Osaka Castle and Museum

Learn about the turbulent history of Osaka Castle by stepping inside the iconic building and exploring its museum. There are eight floors, each with exhibits that tell the castle’s fascinating story. You’ll also notice a lot of gold decorations inside and outside the building, a nod to Toyotomi Hideyoshi, the gold-obsessed feudal lord who built the first castle on this site over 400 years ago. Head up to the top-floor observation deck for stunning views of Osaka across the park.
