Edo society refers to the society of Japan under the rule of the Tokugawa Shogunate during the Edo period from 1603 to 1868.

Edo society was a feudal society with strict social stratification, customs, and regulations intended to promote political stability. The Emperor of Japan and the kuge were the official ruling class of Japan but had no power. The shōgun of the Tokugawa clan, the daimyō, and their retainers of the samurai class administered Japan through their system of domains. The majority of Edo society were commoners divided into peasant, craftsmen, and merchant classes, and various "untouchable" or Burakumin groups.

The Tokugawa shogunate ruled by dividing the people into four main categories. Older scholars believed that there were Shi-nō-kō-shō (士農工商, Four Occupations) of "samurai, peasants (hyakushō), craftsmen, and merchants" (chōnin) under the daimyo, with 80% of peasants under the 5% samurai class, followed by craftsmen and merchants.^[3] However, various studies have revealed since about 1995 that the classes of peasants, craftsmen, and merchants under the samurai are equal, and the old hierarchy chart has been removed from Japanese history textbooks. In other words, peasants, craftsmen, and merchants are not a social pecking order, but a social classification.^[1][4][5]

The bakumatsu from 1853 on led to growing opposition to the Edo system and it was dismantled after the Meiji Restoration in 1868.

Feudalism, social stratification, and explicit fine-grained ranking of people existed in Japan long before the Edo period, beginning with attempts as far back as the Taika Reforms in 645 AD, initiating the Ritsuryō legal system that was modeled from Chinese Tang dynasty legal code. The reforms were following a major and devastating coup d'etat attempt by Soga no Emishi, with the events not only exterminating entire clans, but tearing apart a gaping hole in the Japanese indigenous religion, Ko-Shintō, paving the way for a Buddhist-Shinto syncretism of religion.

The Taika Reforms were the "legal glue" deemed necessary to thwart future coup d'etat attempts, and the Ritsuryō system led to the formation of castes in Japan. Nevertheless, frequent warfare and political instability plagued Japan in following centuries, providing countless opportunities to usurp, bend, and mobilize positions within social ranks. Even the ranks themselves, especially military ranks, became more respected if only out of necessity. Confucian ideas from China also provided the foundation for a system of strict social prescriptions, along with political twists and turns of the day.

The Ashikaga Shogunate established a loose class system when it ruled Japan as a feudal shogunate during the Muromachi period from 1338 to 1573. The final collapse of the Ashikaga worsened the effects of the Sengoku period (or "Age of Warring States"), the state of social upheaval and near-constant civil war in Japan since 1467. Tokugawa Ieyasu of the Tokugawa clan and his Eastern Army emerged victorious after the Battle of Sekigahara in 1600, defeating the Western Army of Toyotomi Hideyori, ending the Sengoku civil wars.

Ieyasu founded the Tokugawa Shogunate as a new feudal government of Japan with himself as the shōgun. However, Ieyasu was especially wary of social mobility given that Toyotomi Hideyoshi, one of his peers and a kampaku (Imperial Regent) whom he replaced, was born into a low caste and rose to become Japan's most powerful political figure of the time. The Tokugawa clan sought to eradicate any potential opposition across Japanese society from top-to-bottom to consolidate their rule.

The Emperor of Japan was the official ruler of Japan at the very top of the Tokugawa class hierarchy. However, the Emperor was only a de jure ruler, functioning as a figurehead held up as the ultimate source of political sanction for the shōgun's authority. The Emperor and his Imperial Court located in Kyoto, the official capital of Japan, were given virtually no political power but their prestige was invincible.

The court nobility, the kuge, were the civil aristocracy of Japan. Similar to the Emperor, the kuge were incredibly prestigious and held significant influence in cultural fields, but wielded very little political power and served functions only for symbolic purposes.

The shōgun was the de facto ruler of Japan. Officially, the shōgun was a title for a prominent military general of the samurai class appointed by the Emperor with the task of national administration. Successive shoguns held the highest or near-highest court ranks, higher than most court nobles. They were made Shō ni-i (正二位, Senior Second Rank) of court rank upon assuming office, then Ju ichi-i (従一位, Junior First Rank), and the highest rank of Shō ichi-i (正一位, Senior First Rank) was conferred upon them upon their death.^[2] In reality, the shōgun was a military dictator with only a nominal appointment from the Emperor who held the ultimate political power in Japan, controlling foreign policy, the military, and feudal patronage. The shōgun was a hereditary position held by members of the Tokugawa clan who were direct descendants of Tokugawa Ieyasu. The shōgun was based in the Tokugawa capital city of Edo, Musashi Province, located 370 kilometres (230 mi) east of Kyoto in the Kanto region, and ruled Japan with his government, the bakufu. The Tokugawa shogunate established that the court ranks granted to daimyo by the imperial court were based on the recommendation of the Tokugawa shogunate, and the court ranks were used to control the daimyo.^[2]

The daimyō were samurai feudal lords. The daimyō were high-ranking members of the samurai, and, similar to the shōgun, held most of the real political power in Japan. The daimyō was responsible for administration through their large personal domains, the han, which served as unofficial administrative divisions in tandem with the legal provinces. A daimyō was determined if a samurai's domain was assessed at 10,000 koku (50,000 bushels) or more under the Tokugawa kokudaka system of taxation.

