Yamamoto Bunker

Map Room Chambers
Probably the most impressive feature of the bunker are the two circular map room chambers, both are identical and on opposite sides of the bunker, up narrow staircases. One chamber suffers from some contemporary graffiti and water damage, although even in that room, the maps are still in good shape.

Ceiling Map
Overhead, there is a circular map of Rabaul, and the entire Gazelle Peninsula area, with compass points and coordinates drawn out in every direction from the bunker. Distances and coordinates are drawn out, presumably for Anti-Aircraft and searchlight direction.

Harbor, Airfield and Strategic Wall Maps
On each wall are a number of other maps. One is a larger strategic area map that shows all of New Britain, New Ireland and mainland New Guinea. Another map is a detail of the harbor. Another map shows all of the Rabaul Area airfields: Vunakanau, Laukuna, Rapopo and Tobera.

"RR"
Below the map, is Japanese writing in a table with grid locations and coordinates. The letters "RR" are the Japanese designation for "Rabaul"
