Ibaraki Province, Japan is the first stage from The Revenge of Shinobi.
Details[]
Deep in the mountains, this is the village of the Oboro-ryu ninjas where Joe Musashi was raised, but it has been left in ruins by the attack of Neo Zeed. The ninja mansion has also been occupied.
The first area is straightforward, while the second area requires the player to explore the building and unlock a secret underground path. At the end the Blue Lobster awaits to confront Joe.