The daimyō held significant autonomy but the Tokugawa policy of sankin-kōtai required them to alternate living in Edo and their domain every year. The daimyō were separated into the shinpan, relatives of the Tokugawa, the fudai daimyō, who filled the ranks of the Tokugawa administration, and the tozama daimyō, those who only submitted to the Tokugawa after the Battle of Sekigahara.

The Tokugawa government intentionally created a social order called the Four divisions of society (shinōkōshō) that would stabilize the country. The new four classes were based on ideas of Confucianism that spread to Japan from China, and were not arranged by wealth or capital but by what philosophers described as their moral purity. By this system, the non-aristocratic remainder of Japanese society was composed of samurai (士, shi), farming peasants (農, nō), artisans (工, kō) and merchants (商, shō).^[6]: 7

Samurai were placed at the top of society because they started an order and set a high moral example for others to follow. The system was meant to reinforce their position of power in society by justifying their ruling status. However, the shinōkōshō does not accurately describe Tokugawa society as Buddhist and Shinto priests, the kuge outside of the Imperial Court, and outcast classes were not included in this description of hierarchy.^[6]: 7

In some cases, a poor samurai could be little better off than a peasant and the lines between the classes could blur, especially between artisans and merchants in urban areas. Still, the theory provided grounds for restricting privileges and responsibilities to different classes and it gave a sense of order to society. In practice, solidified social relationships in general helped create the political stability that defined the Edo period.^{[7]: 135–136}

Samurai were the noble [warrior] class in Japan. The samurai constituted about 10% of the population and functioned as soldiers in the employment of a lord in a master-warrior feudal relationship. Other classes were prohibited from possessing long swords such as the tachi or katana, and carrying both a long sword and a short sword became the symbol of the samurai class. However, their services were in limited demand as the Edo period was largely free from both external threats and internal conflicts.

Instead, the samurai maintained their fighting skills more as an art form than to fight. Samurai were paid a stipend from their lord, limiting their ties to the economic base. In addition, samurai could not own land, which would have given them income independent from their duty. Samurai generally lived around their daimyō's castle, creating a thriving town or city environment around the middle of a domain.

There were social stratifications within the samurai class: upper-level samurai had direct access to their daimyō and could hold his most trusted positions, with some achieving a level of wealth that allowed them to retain their own samurai vassals. Mid-level samurai held military and bureaucratic positions, and had some interactions with their daimyō if needed. Low-level samurai could be paid as little as a subsistence wage and worked as guards, messengers and clerks.

Positions within the samurai class were largely hereditary and talented individuals could not rise above a few social steps beyond their birth.^[6]: 30

According to Confucian philosophy, society could not survive without agriculture.^[6]: 45 Life for rural peasants focused on farming in and around their villages. Peasants rarely moved beyond their villages, and journeys and pilgrimages required a permit, but young people occasionally sought seasonal employment outside of their village. As a result, people were highly suspicious of outsiders. Social bonding, critical to the survival of the whole village, was also reinforced through seasonal festivals. Villages were highly collective; there were strong pressures to conform and no room to deviate from custom.^[6]: 12 Though there were conflicts, they were seen as disruptive to the village and order and were to be limited as much as possible.^[6]: 13

The peasant class owned land, but rights to tax this land were given to the local daimyō. Peasants worked to produce enough food for themselves and still meet the tax burden. Most agriculture during this time was cultivated by families on their own land in contrast to the plantation or hacienda model implemented elsewhere.^[6]: 45 Peasants could amass relatively large amounts of wealth but remained in the same class because of their association with the land. Wealthier families and those that held their own land and paid taxes were held in much higher regard and had more political influence in village matters. However, the survival of the village depended on every household cooperating to meet the tax burden and overcome natural disasters such as famines. During the reign of the third shōgun, Tokugawa Iemitsu, farmers were not allowed to eat any of the rice they grew. They had to hand it all over to their daimyō and then wait for him to give some back as charity.^{[citation needed]}

Artisans typically lived in urban areas, and by 1800, as much as 10% of the population of Japan may have lived in large urban areas, one of the highest levels in the world at the time.^[6]: 43 The daimyō and their samurai did not produce any goods themselves, but they used the tax surplus from the land to fuel their consumption. Their needs were met by artisans, who moved to be around the castles and were restricted to living in their own quarter.

