脱成長 ジャパンCultivating a rich life from Japanese roots.

HISTORICAL CONTEXT

Degrowth, seen from Japan.

Degrowth is often thought of as a European academic movement arriving in Japan from outside. This framing gets things backwards. Degrowth, in its simplest form, is the proposition that human societies can flourish without perpetual economic expansion: that sufficiency is not deprivation, that communities and ecosystems are partners rather than opposites, and that the good life does not require infinite growth. Japan has been living versions of this proposition for centuries, and in some ways, it is living one right now.

The History: A culture of sufficiency

Long before the word "degrowth" existed, Edo-period Japan (1603–1868) had developed one of the most sophisticated examples of a functioning low-throughput civilization in recorded history — and it did so in response to near-collapse from environmental degradation. "The fact that it did not," says historian Azby Brown, "is what makes it such an instructive example" (Brown 2012). In this society, cities of over a million people ran on closed material loops with modular architecture. Forests were managed across generations. Coastal and agricultural landscapes — known as satoyama and satoumi — were maintained through community stewardship that produced higher biodiversity than either extraction or neglect alone. This is not a fairytale or a dream: it was the historically documented reality in Japan merely six generations ago.

The Present: A country already in post-growth

In an important sense, Japan is also already living the degrowth transition — not by choice, but by circumstance. It is among the first developed nations to experience sustained economic and demographic decline simultaneously. And despite decades of stagnation, Japan continues to perform comparably well on international quality-of-life measures, ranking in the top third of OECD Better Life Index indicators, with particular strengths in health, safety, and subjective wellbeing (Komatsu et al., 2022). This matters enormously. It is real-world evidence that economic growth and human flourishing can come apart — that a society can stop growing and still, by many measures, be doing well.

Yet Japan's political response to stagnation has largely been to chase growth back. Rural communities experiencing depopulation are framed as inefficient rather than as pioneers of a different way of living. The question degrowth asks — what if the goal isn't to restart growth, but to make the post-growth transition just and livable for everyone? — remains largely unasked in mainstream Japanese policy.

Where Degrowth Japan comes in

Degrowth Japan exists at this intersection: between a cultural heritage that already knows sufficiency, and a present moment that urgently needs a framework for it. We hope to connect Japan's living traditions of ecological stewardship and community resilience with the global degrowth movement through community care and shared learnings — and to ask what a planned, equitable, democratic post-growth transition might look like in one of the places most suited to it.

ABOUT THE NAME

"Eh? Aren't you the Tokyo Snails?"

Tokyo Snails is our local community group operating within the greater Tokyo area — monthly meetups, neighborhood workshops, hands-on gatherings at street level. Warm, informal, Japanese-language first.

Degrowth Japan is the institutional face of the same collective. Our additional purpose is to create the conditions for like-minded organizations to connect across Japan for mutual aid and shared support — and to build relationships with international degrowth institutions and networks, including the IDN.

Same people. Different roles.
