About Osaka Castle
Osaka Castle is in Chūō-ku, in the city of Osaka, Japan. It is described as one of the country's most famous landmarks. It had a major part in Japan's unification during the sixteenth century, in the Azuchi–Momoyama period. The keep rises five stories on the outside, with eight inside, and sits on a tall stone foundation. It has two moats, an inner one and an outer one.
Toyotomi Hideyoshi began building the castle in 1583, on the site of the Ishiyama Hongan-ji temple of the Ikkō-ikki. His plan used Oda Nobunaga's headquarters, Azuchi Castle, as its model. The inner donjon was completed in 1585 and the whole project in 1597. Hideyoshi died the following year, and the castle went to his son Toyotomi Hideyori. After the Siege of Osaka in 1614 and 1615, the castle fell to the Tokugawa shogunate, the Toyotomi clan perished, and its buildings burned to the ground.
In 1620 the old structures were dismantled and the shogunate rebuilt the castle. The new walls were made of interlocked granite boulders without mortar, and many of the stones came from quarries by the Seto Inland Sea and carry the inscribed crests of the families who contributed them. Construction of the new tenshu started in 1628 and finished two years later. Lightning burned it down in 1665, and a ferroconcrete tenshu was built in 1931. A restoration completed in 1997 left the keep as a concrete reproduction of the original, including elevators, with an interior intended as a modern museum.

- Stone base and moat edges
- The keep rises from a stepped stone base with fine block lines, beside the moat water. A larger print keeps those lines easier to read.
- One piece with the ground
- Osaka Castle is joined to the ground in the exported file, and the four-side check found no floating parts, so nothing needs gluing.
