and costs ¥280 (£1.50) one way. Alternatively, taxis are convenient but will cost around ¥2,000 (£11).
As you approach the aquarium, you’ll notice its striking architecture—a massive glass-and-steel structure inspired by the natural world. Tickets cost ¥2,700 (£15) for adults and can be purchased online in advance to avoid queues. Note to purchase them directly from the venue itself. You can turn up on the day if you don’t mind queues.
Start your visit by stepping into the aquarium’s immersive world. Kaiyukan’s unique design takes you on a spiral journey around its central tank, featuring the majestic Pacific Ocean exhibit. Here, you’ll encounter the aquarium’s star resident, a whale shark, peacefully gliding through the water alongside manta rays and shoals of fish.
Each exhibit is themed around a specific region of the Pacific Rim, such as the Aleutian Islands, the Great Barrier Reef, and the Japan Deep Sea. Highlights include playful sea otters, jellyfish, and adorable penguins waddling about. Plan to spend at least two to three hours exploring all 15 tanks.
Lunch: Tempozan Market Place
After your visit, head next door to the Tempozan Market Place. This shopping and dining complex offers a variety of food options, including fresh seafood, ramen, and takoyaki (Osaka’s famous octopus-filled street food). A typical meal will cost around ¥1,000–¥1,500 (£6–£8).
If you’re in the mood for something sweet, try the matcha-flavoured ice cream or a freshly baked melon pan. The market also has plenty of souvenir shops where you can pick up quirky marine-themed gifts.
Afternoon: Tempozan Harbour Village
Once you’ve refuelled, take some time to explore Tempozan Harbour Village, the area surrounding the aquarium. One of the main attractions here is the Tempozan Giant Ferris Wheel, one of the tallest in Japan. For ¥800 (£4.50), you can enjoy views of Osaka Bay, the city skyline, and even as far as Mount Rokko on a clear day.
For those travelling with kids, the nearby LEGOLAND Discovery Centre is a fun indoor attraction. Alternatively, you can simply take a relaxing walk along the harbour and watch the boats pass by.
Evening: Sunset Cruise or Return to Central Osaka
If you have time before heading back to central Osaka, consider taking a Santa Maria cruise, which departs from the harbour and offers dinner and sunset tours of Osaka Bay. Tickets cost ¥1,600 (£9), and the experience provides a serene way to wind down your day.
I hope this guide helps you plan your trip and inspires you to include Kaiyukan on your Osaka itinerary.
