The Edo Period (the "no wars" period) sounds rather like an authoritarian attempt at Utopia.
A GD analysis would probably show that the generational movements (phases) were played out in a modified form within this "pocket universe".
From:
https://en.wikipedia.org/wiki/Edo_period :
From the outset, the Tokugawa attempted to restrict families' accumulation of wealth and fostered a "back to the soil" policy, in which the farmer, the ultimate producer, was the ideal person in society.
Despite these efforts to restrict wealth and partly because of the extraordinary period of peace, the standard of living for urban and rural dwellers alike grew significantly during the Tokugawa period.

A struggle arose in the face of political limitations that the shōgun imposed on the entrepreneurial class. The government ideal of an agrarian society failed to square with the reality of commercial distribution. A huge government bureaucracy had evolved, which now stagnated because of its discrepancy with a new and evolving social order. Compounding the situation, the population increased significantly during the first half of the Tokugawa period.

Drought, followed by crop shortages and starvation, resulted in twenty great famines between 1675 and 1837. During the Tokugawa period, there were 154 famines, of which 21 were widespread and serious.[22] Peasant unrest grew, and by the late 18th century, mass protests over taxes and food shortages had become commonplace. Newly landless families became tenant farmers, while the displaced rural poor moved into the cities. As the fortunes of previously well-to-do families declined, others moved in to accumulate land, and a new, wealthy farming class emerged. Those people who benefited were able to diversify production and to hire laborers, while others were left discontented. Many samurai fell on hard times and were forced into handicraft production and wage jobs for merchants.

By the 1830s, there was a general sense of crisis. Famines and natural disasters hit hard, and unrest led to a peasant uprising against officials and merchants in Osaka in 1837. Although it lasted only a day, the uprising made a dramatic impression. Remedies came in the form of traditional solutions that sought to reform moral decay rather than address institutional problems. The shōgun's advisers pushed for a return to the martial spirit, more restrictions on foreign trade and contacts, suppression of rangaku, censorship of literature, and elimination of "luxury" in the government and samurai class. Others sought the overthrow of the Tokugawa and espoused the political doctrine of sonnō jōi (revere the emperor, expel the barbarians), which called for unity under imperial rule and opposed foreign intrusions.
