Kamiyama Satellite Office Project — Reversing Rural Depopulation Through Remote Tech Work

Kamiyama is a mountain town of roughly 5,000 residents in Tokushima Prefecture, Japan. In 1999 the local nonprofit Green Valley, led by Shinya Ominami, began renovating the town's empty houses (akiya) and using prefecture-built fibre-optic infrastructure — originally installed for disaster-recovery communications — to host visiting artists and, from 2010, Tokyo-headquartered tech firms. Business-card management company Sansan opened the area's first corporate satellite office in Kamiyama in 2010, followed by others including Engawa Corporation (around 15 employees, opened 2013), demonstrating that Tokyo-salary, Tokyo-role jobs could run from a rural mountain town over fibre. Tokushima Prefecture and Kamiyama's town government then formalised and scaled the approach: in March 2012 the prefecture launched its 'Tokushima Satellite Office Project' to replicate the model in other depopulating municipalities.

By October 2020, the Japan External Trade Organization (JETRO) recorded 72 companies — spanning ICT, video and design firms — operating satellite offices across 16 municipalities in Tokushima Prefecture, and a fiscal-year-2019 survey ranked Tokushima second nationally (after Hokkaido) for satellite-office attraction, with 67 companies across 14 municipalities. At the town level, Euronews reported that 2011 was the first year in decades Kamiyama's population grew rather than shrank, even as Japan's national population began its own decline, and that by the early 2020s around 70% of children enrolled in the town's nursery came from families who had relocated there — evidence the effect reaches beyond single tech workers to their households.

The scale of the turnaround should not be overstated. Kamiyama's population remains far below its mid-20th-century peak, and the reported 2011 net gain was small in absolute terms (151 people moved in versus 139 who moved out). The dozen or so satellite offices in Kamiyama itself, and the roughly seventy across the wider prefecture, represent tens of jobs and companies, not hundreds — modest relative to the scale of Japan's rural depopulation problem, and the model relied on a specific combination of assets (existing disaster-recovery fibre, one committed NPO founder, and low real-estate costs) that is not automatically transferable. Even so, the project is unusual for having predated the post-pandemic remote-work boom by roughly a decade and having been formally scaled by prefectural government to 16 municipalities rather than remaining a single-town curiosity.
