Nintōjō

The Nintōjō, also known as the Staff of Two Heads in the English version of the anime, is the weapon which Jaken wields. It can produce long streams of flame, and generate large floods of water.

Appearance
It looks like the name it was given. On half of the top of the staff, sits the head of an old man, and on the other sits the head of a once-beautiful woman. Although, it seems the beautiful woman is more of an old woman with silky black hair. The staff is taller than Jaken himself.

Abilities
The Nintōjō doesn't have many abilities. The old man head can spew fire whenever Jaken wishes. When close to the grave of the Inu no Taishō, the old man's head laughs. But when at the wrong place, the beautiful woman shrieks.
