Yes, there are several locker facilities available for visitors at Osaka Castle, though they tend to fill up quickly during peak tourist seasons or during the cherry blossom period. You can find coin-operated lockers at the major entry points near the castle park, specifically at the JR Osaka-jo Koen Station and the Morinomiya Station. Additionally, there are lockers located near the main gate (Otemon Gate) and close to the Osaka-jo Hall. If the on-site lockers are full, many visitors utilize the larger locker banks at major transit hubs like Kyobashi or Osaka Business Park stations. Within the actual castle museum (the Main Tower), large luggage is typically not allowed for safety and space reasons, so utilizing the lockers in the park or at the station is highly recommended. The lockers usually come in small, medium, and large sizes, with prices ranging from 300 to 700 yen. For very large suitcases that won't fit in standard lockers, some "Luggage Storage" services or tourist information centers in the surrounding area may offer manual storage for a slightly higher fee.
