How long does it take to walk through Expo '70 Commemorative Park?

Expect to spend at least 2 to 3 hours in Expo Park alone if you plan to visit the museums and gardens. The park covers over 260 hectares, so a self-guided walk allows you to prioritize the stops that interest you most.

Is the Tower of the Sun worth seeing?

Absolutely; it is one of Japan's most significant works of 20th-century public art. While you can admire the exterior for free with park admission, the interior is also open to visitors who book in advance.

Is this walking route family-friendly?

Yes, this route is very family-friendly, featuring wide-open parks, a zoo, and the interactive Solaniwa Onsen. The transition between Suita and central Osaka requires train travel, which helps break up the walking for children.

Can I see Osaka Castle for free?

You can explore the vast Osaka Castle Park, view the massive gates (like Ōte-mon), and see the exterior of the Main Keep for free. However, entering the Main Keep museum and Nishinomaru Garden requires a small admission fee.

What is the best time to visit Nakanoshima Rose Garden?

The best times to see the roses in full bloom are typically mid-May to early June and again in October. However, the park is a beautiful riverside stroll throughout the year.

How do I get from Expo Park to Osaka Castle?

The most efficient way is taking the Osaka Monorail from Banpaku-kinen-koen to Senri-Chuo, then transferring to the Midosuji Line to Umeda, and finally taking the JR Loop Line to Osaka-jo Koen Station.

Is Solaniwa Onsen a traditional hot spring?

It is a modern 'super sento' or theme park onsen. While it uses real natural hot spring water, it focuses on a themed experience with restaurants, games, and relaxation areas styled after the 16th century.

Tour Stops & Points of Interest (15)

National Museum of Ethnology

Welcome to 'Minpaku,' one of the world's largest research museums dedicated to ethnology. Established in the mid-1970s on the former Expo grounds, this facility houses a staggering collection of artifacts representing cultures from every corner of the globe. As you walk through the exhibits, notice the focus on 'interconnectedness'—a core philosophy of the 1970 World Expo. The museum's architecture itself is a marvel of late-modernism, designed by Kisho Kurokawa, a leading figure in the Metabolism movement. It serves as a bridge between the futuristic ideals of the Expo and the timeless traditions of humanity.

Tower of the Sun

Standing nearly 70 meters tall, the Tower of the Sun is the unmistakable symbol of Expo '70. Created by artist Taro Okamoto, the tower features three faces: the 'Face of the Golden Sun' at the top representing the future, the 'Face of the Sun' on the front for the present, and the 'Black Sun' on the back for the past. It was originally part of a massive 'Big Roof' structure. While the roof is gone, the tower remains an avant-garde icon, representing the raw, chaotic energy of life. Its presence here continues to inspire a sense of wonder and artistic rebellion.

Japanese Garden

This 26-hectare garden was created for the Expo to showcase the peak of Japanese landscaping. It is unique because it is divided into four sections, each representing a different era: the Heian, Kamakura/Muromachi, Edo, and Modern periods. As you wander the paths, you are essentially walking through the history of Japanese aesthetic philosophy. From the elegant ponds of the aristocracy to the minimalist Zen rock gardens, this space offers a peaceful retreat that highlights the deep connection between Japanese culture and the natural world.

Expo '70 Pavilion

Housed in the former Steel Pavilion, this museum is a time capsule of the 1970 World Fair. During the Expo, this building featured an 'Space Theater' with a massive array of speakers for cutting-edge acoustic performances. Today, it preserves the memories of the 64 million people who visited the site. Look for the original models, posters, and the famous 'Time Capsule Expo '70' which was buried nearby, intended to be opened 5,000 years in the future. It’s a poignant reminder of an era that looked toward the future with unparalleled optimism.

Dream Pond

The Dream Pond was once the centerpiece of the Expo’s amusement area. Its most famous features were the futuristic fountains designed by Isamu Noguchi. Though the mechanical fountains are now static sculptures, the pond remains a vital part of the park's landscape. Noguchi’s work here blended sculpture with water and engineering, embodying the 'Progress and Harmony' theme. It’s a perfect spot to reflect on how the Expo grounds transitioned from a high-tech playground into a lush, mature forest park over the last five decades.

Izumino Hiroba

Now located in the bustling Umeda district, Izumino Hiroba (Fountain of Information Plaza) serves as a modern urban gateway. While the original Expo-era fountain was recently replaced during renovations, the plaza remains a vital meeting point for art and transit. It represents Osaka’s 'underground city' culture. The current design features a 'Water Tree' light installation that mimics the flow of a fountain, continuing the legacy of water as a central motif in Osaka's urban planning. It marks your transition from the parklands of Suita into the heart of the metropolis.

