South Pacific Study

South Pacific Study is a Japanese periodical that publishes scholarly articles on a diverse range of subjects of relevance to the South Pacific in a very broad sense. The scope of the journal is extremely wide—you'll find articles ranging from analyses of Buddhist missionary activity, to measurements of volcanic SO₂, to the biology of pests, to taxonomic papers. The icing on top is that these articles are freely available online, back to around 2000. Tables of contents and some articles prior to then are also available.
