Tayasu Gate

Tayasu Gate is a historical entrance on the north side of the Imperial Palace with two perpendicular passages that form a masugata structure. This double-angled layout forced anyone entering to change direction multiple times before reaching the inner grounds.

The gate was built in 1636 as part of Edo Castle's defenses during the Tokugawa shogunate when this fortress was one of the world's largest. It was later incorporated into the new Imperial Palace complex after the Meiji Restoration and designated as an Important Cultural Property in 1961.

The name comes from a feudal family that once held land nearby, and the gate's squared design reflects how samurai fortifications controlled who could enter and exit the palace grounds.

The gate is about a five-minute walk from Exit 2 of Kudanshita Station along a quiet path with clear signs. Access can sometimes be restricted during imperial events, so it helps to check ahead before visiting.

The gate preserves its original masugata structure with crossing passages, and the two perpendicular routes were not just architectural features but clever defensive tactics. Intruders had to make sharp turns that slowed them down and could confuse their approach.