Nakanoshima Park

Nakanoshima Park is Osaka’s oldest public park, established in 1891 on a narrow island between the Dojima and Tosabori Rivers. This area was the commercial and administrative heart of the city during the Meiji period. As you walk, you'll see grand Western-style buildings like the Osaka City Central Public Hall. The park represents a shift in Japanese urbanism, where public leisure spaces were modeled after European cities. It’s a beautiful example of how Osaka embraced international influences while maintaining its unique riverside identity.

Nakanoshima Rose Garden

Located within Nakanoshima Park, this garden features over 3,000 rose bushes of approximately 310 varieties. When in bloom, the scent is intoxicating and the colors are vibrant against the backdrop of the city's skyscrapers. The rose garden is a favorite for local photographers and couples. It symbolizes the 'Nature' component of our walk, showing how even in a densely packed city like Osaka, floral beauty is meticulously curated and celebrated as part of the public experience.

Nishinomaru Garden

As you enter the Osaka Castle grounds, you find yourself in the Nishinomaru Garden. This lush lawn was once the site of the residence for Kita-no-Mandokoro, the wife of Toyotomi Hideyoshi. It offers the most famous view of the castle tower, framed by hundreds of cherry trees. The garden highlights the defensive yet aesthetic nature of Japanese castle architecture, where wide open spaces served as both a buffer against invaders and a place of high-status beauty for the ruling elite.

Ōte-mon Gate

The Ōte-mon is the main gate of Osaka Castle and a registered Important Cultural Property. Notice the massive 'octopus stone' nearby—a giant granite slab that demonstrates the incredible engineering and power of the Shogunate. The gate’s heavy timber and iron plating were designed to be impenetrable. Walking through this gate, you are following the path of samurai and lords who once entered this fortress. The sheer scale of the masonry here is a testament to the labor and artistry involved in feudal Japanese construction.

Osaka Castle Main Keep

The current Main Keep is a 1931 concrete reconstruction of the original 16th-century tower, but it sits on the original massive stone foundations. Inside, a museum details the life of Toyotomi Hideyoshi, the unifier of Japan who first built the castle. The gold-leaf accents and dolphin-shaped 'shachihoko' on the roof are symbols of prestige and protection against fire. From the top observatory, you can see the entire city, realizing the strategic importance of this site in controlling the surrounding plains and waterways.

Osaka Castle Plaza

This central plaza, surrounding the Miraiza building (a former military headquarters), is the social heart of the castle grounds. Here, history meets modern tourism. The Miraiza itself is an architectural curiosity—a 1930s European-style brick building sitting right next to a traditional Japanese keep. It serves as a reminder of the early 20th-century trend of blending 'Eastern spirit with Western technology.' Take a moment to appreciate the contrast between the medieval walls and the modern skyline visible in the distance.

Naniwa-no-Miya-Ato Park

Long before Osaka Castle was built, this site was the Naniwa Palace, the capital of Japan in the 7th and 8th centuries. Today, only the stone foundations and post holes remain, but the park preserves the footprint of the Daigokuden (Great Hall of State). This is where the Emperor once sat. Standing here, you are at the literal foundation of Japanese statehood. The open space provides a stark, minimalist contrast to the verticality of the nearby castle, reminding us of the city's ancient roots.

Tennoji Zoo

Opened in 1915, Tennoji Zoo is the third oldest zoo in Japan. It was established during a period of rapid modernization when Japan was eager to showcase exotic animals to the public. While it has evolved toward modern conservation practices, it remains a nostalgic landmark in the Tennoji district. The zoo's location, adjacent to the historic Shitennoji Temple and the modern Abeno Harukas skyscraper, perfectly encapsulates Osaka’s ability to stack different eras of history within a single neighborhood view.

Solaniwa Onsen

Your final stop is Solaniwa Onsen, one of the largest hot spring theme parks in Kansai. Designed to resemble the Azuchi-Momoyama period—the era of Hideyoshi—it blends traditional relaxation with modern entertainment. You can walk through a rooftop Japanese garden in a yukata (light kimono), reflecting on the day's journey from the futuristic Expo Park to the ancient palace ruins. It is a fitting end to a walk centered on art and nature, offering a sensory immersion into Japan's golden age of culture.
