Okinawa Times turns free ad space into lessons in an endangered language

Okinawan is regarded academically as an independent language distinct from Japanese, and the number of speakers declines every year. The Okinawa Times, one of the island's largest newspaper companies, wanted to tackle the problem without lecturing readers.

Open a special newspaper ad space that local small businesses can use free — on one condition: the ad must be written entirely in Okinawan.

Dentsu and the paper created a free ad space for local small businesses under a single rule: only Okinawan could be used. Ten businesses took part, producing ten newspaper ads with 100% Okinawan copywriting and original illustrations, and the project continued with an exhibition of posters and everyday goods all written in Okinawan.

The ten ads put the endangered language back into the public pages thousands read daily, drawing attention across generations and demonstrating that Okinawan could carry local brand communication. The campaign won the Print & Publishing Grand Prix at Spikes Asia 2021 and was a Cresta Awards finalist the year before.

Okinawan is academically regarded as an independent language, distinct from Japanese, and its speaker numbers fall every year. Since 2009 UNESCO has listed it as endangered. The Okinawa Times, one of the island's largest newspaper companies, wanted to act — but a language dies of neglect, not of missing campaigns, so readers needed to meet it again in daily life.

The answer was an ad-space rule rather than a slogan. Dentsu and the paper opened a special section where local small businesses could advertise for free, on one condition: the ad must be written 100% in Okinawan. Ten businesses accepted, and the resulting ads paired Okinawan copywriting with original illustrations across ten newspaper pages.

The project then moved off the page: an exhibition displayed posters and a range of goods written entirely in Okinawan. Together the newspaper ads and the physical objects placed the language back in contexts where ordinary people — and local brands — encounter it every day.

The work was recognised with the Print & Publishing Grand Prix at Spikes Asia 2021 and named a Cresta Awards finalist in 2020, and its idea — giving away inventory to make endangered copy commercially attractive — became a reference for language-preservation efforts in the region.

Free ad space gave ten small businesses a direct reason to commission Okinawan copy, turning preservation from a civic duty into a commercial benefit.

Newspaper ads appear in the flow of everyday reading, so the language returned to public life without a single lecture about saving it.

Ten varied local advertisers showed Okinawan working across real categories — food, services, shops — rather than in one heritage poster.

The exhibition extended the moment beyond the newspaper into posters and goods, letting people hold the language in their hands.

To revive a language nobody speaks, attach it to something people already do daily — commerce: when Okinawan became the price of free advertising, businesses practised it in front of readers.

Language Sanctuary became one of Dentsu Tokyo's flagship civic works of 2019–2021, contributing to the agency's network-of-the-year tallies at ADFEST 2020 and Spikes Asia 2021, where the campaign itself took the Print & Publishing Grand Prix. The mechanism — rule-bound free media space as a preservation tool — was widely shared as a model for endangered languages elsewhere in Asia.
