Osaka Castle is a historic gem in Japan's lively western capital, offering a peaceful escape from the city hustle. Originally built by Toyotomi Hideyoshi in the late 1500s, the current reconstruction stands as a symbol of Japan's past and a popular spot for cherry blossom parties in spring. You can explore the castle grounds for free, enjoy picnics under blooming trees. Or visit the castle from the inside to get a better insight of the Edo Period.
