Vanuatu
Every February, men march with bamboo rifles and USA painted red across their chests.
At Lamakara, above Sulphur Bay, cane huts ring a ceremonial ground where flags rise on 15 February and barefoot ranks drill with wooden guns. The letters USA are painted in red on bare chests. Across the valley, Yasur rumbles; believers hold that John Frum lives inside the volcano.
John Frum is a living faith, and it is older than the clichés about it. The movement rose on Tanna in the late 1930s, before the vast American wartime presence, when the figure of John Frum called islanders back to their lands, their kava and their dancing against mission prohibition; the material abundance American servicemen later brought to the islands was folded into a faith already standing. Its holiest day is 15 February, when devotees from across Tanna gather at Lamakara for military-style drill blended with kastom dance, red crosses, raised flags and song. Followers hold that John Frum is a spirit who dwells in Yasur and moves between the volcano and America, and the movement has endured into settled institutions rather than fading as outsiders long predicted. Visits are arranged through local contacts, and the visit worth making is the one spent listening: these are beliefs a community holds seriously, not a show staged about the past.
Solo
Visits are arranged through a local contact; come ready to listen; explanations given directly, in Bislama or French, will upend easy assumptions about how faith works.
Couple
Attend the public ceremony and give worshippers room outside invited areas, then talk it over across kava as Yasur glows in the dark.
Friends
Agree a photography approach before arriving and keep the group unobtrusive; the ceremony rewards patience more than cameras.
Lenakel's market tables are a culinary walk through Tanna-grown produce; arrive hungry and graze whatever the stalls are cooking that morning.
Tanna's volcanic soil grows coffee prized for its smooth flavour, poured at hilltop bungalows after plates of the day's fish and garden vegetables.
