Wotje village is the practical centre of the atoll and the best place to look for World War II remains. Japanese defensive works, old concrete, and traces of the former base sit close to the modern village landscape, where daily life has simply grown around them.
The remains are not presented as a formal battlefield park. Go with someone local who can point out what is worth seeing, and remember that much of the land is used by families, schools, churches, and the community.
