March 29, 1861 (Man'en 2/Bunkyū 1, 19th day of the 2nd month) Bunkyū gannen (文久元年): The new era name of Bunkyū (meaning "Literate Story") was created because of a belief drawn from Chinese astrology that the 58th year of any zodiacal cycle brings great changes. The previous era ended and a new one commenced in Man'en 2.
Events of the Bunkyū era

January 1862 (Bunkyū 1, 12th month): The Bonin Islands (Ogasawara Islands) are re-confirmed as a territory of Japan, following up "discovery" of the islands in Kanbun 10 (1670) and a shogunate expedition to the islands in Enpō 3 (1675).
1862 (Bunkyū 2): The Bunkyū Reforms relax restrictions on daimyōs which had been imposed by former TairōIi Naosuke in the Ansei era.

As Katamori is unavailable, they are instead met by two of his senior retainers.
