The castle is open to the public year-round, offering a unique experience across different seasons.
Please note that the castle may have extended hours during certain festivals and holidays, and it may be closed on specific days for maintenance or special events.
In addition to its regular opening hours, Osaka Castle frequently hosts a variety of special events and cultural ceremonies that may influence visiting hours.
For instance, during the cherry blossom season in early April, the castle grounds may extend opening hours to accommodate evening sakura viewings, a tradition known as "yozakura," where the blossoms are illuminated at night, creating a magical atmosphere.
The castle and its surroundings are also a popular venue for traditional Japanese festivals, including the summer fireworks display and the autumn leaf viewing season, which may also feature extended hours or special programming.
