Tenmei famine

What Happened

The Tenmei famine (天明の大飢饉, Tenmei no daikikin) was a nationwide food crisis that struck Japan between 1782 and 1788. It is counted among the four great famines of the Edo period (1603–1868), and it was the deadliest of them. The disaster unfolded during the Tenmei era (1781–1789), which gave the famine its name, and it occurred under two successive shoguns: Tokugawa Ieharu (徳川家治, 1737–1786) and his successor Tokugawa Ienari (徳川家斉, 1773–1841).

The famine began in 1782, in what was still the ninth year of the preceding An'ei era (安永, あんえい), before the era name changed to Tenmei. Over the following six years, harvests failed repeatedly across large parts of Japan, food prices climbed beyond the reach of ordinary households, and death from starvation and disease spread through both countryside and city.

Background

Edo-period Japan was a largely agrarian society, and its food supply depended on rice harvested each autumn. When the weather turned against the harvest for several years in a row, the stored reserves of villages and domains were exhausted, and there was no national system capable of moving enough grain to where it was needed.

The 1780s brought exactly that kind of sustained meteorological disaster. Cold, wet summers and volcanic ash in the atmosphere damaged rice crops year after year, and the failure was not confined to one region. Because the famine stretched across the whole of Japan, hard-hit areas could not be relieved by imports from neighbours who were themselves short of food.

The crisis also exposed the limits of the Tokugawa shogunate's response. The government's priority was the stability of the warrior class and the great cities, not the survival of poor farmers, and relief measures were slow and uneven. Many peasants abandoned their land and fled toward towns in search of food, which in turn disrupted the agricultural base that would have to produce the next harvest.

Why It Mattered

The Tenmei famine killed more people than any other famine of Japan's early modern period. The death toll was compounded by epidemics that swept through weakened populations, and by the collapse of normal village life as households broke apart and farmland was left untended.

The social consequences outlasted the hunger itself. Peasant uprisings and riots multiplied during and after the crisis, as starving communities attacked grain merchants and officials they blamed for hoarding and profiteering. The shogunate's inability to feed its own subjects damaged the legitimacy of Tokugawa rule at a time when its finances were already strained.

The famine also pushed the government toward reform. The senior councillor Matsudaira Sadanobu (松平定信, 1759–1829) launched the Kansei Reforms (寛政の改革, Kansei no kaikaku) from 1787, a programme of austerity, moral discipline and agricultural relief intended to restore the shogunate's finances and prevent a repeat of the catastrophe. The memory of Tenmei shaped how the regime thought about famine for the rest of its existence.

The Name in Japanese

The Japanese name of the famine is 天明の大飢饉, read in kana as てんめいのだいききん, and written in romaji as Tenmei no daikikin.

The name breaks into four parts:

• 天 (てん, ten) — "heaven" or "sky". Here it is the first character of the era name Tenmei.
• 明 (めい, mei) — "bright" or "clear". Combined with 天, it forms 天明 (Tenmei), the era name that covers 1781 to 1789.
• の (no) — the possessive particle, linking the era name to the noun that follows. It corresponds roughly to "of" in English.
• 大 (だい, dai) — "great" or "large", used as a prefix to intensify what follows.
• 飢 (き, ki) — "hunger" or "starvation".
• 饉 (きん, kin) — "crop failure" or "want of food". The two characters together, 飢饉 (ききん, kikin), mean "famine".

So the whole phrase means, literally, "the great famine of Tenmei". Japanese era names (年号, nengō) were chosen from classical Chinese texts and changed for auspicious reasons, and disasters were often named after the era in which they occurred. The same pattern appears in the other great Edo famines, including the Kan'ei famine (寛永の大飢饉, Kan'ei no daikikin) and the Kyōhō famine (享保の大飢饉, Kyōhō no daikikin).

Note that the era name Tenmei began in 1781, one year before the famine is considered to have started, and the famine outlasted the era, which ended in 1789. The name therefore reflects when the disaster was most keenly felt rather than its exact boundaries.

Key Figures

Tokugawa Ieharu (徳川家治, 1737–1786) was the tenth shogun of the Tokugawa shogunate. He was in office when the famine began in 1782 and died in 1786, before it ended.

Tokugawa Ienari (徳川家斉, 1773–1841) succeeded Ieharu as the eleventh shogun and ruled during the final years of the famine. He went on to hold the office for decades, making him one of the longest-serving shoguns in Japanese history.

Emperor Kōkaku (光格天皇, 1771–1840) reigned during the Tenmei era, which spanned 1781 to 1789 and gave the famine its name.

Matsudaira Sadanobu (松平定信, 1759–1829) became senior councillor in 1787, as the famine was drawing to a close, and directed the Kansei Reforms that followed it.
