Osaka is a city in the Kansai region of Japan’s main island of Honshu.
Osaka, the working heart of Kansai, is a good place to experience a modern Japanese city.
What I found here? Osaka-jo. (Osaka castle). The castle was built as a display of power by Toyotomi Hideyoshi after he achieved his goal of unifying Japan. One hundred thousand workers toiled for three years to construct an ‘impregnable’ granite site.
