Shinsekai is the place to experience the Osaka of old, and Tsutenkaku Tower is the defining landmark of the area. The 100-meter steel tower may not appear particularly tall by modern-day standards, but it has carved out its own place in local history as a symbol of progress and innovation. Head to the top to get a pleasant view of the city, where you can also see exhibits and artifacts showing the vibrant history of the area.
From Osaka/Umeda Station, take the Midosuji Subway line to Dobutsuen-Mae Station. Upon exiting the station, look up for the 100-meter tall steel structure, and head towards it. The walk will take you a little under 10 minutes.
The first incarnation of the tower went up in 1912, connecting to an adjacent amusement park via cable car. At the time, its 64-meter height made it the tallest in all of Asia. After the war, the city rebuilt the tower to a 100-meter height, installing bright neon lights that change color with the seasons.
Tsutenkaku and Shinsekai together make a must-visit destination and can fill two to three hours of your schedule. Consider making a full day of it by visiting the adjacent Tennoji neighborhood, home to the tallest building in Japan.
