Trivia & Fun Facts About Osaka Prefecture (1–10)
The Tower of the Sun has a missing fourth face.
The Tower of the Sun, created as an exhibit for Expo ’70—the first world’s fair held in Japan—can be considered a representative monument by Taro Okamoto.
The tower features multiple faces imbued with various meanings, and there was once a fourth face that went missing.
This fourth face, called the “Sun of the Underworld,” was located in the underground exhibition hall and is said to have disappeared during dismantling after the expo closed.
Although the original vanished, a replica was later reconstructed based on photographs and interviews and is now on display.
Since the work includes this fourth face, which is separate from the main tower, it’s recommended to check it out as well when you visit.
The original Tsutenkaku Tower had a design that combined the Arc de Triomphe and the Eiffel Tower.
Tsutenkaku, which stands at the heart of Osaka’s Shinsekai district, is a beloved landmark and symbol of the city.
The current tower is the second generation, completed in 1956, while the original Tsutenkaku had an intriguing design that combined the Arc de Triomphe and the Eiffel Tower.
Built in 1912 along with Shinsekai’s Luna Park, it was cherished as one of Japan’s three great lookout towers.
However, it was severely damaged by fire in 1943 and subsequently dismantled due to the wartime demand for steel.
The design, which incorporated and combined famous overseas landmarks, strongly conveys a sense of extravagance and flamboyance.
The stone walls of Osaka Castle were transported using kelp.
Osaka Castle, built by Toyotomi Hideyoshi between 1583 and 1598.
Although its original appearance can no longer be seen due to the Summer Siege of Osaka, some trivia about its construction remains.
It’s said that when transporting the large stones used for the castle’s stone walls, they took advantage of the slipperiness of kelp.
Wooden sleds were used as equipment to haul stones from various regions of Japan, and large amounts of kelp soaked in water were used to make the sleds slide more smoothly.
The merchants of Osaka thought it wasteful to discard the huge quantities of kelp that had been brought into the city and had served their purpose.
When they simmered the kelp in soy sauce, a delicious broth resulted, and from there, Osaka’s kelp-dashi culture is said to have been born.
Osaka is the birthplace of conveyor-belt sushi.
Conveyor belt sushi restaurants can be found all over Japan, including many chain stores.
Did you know that the birthplace of conveyor belt sushi is Osaka? Specifically, it’s in Higashi-Osaka City.
The sushi restaurant “Mawaru Genroku Sushi No.
1,” which opened in 1958, is credited as the origin, and the chain now operates mainly in the Osaka area.
The owner, who originally ran a standing sushi bar, got the idea for conveyor belt sushi after seeing beer being produced on a conveyor belt.
Later, after exhibiting at the 1970 Osaka Expo, the concept spread nationwide.
The balustrade of Ebisubashi is decorated with a trowel motif.
Dotonbori is famous as a sightseeing spot in Osaka, and among its landmarks, Ebisubashi—known for the iconic Glico sign—is especially crowded.
On this quintessential Osaka bridge, the railings are designed to look like metal spatulas used for okonomiyaki.
It’s a distinctive design, but there are so many of them that you might overlook the detail unless it’s pointed out.
Precisely because this is a place where your attention tends to go straight to the Glico sign, this little bit of trivia encourages you to notice the finer details.
