Bunkyū

Overview

Bunkyū (文久) was a Japanese era name (年号, nengō; "year name") that followed Man'en and preceded Genji. The era spanned from March 29, 1861, to March 26, 1864, during the late Edo period (1603–1868). The reigning emperor throughout the Bunkyū era was Kōmei-tennō (孝明天皇).

The Bunkyū era sits in a turbulent stretch of Japanese history, when the Tokugawa shogunate faced mounting internal and external pressures. The era's three years saw the country move closer to the political upheaval that would culminate in the Meiji Restoration of 1868.

What Defined the Era

The Bunkyū era was defined by the collision between the shogunate's efforts to manage foreign relations and the growing domestic movement to reject foreign influence. The previous era, Man'en, had ended in the shadow of the assassination of Ii Naosuke, the shogunate's chief minister, in 1860. That killing, carried out by samurai opposed to his policies of opening Japan to foreign trade, set the tone for the years that followed.

During Bunkyū, the shogunate attempted a series of political accommodations. These included the marriage of Princess Kazu, the emperor's younger sister, to the shōgun Tokugawa Iemochi in 1862, a union intended to strengthen ties between the imperial court and the shogunate. The era also saw the shogunate relax its policy of alternate attendance (sankin kōtai), which required feudal lords to spend alternating years in Edo. This concession, made in 1862, weakened central control over the domains.

The era's name itself reflected a hope for a return to civility and culture, but the reality was increasingly violent. Anti-foreign sentiment, expressed in the slogan sonnō jōi ("revere the emperor, expel the barbarians"), led to attacks on foreigners and on shogunate officials. The British legation in Edo was burned in 1863, and the shogunate's decision to withdraw from the policy of opening ports only deepened the crisis.

Key Events

The Bunkyū era opened with the shogunate still reeling from the assassination of Ii Naosuke and the political chaos that followed. In 1862, the marriage of Princess Kazu to Shōgun Iemochi took place, a symbolic attempt to reconcile the imperial court with the shogunate.

In the same year, the shogunate issued the edict relaxing the alternate attendance system. This measure reduced the financial burden on the feudal lords but also loosened the shogunate's grip on them. Domain leaders, particularly from Satsuma and Chōshū, began to assert greater independence.

In 1863, the shogunate, under pressure from the imperial court, issued an order to expel foreigners. The order was largely symbolic and unenforceable, but it encouraged further attacks. That year, the British legation in Edo was set ablaze. In the same year, Chōshū domain forces fired on foreign ships passing through the Strait of Shimonoseki, an act that would draw a punitive international response after the Bunkyū era ended.

The era closed in March 1864 with the proclamation of a new era name, Genji. The change of era name was a routine act of imperial authority, but it did nothing to calm the country. Within months, the shogunate would face the Kinmon incident and the first Chōshū expedition, both of which lay just beyond the Bunkyū boundary.

The Name in Japanese

The era name is written 文久 in Japanese. Its kana reading is ぶんきゅう, and its romaji form is Bunkyū.

The name consists of two kanji:

• 文 (ぶん, bun): meaning "writing," "literature," "culture," or "civilisation." This character carries a strong sense of refinement and scholarly pursuit. It appears in words like 文学 (bungaku, "literature") and 文化 (bunka, "culture").

• 久 (きゅう, kyū): meaning "long time," "long-lasting," or "eternal." This character conveys duration and endurance. It appears in words like 永久 (eikyū, "permanence") and 久しい (hisashii, "long-standing").

Together, 文久 suggests something like "enduring civilisation" or "long-lasting culture." The choice of this name reflected a desire for a peaceful and cultured era, an aspiration that the events of 1861–1864 would decisively disappoint. The reading Bunkyū follows the standard on-yomi (Chinese-derived reading) for both characters, ぶん for 文 and きゅう for 久.

How the Era Name Works

A Japanese era name, or nengō (年号), is a system of naming years that Japan adopted from China. Each era name is proclaimed by the emperor and remains in effect until a new era is declared. The era name is used to count years within that era: the first year of Bunkyū is Bunkyū 1, the second is Bunkyū 2, and so on.

The era name changes for several reasons. A new emperor's accession normally triggers a new era, but era names can also change on auspicious or inauspicious events, such as natural disasters, military victories, or the start of a new sexagenary cycle. The Bunkyū era was proclaimed in 1861, and it ended in 1864 when the new era name Genji was announced.

The nengō system remained the official method of dating in Japan until 1873, when the Gregorian calendar was adopted for civil use. Even then, the era name system continued. It remains in use today: the current era, Reiwa, began in 2019 with the accession of Emperor Naruhito. For students of Japanese, era names are more than historical trivia; they appear constantly in documents, dates, and cultural references, and knowing how to read them is essential for navigating Japanese history and everyday life.
