Imouto Iwa (Little Sister Rock) on the Left and Ma...


The steep slab that forms a backdrop to Mara Iwa.
The first two routes climb the underside of the right edge of the Casablanca face. Belay on a neat rock podium with a convenient tree right of the gully.

Getting There 

Follow the Kimpu-san highway to the chain across the road. Turn left, cross the river above the dam and follow a path up the big dry stream. After a short while the path cuts left across the stream and disappears into the jungle at a cairn. Follow this path to the foot of Mara Iwa and continue left under the main slab then up to the foot of a cracked wall (from which Casablanca starts). The routes are described from right to left. You can also get here by following a path up and right from Riverside.
