Visiting Osaka Castle and Nishinomaru Garden

Osaka castle

One of the most famous historical sites in all of Japan, Osaka castle is situated right in the heart of the city of the same name and distinctive for its unique roof shape and stately white walls with gold leaf accents.

Surrounded by thick rock walls, moats and the stunning Nishinomaru Garden, the castle is particularly popular among tourists during the Sakura cherry blossom in the spring.

How to get to Osaka Castle

Osaka Castle is easily accessible from the JR Osakajokoen Station. Use your Japan Rail Pass to access the station.

For example, you can travel from Namba to Osakajokoen Station on the JR West Osaka Loop Line. Exit the station to the west and cross into the Osaka Castle Park. From there, you can meander lovely trails to reach the castle proper.


Osaka Castle stands on the former site of the Ishiyama Hoganji Temple. In 1583, during the Sengoku period, warrior and feudal lord Toyotomi Hideyoshi desired to build a castle that both mirrored and exceeded that of fellow lord Oda Nobunaga. It would serve as the ruling epicenter of a recently unified Japan. The castle, the largest of its time, was completed in 1597, and Toyotomi died the following year.

In the year 1600, a 200,000-man army came up against the castle. Though outnumbered two to one, the Toyotomi forces routed the army thanks to the castle’s unique defenses. By 1620, however, the Tokugawa clan overtook the castle and its buildings burned. The castle and its walls were then rebuilt. Over the years, conflict, accident, and natural disasters inflicted damage to the castle buildings. Much of it burned during civil conflicts in 1868, and the grounds became an arsenal that manufactured guns and ammunition for the Japanese army.

In 1931, the current castle structure was rebuilt. But, as the castle was a major military armory, it was bombed during World War II. Finally, in 1995, the government of Osaka embarked on a project to restore the castle to its former glory. Work was completed in 1997.

Castle grounds

The castle grounds are approximately 15 acres, or two square kilometers, in size. Thirteen structures have been designated as “cultural assets.” These include:

  • The Ote-mon Gate
  • Three sections of castle walls located around this gate
  • Sakura-mon Gate
  • Ichiban-yagura Turret
  • Inui-yagura Turret
  • Rokuban-yagura Turret
  • Sengan Turret
  • Tamon Turret
  • Kinmeisui Well

  • Enshogura Gunpowder Magazine

The castle is surrounded by moats and steep rock walls. The main tower has five visible stories and eight total stories. The exterior of the building is a reproduction of the original. The interior functions as a museum on the history of Osaka castle and the surrounding city. At night, the castle grounds are illuminated by sodium lamps.
