Osaka Castle is a well-known masterpiece of Japanese castle architecture. Within the castle, the essence of defense design from the Sengoku period to the Edo period can be seen throughout. The Tenshukakari-mon gate is an example of this, serving as a place that tells the story of the castle's strong defense.
The Tenshukakari-mon gate is located at one corner of the path leading to the central area. This gate faces east and was designed to anticipate invasion from the north. The purpose of the staggered stone walls on both sides was to obstruct the enemy's direct advance.
If the enemy were to attack from the north, they would be led into a meandering passage. This structure confined the enemy's movements and made it easier to counterattack from a favorable position.
The clever construction of this gate was re-evaluated by the Edo shogunate. The engineers of that time noticed the defensive ingenuity and highly praised the significance of the Tenshukakari-mon gate. However, the gate itself was lost in a great fire during the Meiji Restoration period. Only the remains of the gate exist at the site today.
Standing at the remains of the Tenshukakari-mon gate, one can reminisce about the magnificence of the castle. It feels as if the determination to defend is engraved in every piece of the sturdy stone walls.
When visiting Osaka Castle, be sure to make a stop at the remains of the Tenshukakari-mon gate. It's also interesting to imagine the scenery of the castle town while pondering on the history. You will truly be able to savor the charm of Osaka Castle.
