This is the Osaka Castle.
It’s history is fascinating – this wasn’t the original structure built! It was once meant to be the centre of a unified Japan during Hideyoshi’s time. However, the castle was destroyed following his death, and the rebuilt version was then struck by lightning. What we see here was built in 1931 and had somehow survived the war.
I’d spent half a day around the castle grounds. The castle was a museum that detailed the history of the castle, battles, and Hideyoshi’s life. It was interesting, but I was more keen to look at the stone walls and moats surrounding the castle tower. Take a walk around the castle grounds and gardens!
PS: If you’re planning a visit, it’s easily accessible by the JR Osakajokoen Station. Step off the train, out the station, and keep walking around what seems like an entire imperial city! It’s beautiful!
