#5 Tsutenkaku Tower
Standing proudly in Osaka’s retro Shinsekai district, Tsutenkaku Tower is one of the city’s most recognizable landmarks. Originally built in 1912 and rebuilt after World War II, this 103-meter tower is a nostalgic symbol of Osaka’s resilience and charm. Inside, you’ll find observation decks that offer sweeping views of the city, quirky exhibits, and even a golden statue of Billiken — Osaka’s “god of happiness.”
The streets surrounding the tower buzz with local life. Wander through alleys glowing with neon signs, stop for crispy kushikatsu skewers at one of the traditional eateries, or try a retro game in a vintage arcade. The atmosphere here feels like stepping back in time to the Showa era.
Recommended experience: Join a Shinsekai Walking Tour or Osaka Night Lights Experience to explore the area’s history and hidden gems with a local guide.
#4 Osaka Castle Park
Surrounding the city’s most famous landmark, Osaka Castle Park is an enormous green oasis in the heart of the city. Spanning more than 100 hectares, it’s a favorite local spot for jogging, cycling, and cherry blossom viewing in spring. The park’s tranquil atmosphere contrasts beautifully with the city’s modern energy, offering plenty of benches, gardens, and walking paths.
During springtime, over 4,000 cherry trees bloom across the park, transforming it into one of Japan’s most photographed hanami locations. Autumn brings its own beauty, with fiery red maple leaves surrounding the moat and castle walls.
Travel tip: Bring snacks or a picnic and enjoy a relaxing afternoon near Nishinomaru Garden for one of the best castle views. You can also rent a bike to explore the park more comfortably.
Recommended pass: The Osaka Amazing Pass includes entry to Osaka Castle’s museum and offers unlimited subway rides for a day of sightseeing.
#3 Osaka Castle
Few landmarks in Japan are as iconic as Osaka Castle. Originally built in the 16th century by samurai leader Toyotomi Hideyoshi, it played a key role in Japan’s unification. The castle’s impressive stone walls, gold-leaf details, and traditional architecture make it one of Osaka’s most photographed sites.
Inside the castle, visitors can explore a fascinating museum that showcases samurai armor, ancient artifacts, and panoramic displays about Osaka’s feudal history. At the top floor, an open-air observation deck rewards you with a breathtaking 360-degree view of the surrounding park and skyline.
For photographers, sunset is the best time to visit — the castle glows golden against the evening sky. Arrive early if you want to avoid crowds, especially on weekends.
Recommended experience: Book a Skip-the-Line Osaka Castle Tour or Combo Ticket that includes entrance and a guided walking route through the park.
#2 Osaka Aquarium Kaiyukan
Located in the Tempozan Harbor Village, the Osaka Aquarium Kaiyukan is one of the largest and most spectacular aquariums in the world. Its massive tanks recreate diverse marine environments from across the Pacific Ocean, from icy Arctic seas to tropical coral reefs. The main tank, representing the Pacific Ocean, houses a majestic whale shark — the aquarium’s star attraction.
Visitors walk along a circular route that spirals downward, offering different perspectives of the same massive tank. You’ll come face to face with penguins, dolphins, rays, and jellyfish — a mesmerizing experience for both adults and children. The lighting and soundtrack make each zone feel like an immersive underwater journey.
Right outside, the Tempozan Marketplace offers restaurants, souvenir shops, and even a large Ferris wheel with panoramic bay views.

The Umeda Sky Building is a masterpiece of modern architecture and one of Osaka’s most photographed landmarks. Comprising two 40-story towers connected by the Floating Garden Observatory, it offers a breathtaking 360° view of the city. From here, you can see the Yodo River, Osaka Bay, and the endless sea of skyscrapers stretching to the horizon.
Visit in the late afternoon to catch the golden sunset and stay until nightfall when Osaka’s city lights create a dazzling spectacle below. The observatory’s open-air circular deck is especially romantic — a popular spot for couples and photographers alike.
At the base of the building, you’ll find Takimi Koji Alley, a retro-style underground food court that recreates the atmosphere of post-war Japan with nostalgic eateries and lantern-lit corridors.
