Osaka Castle is not only a symbol of Japan’s rich history but also full of hidden gems that many visitors miss. While most people head straight to the castle’s main tower (Tenshukaku) for its panoramic views of Osaka, few know that the original stone walls were discovered underground during excavations.
These ancient stone walls, some dating back to the era of Toyotomi Hideyoshi, can be explored at the Stone Wall Museum, which is conveniently included with your castle tower ticket. Surprisingly, many visitors skip the museum and miss this rare opportunity to see the foundation of one of Japan’s most iconic castles up close.
Visiting both the Tenshukaku and the Stone Wall Museum allows you to fully appreciate Osaka Castle’s historical significance—from the impressive architecture above ground to the hidden history beneath your feet. Don’t miss this chance to uncover the secrets hidden in the castle’s stone walls!
