The Expo worth visiting
happened in 1970.
Yes — while the 2025 Expo site sits empty, the 1970 one is still paying out. Tarō Okamoto's Tower of the Sun — 70 metres, three faces for past, present and future — is the defining icon of postwar Japanese design, and the park around it costs under ¥500 to enter (posted prices conflict; verify at the gate). The catch everyone misses: the tower's interior, with its Tree of Life climbing the hollow core, requires advance online booking and sells out weeks ahead. Add the genuinely world-class National Museum of Ethnology, and NIFREL at EXPOCITY for kids. Reaching it is a ~30–40 minute, ¥500–700 Midōsuji-plus-monorail ride — and closed Wednesdays will burn you outside the spring and autumn seasons.
Is it for you?
Who it suitsOkamoto's tower, and the museum nobody tells you about
What you're going forThe 1970 Expo drew 64 million people. What it left behind is better than what most Expos leave: one great monument, one great museum, one great lawn.
The Tower of the Sun (太陽の塔) is 70 metres of concrete defiance by artist Tarō Okamoto — three faces (the golden future face at the crown, the present face on the front, the black sun of the past on the back) rising through what was once the Expo's central pavilion roof. It has become the defining icon of postwar Japanese design. The outside is free with park admission; the interior — reopened after decades, with Okamoto's Tree of Life sculpture spiralling up the hollow core — is a separate timed ticket that must be booked online in advance and sells out weeks ahead. If the inside matters to you, book it before your flights are even comfortable.
The park's second act is the National Museum of Ethnology (Minpaku) — one of the world's great anthropology collections, vast, superbly displayed and almost untouristed. Give it two hours minimum. Around the park's edge at EXPOCITY: NIFREL, the Kaiyukan team's aquarium-zoo-art hybrid where most exhibits are at touching height (the best under-8s attraction on this side of the city), plus the Redhorse Osaka Wheel, Japan's tallest at 123 m. The lawns and gardens between them are the picnic Osaka's dense centre never offers — roughly 3,000 cherry trees in late March, and one of Kansai's best foliage shows around late November. Osaka summers are now genuinely dangerous: 2025 was the hottest since records began in 1898, afternoons run 36–38°C at 70% humidity, and nights stay above 25°C. From late July to mid-September, plan indoor afternoons and treat 10:00–17:00 as heat-illness territory, not sightseeing time.
Two logistics traps: the park is closed Wednesdays except during the April–early-May and October–November peak seasons, and posted admission has been listed variously at ¥260–450 — treat it as "under ¥500, verify at the gate." Getting there is half the fun if you like infrastructure: Midōsuji line north to Senri-Chūō, then the Osaka Monorail one ride to Banpaku-kinen-kōen — about 30–40 minutes and ¥500–700 from central Osaka, with the tower's golden face visible from the monorail window on approach.

Expo '70 Park questions people actually search
FAQPage schema pairedCan you go inside the Tower of the Sun?
Yes — but only with an advance online reservation, and slots sell out weeks ahead. The interior holds Tarō Okamoto's Tree of Life, a sculpture climbing the tower's hollow core. There are no walk-up tickets; book as soon as your Osaka dates are fixed.
How much does Expo '70 Park cost?
Under ¥500 for park entry — posted prices have appeared as anything from ¥260 to ¥450, so verify at the gate. The Tower of the Sun interior, the National Museum of Ethnology and NIFREL are all ticketed separately on top.
How do I get to Expo '70 Park from Osaka?
Midōsuji line north to Senri-Chūō (from Namba or Umeda, one train), then the Osaka Monorail one ride to Banpaku-kinen-kōen — the park gate is about 5 minutes from the station. Around 30–40 minutes and ¥500–700 each way.
Is Expo '70 Park open on Wednesdays?
Usually not — the park closes on Wednesdays, except during the April–early-May and October–November peak seasons when it opens daily. Check the calendar before committing the day; it's the most common way this trip gets burned.
What is NIFREL?
An aquarium-zoo-art hybrid at EXPOCITY, made by the team behind Kaiyukan, with most exhibits at touching height — white tigers, miniature hippos, free-flying birds. It's the best attraction for under-8s on the north side of Osaka, and it's outside the park gate so it works even on park-closed Wednesdays.
Is the Tower of the Sun from the 2025 Expo?
No — it's the icon of the 1970 World Expo, which drew 64 million people to the same city 55 years earlier. The 2025 Expo on Yumeshima closed in October 2025 and its site has nothing to visit; the 1970 site is the one that became a permanent park.
