Top things to do in Osaka
1. Osaka Castle
Osaka's best known sight, with a pretty castle park around it. The keep is a reconstruction, and the interior is a generic late 20th century building with display cases of artifacts related to the original structure, so treat the exterior and the grounds as the main event.
Combine it with the nearby Osaka Museum of History if you want the background to what you are looking at.
2. Osaka Museum of History
The place to head for the history of Osaka itself, and the natural companion to Osaka Castle nearby.
Pair the two in one outing: castle and park first, museum after.
3. Sumiyoshi Taisha Grand Shrine
One of Japan's oldest Shinto shrines, south of the city center, with a very unusual architecture and a bridge arching over a pond.
Give the shrine gardens time on their own; the maritime view from them inspired the landscape representations known as Sumiyoshi drawings.
4. Shitennō-ji
Near Tennōji station and regarded as maybe the first Buddhist temple in Japan, dating back to the 6th century. The buildings you see today are a reconstruction.
It sits by Tennōji station, so it works well as the first stop of a day in the south of the city.
5. Tsūtenkaku
The landmark tower in the Shinsekai area, with an observation platform at 91 meters.
Build the stop around Shinsekai rather than the tower alone, and go up for the view over the district.
6. Osaka Aquarium Kaiyukan
One of the world's largest aquariums, with plenty of sharks including a whale shark, plus dolphins, otters and seals.
Nearby are the Tenpozan Ferris Wheel, the Suntory Museum, a mall, and the ferry to Universal Studios across the water, so you can fill a half day without moving far.
7. Umeda Sky Building
A weirdly shaped building with an observation deck and an escalator suspended between two buildings mid-air, near Osaka station.
Its position by Osaka station makes it an easy add-on to a Kita-side evening rather than a trip of its own.
8. Universal Studios Japan
Japan's second-largest theme park, in the Osaka/Bay Area.
It shares the bay area with the aquarium and the Tenpozan Ferris Wheel, so pick one for the day rather than trying to squeeze in both.
9. National Bunraku Theater
Near Osaka Castle, one of the last places in the world where bunraku, the Edo-period puppet theater, can be seen live. The large puppets require three operators each and are accompanied by traditional music and narration.
Because it is close to the castle, it pairs naturally with a castle visit earlier the same day.
10. Japan Mint
In Osaka, and especially famous for the nearby cherry blossom tunnel road, a prime spot for the annual cherry blossom.
Time this one to the blossom season; the tunnel road is the reason to come.
11. Hirano Old City
A well-saved historical city in Hirano that was originally independent from Osaka, with many temples and shrines.
Touring the Ecomuseum of Hirano, called Hirano Machigurumi Museum, is a good way to feel the city history and the ninjo of Hirano Old City.
12. Osaka Science Museum
An interactive activity center on Nakanoshima with a planetarium and cinema.
Nakanoshima also holds the festival hall, so you can combine a museum visit with an evening recital nearby.
13. Open Air Museum of Old Farmhouses
In Ryokuchi Park, a collection of Edo period farmhouses that gives a good insight into the lives of common people during that period. It is north of the city center.
Allow time for the park around it, since the museum is set within Ryokuchi Park.
14. Kamigata Ukiyoe Museum
In Namba, dedicated to ukiyoe, the Japanese woodblock prints.
Namba is also the setting for the Naniwa and Namba district names that survive from the city's older identity, so it slots into a central Osaka day.
15. Spa World
In Tennoji, with gender-separated European and Asian-themed spas and saunas, plus a pool for the family with slides. There are also outdoor onsen, a bar, a gym, massages and body scrubs.
Put it at the end of a Tennoji day, after Shitennō-ji.
If you only have one day
Morning: Start at Osaka Castle and its park, then walk to the nearby Osaka Museum of History for the background to the city.
Afternoon: Head south to Shitennō-ji near Tennōji station, then continue to Tsūtenkaku in Shinsekai for the observation platform and the district around it.
Evening: Finish at Spa World in Tennoji, or, if you would rather end with a performance, check what is on at the National Bunraku Theater near Osaka Castle and arrange the day around that instead.
Frequently asked questions
Is Osaka Castle worth visiting if it is a reconstruction?
Yes, with the right expectations. The reconstruction is basically only skin deep and the interior is a generic late 20th century building with some display cases, but the castle is pretty and has a nice castle park. For the fuller picture, add the nearby Osaka Museum of History.
Where can I see bunraku performed?
The National Bunraku Theater, near Osaka Castle, is one of the last places in the world where bunraku can be seen live. The large puppets require three operators each and are accompanied by traditional music and narration.
What is there to do around Osaka Aquarium Kaiyukan?
Nearby are the Tenpozan Ferris Wheel, the Suntory Museum, a mall, and the ferry to Universal Studios across the water, so the aquarium can anchor a full half day in the bay area.
When is the best time to see cherry blossoms in Osaka?
The Japan Mint is especially famous for the nearby cherry blossom tunnel road, a prime spot to see the annual cherry blossom.
Decide which of these anchors your trip, then build the rest of your days around it.
