Naniwa Nagara-Toyosaki Palace (難波長柄豊崎宮 Naniwa Nagara-Toyosaki-no-miya?), or Naniwa Palace (難波宮 Naniwa-no-miya?) in short, is a historical Japanese palace which was located in present-day central Osaka city. The Palace of this period is also sometimes referred to as the Former Naniwa Palace, as opposed to the Latter Naniwa Palace in 744.
Ruins of the ancient palace were found by a local archaeologist Tokutaro Yamane in 1957, although no obvious trace is found to date that there was a city formed around or close to the palace. When the ruins came out, Yamane left a saying Ware maboroshi no daigokuden o mitari!, "I saw the shade [i.e., ghostly or illusory] daigokuden [main palace building]!"
