"Ru" Gate
The entrance to the gate from the outside is low and the exit is high.
We climb up the stairs to pass through, and we must make a sharp right turn.
Viewed from the outside, it is "Burying Gate"(Uzumi Gate), when viewed from the inside,
it is called "Tunnel Gate" (Ana Mon).
As this gate served a tactical purpose, it is also said to have been the gateway of stealth
which the spies got into and out of.