Merchants grew increasingly powerful during the Edo period, in spite of their social standing, and the top merchants commanded a certain amount of respect, with Osaka and later Edo having concentrations of the merchant class.

Wealthy merchant houses arose to organize distributors and hold legal monopolies. As their wealth grew, merchants wanted to consume and display their wealth in the same manner as the samurai, but laws prevented them from doing so overtly. Still, their consumption combined with that of the samurai served to reinforce the growth of the merchant and artisan classes.

Underneath the merchant class were various communities and levels of outcasts not included within the official Tokugawa class system. These people were "untouchables" who fell outside of mainstream Japanese society for one reason or another, and were actively discriminated against at the societal level.

The burakumin ('hamlet people/village people' or 'those who live in hamlets/villages') were ethnic Japanese people whose occupations were considered impure or tainted by death, such as executioners, undertakers, slaughterhouse workers, butchers, and tanners. These occupations were seen to be kegare (穢れ, 'defilement') in the Shinto religion. In the Edo period, the social stigma of being a burakumin developed into a hereditary status.

Although technically commoners, the burakumin were victims of severe ostracism and lived in their own isolated villages or ghettos away from the rest of the population.

Ethnic minorities in Japan were generally excluded from the class system, though certain individuals in service of the shōgun or daimyō were included. The Tokugawa isolationist policy of sakoku banned most foreigners from entering Japan.

A Japanese woman's life varied immensely according to her family's social status. Women in samurai families were expected to submit to their male heads of household, but as they aged, they could become the ranking household member if their husband died. Children were taught to respect both of their parents, even as adults. Women from the lower classes were much less restricted by social expectations and could play an integral part in the family's business.^[6]: 15 Peasant women were expected to do household chores in the early morning before working in the fields with their male relatives and, regardless of age, were important, working members of their families.

Marriage was not based on romantic attraction. Families tried to use marriage as a way to increase their social standing or, among wealthier groups, to increase one's influence and holdings. Most often, however, marriage occurred between two families of equal status.^[6]: 14 Female virginity at marriage was important in the samurai classes; it was much less important to the lower classes.^[6]: 14 After marriage, women were restricted from taking additional sexual partners. Males of the upper classes, however, were able to take concubines and have relations with unmarried women. Divorce was common, and a woman from a poor household could very easily leave her husband and return to her original family.

The foundation of Edo society was its stable social order, but changes to Japanese society over the next two centuries began to challenge the Tokugawa system. Increasing urbanization and rising consumerism saw wealth become concentrated outside of the samurai class, and their fixed stipends did not increase despite the rising cost of commodities. The increasingly burdensome cost of proper social etiquette led many samurai to become indebted to wealthy urban merchant families. The merchants, in turn, were restricted from showing their wealth for fear of violating the laws that restricted privileges to the samurai class. That created deepening resentment but also increasing interdependence between the two classes.^[7]: 159

Some Japanese scholars began to question the Confucian beliefs that provided the foundation of Edo society.^[6]: 57 Additionally, numerous changes in rural areas increasingly challenged the Tokugawa system. New technology which increased productivity allowed some peasant families to produce a surplus of food, creating a disposable income that could be used to support ventures beyond farming. Some peasants also became indebted to their wealthier neighbors, and more families lost ownership of their land. This sparked resentment that sometimes erupted into violence towards landlords and the village elite.

In 1853, the beginning of the bakumatsu saw Edo society increasingly questioned by Japanese people when Western powers used their technological superiority to force concessions from the Tokugawa in the Unequal treaties. Many Japanese people, including members of the samurai, began to blame the Tokugawa for Japan's "backwardness" and subsequent humiliation. A modernization movement which advocated the abolition of feudalism and return of power to the Imperial Court eventually overthrew the Tokugawa Shogunate in the Meiji Restoration in 1868.

The new Meiji government of the Empire of Japan soon abolished the Tokugawa class system that had characterized Edo society. The kuge and daimyo classes were merged into the kazoku aristocratic class with class privileges which formed the Meiji oligarchy. Most remaining samurai that did not become kazoku were designated as shizoku, a distinct class without class privileges that was purely a title on the government register. Commoners and the burakumin were merged into a single commoner class without restrictions or distinction for their occupation, though burakumin continued to face discrimination similar to Edo society.
