Yamamoto's Bunker is part of Rabaul's dense Second World War landscape, a Japanese defensive site associated in local telling with Admiral Isoroku Yamamoto. The bunker sits near the old New Guinea Club and Rabaul Museum area, where wartime traces still sit close to the volcanic, half-ruined townscape.
The history is complicated and some claims around Yamamoto should be treated with caution, but the site is still worth seeing for travellers interested in the Pacific war. Rabaul's appeal lies in this layering of volcano, colonial town, and military remains; the bunker is one piece of that larger story.
