Unusual things to do in Osaka go far beyond Dotonbori takoyaki and Osaka Castle – the city has built a global reputation for the quirky, the weird, and the genuinely surprising. A skyscraper has a highway running through floors 5-7; a luxury bar requires no ID but unofficially welcomes Star Wars fans; the city’s premier garbage incinerator was designed by Friedensreich Hundertwasser as public art; Tsutenkaku Tower has a 60-meter indoor slide; and you can build your own Cup Noodles flavor at the Ikeda museum. This 2026 guide profiles 18 unusual Osaka experiences, organized by category, with practical visit information for each.
Architectural Oddities
1. Gate Tower Building (Fukushima Ward)
The Hanshin Expressway literally passes through floors 5-7 of this 16-story office building. The highway is structurally independent of the building – a “tube” cuts through the structure with no physical contact. Office tenants share an address with a highway. Free to view from outside (photograph from across the street). Access: Fukushima Station (JR Osaka Loop Line).
2. Maishima Sludge Center (Hundertwasser Garbage Plant)
Friedensreich Hundertwasser – the Austrian architect/artist who designed Kids Plaza Osaka’s climbing castle – was commissioned to design Osaka’s waste incinerator. The result is a building that looks like a Disney mushroom – golden onion domes, undulating walls, primary-color tiles, a chimney covered in mosaic. Public tours by reservation; free. Access: Maishima Sports Island bus from Sakurashima Station.
3. Isshinji Temple Concrete Modernism (Tennoji)
The 1997 concrete-modernist Buddhist temple housing Bone Buddha statues. One of Japan’s most architecturally striking modern temples. Free admission. See our Isshinji Temple guide.
Quirky Museums
4. Cup Noodles Museum Ikeda
The birthplace of instant ramen. Trace the history of Momofuku Ando’s 1958 invention. The highlight: design your own cup noodles flavor (JPY 500 per cup) – choose soup base, 4 toppings from 12 options, and decorate the cup. Hands-down one of the best unusual Osaka experiences. Free entry (cup-making is paid). Access: Ikeda Station (Hankyu Takarazuka Line), 5-min walk.
5. Sewerage Science Museum
Six floors dedicated to Osaka’s sewer system. Walk through giant toilet-seat displays, learn about wastewater treatment, see historical sewage equipment. Free. Free for kids who find this universally hilarious. Access: 10 min walk from Maishima or Sakurashima Station.
6. Mizuno Printing Museum (Yodogawa Ward)
One of Japan’s largest printing-history museums. 5 floors of antique presses, woodblocks, type, and printing techniques. Free admission. For design and history buffs.
7. Takoyaki Museum (Universal CityWalk)
Adjacent to USJ. DIY takoyaki cooking + 5 vendor stalls competing for “best takoyaki” title. Pay-as-you-eat (typically JPY 1,500-3,000 for a sampling tour). Access: Universal City Station.
8. Osaka Museum of Housing and Living
A full-scale recreation of Edo-period Osaka neighborhood with day-night lighting cycle every 15 minutes. Walk through 1830s streets with sound effects, working storefronts, and weather changes. Adult JPY 600. Access: Tenjinbashisuji 6-chome Station.
Themed Cafes and Bars
9. Cat Cafe Calico (Shinsaibashi)
Drink with cats. Cover JPY 1,200/hour includes one drink. The most popular themed cafe in Osaka. Several other cat cafes in Namba and Umeda offer variations.
10. Owl Cafe (Multiple Locations)
Drinks with live owls. JPY 1,500/hour. Photogenic but ethically debated – several owl welfare organizations criticize the practice; check current animal-welfare conditions before visiting.
11. Unlicensed Star Wars Bar (Nakanoshima)
An unlicensed but tolerated Star Wars-themed bar with Stormtrooper decor, themed drinks, and lightsabers. Cover JPY 1,500 includes one drink. The owner has carefully kept the bar small enough to avoid Disney enforcement. Find via Atlas Obscura.
12. Cafe & Bar Skylounge (Conrad Osaka)
Not technically themed but visually unusual – the 40th-floor cocktail bar with views over the Nakanoshima river. The “Anti-Gravity Cocktail” (JPY 2,500) is presented in a curious upside-down glass.
Thrill and Active Experiences
13. Tsutenkaku Tower 60-Meter Indoor Slide
The “TOWER SLIDER” was installed in 2022. A 60-meter spiral slide takes you from the 3rd-floor observation deck to the basement in 10 seconds. JPY 1,000 per ride. Adult-only (size restrictions). Tower admission JPY 1,000 separate. Combine with the rest of Shinsekai for a half-day.
14. Mario-Style Go-Kart Tours
Costume rentals + go-karts driven on public Osaka streets. JPY 8,000-12,000 per person. Requires international driving permit. Routes pass major landmarks (Dotonbori, Osaka Castle). Disputed by some city officials but operating legally with proper permits.
15. Spa World 7-Continent Onsen
Massive onsen complex in Shin-Imamiya with European-themed baths (Roman columns, Greek statues) and Asian-themed baths (Bali, Indonesia, Persia) rotating monthly between genders. Open 24 hours. JPY 1,500-3,000.
Retro and Hidden Spots
16. Naniwa Kuishinbo Yokocho (Tempozan)
1965 Osaka-themed retro food alley inside Tempozan Marketplace. 20+ vendors selling takoyaki, okonomiyaki, ramen, kushikatsu in a recreated Showa-era streetscape. JPY 800-1,500 per meal. Open until 21:00.
17. Hozenji Yokocho Lantern Alley (Dotonbori)
60-meter stone-paved alley with 15 small restaurants and bars. The setting of Sakunosuke Oda’s 1940 novel “Meoto Zenzai.” Atmospheric and photogenic at night. Free to walk; meals JPY 1,500-8,000. See our Hozenji Temple guide.

Final Word: Unusual Things to Do in Osaka
Unusual things to do in Osaka deliver some of the most memorable travel experiences in Japan. Combine 2-3 quirky stops with your standard sightseeing for a balanced trip – the Cup Noodles Museum and Tsutenkaku slide are universally entertaining; the Hundertwasser garbage plant is genuinely striking; Hozenji Yokocho is atmospheric in any weather. Skip the tourist-trap themed restaurants and lean into the city’s authentic weirdness – Osaka is one of the few major cities where quirky cultural offerings remain genuinely affordable and accessible. If this list appeals, the guide to Osaka off the beaten path goes further still.
