WWII Underground Japanese Tunnels & Kokopo War Museum: Private Expert Tour

Descend into the vast network of hand-dug Japanese wartime tunnels that honeycomb the Rabaul hills, then visit the Kokopo War Museum's haunting collection of Pacific theatre artefacts. This is one of the great WWII sites of the entire Pacific — raw, authentic, and almost entirely unknown to the wider world.

What to expect

You enter tunnel complexes large enough to shelter aircraft, submarines and thousands of troops, torchlight revealing rusting machinery, ammunition caches and Japanese signage still intact. Your guide weaves personal family stories into the military history, bringing the 1942–45 occupation viscerally to life. The Kokopo War Museum follows, with Japanese midget submarines, aircraft wrecks and Allied memorabilia in an open-air setting of quiet dignity. The Rabaul War Cemetery, immaculately kept, provides a contemplative close.
