Keys

Teru was born the third daughter of Hoshina Masamoto, lord of Kazusa Iino, and at about ten became an adopted daughter of Aizu lord Matsudaira Katataka. Genealogical scrolls, an adoption petition and shogunate notice, seals, a document chest, small sandals, and palanquin fittings show that this was not merely a child moving between relatives. It belonged to daimyo succession planning and the formal relationship between the Hoshina and Matsudaira houses. Before the familiar title “princess,” she was registered and educated as an adopted daughter expected to carry a house’s future, ritual standing, and alliances.

At about eighteen Teru married Nakatsu lord Okudaira Masamoto and several years later returned divorced to the Edo Aizu residence. Lacquered trousseau chests, clothing, incense and cosmetic utensils, a marriage inventory, route chart, baggage tags, and sealed return papers reveal marriage between daimyo houses as an organized transfer of property, attendants, messages, and rank. The divorce should not be reduced to her personality or health, since succession and household interests also structured it. Returned chests were not only signs of a failed union; they became material foundations for her renewed place in Aizu’s inner household.

After divorce Teru returned to the Edo Aizu residence. Following the early death of Katamori’s wife Toshihime, Teru occupied the highest-ranking female position around the house and participated in the inner quarters. Storeroom and room keys, ledgers allocating food, cloth, and personnel, sewing boxes, a koto, incense burner, waka papers, inkstone, and letter chest show that the inner quarters were an organization managing many women servants and substantial supplies, not a private salon. Calligraphy, etiquette, incense, music, and poetry served ritual, gifts, mourning, communication, and household order.

After defeat at Toba-Fushimi, Aizu people withdrew from Edo toward Aizu in the second month of 1868, and Teru was among those who moved. A highway map, checkpoint passes, travel chests, bedding rolls, a medicine box, tableware, weather covers, porters, and pack animals show a political crisis transformed into long-distance movement involving relatives, servants, older people, and stores. This was not Teru’s solitary return. It required closing a residence, selecting records and necessities, arranging lodgings, and protecting a traveling household. The same travel equipment soon became part of preparation for siege conditions.

About five hundred women and children entered Tsuruga Castle during the Aizu War. Teru is remembered as their highest-ranking center and a source of morale. Huge cooking cauldrons, rice baskets, ration bowls, bandages, hot water and medicines, torn cloth, bullet molds and lead, water buckets, and wet quilts used against fires show that armed defenders could not sustain the siege alone. Cooking, nursing, ammunition production, fire control, and care for wounded and dead were distributed among many women, children, and officials. Their collective work should not be absorbed into a claim that Teru personally performed or commanded every task.

Aizuwakamatsu preserves letters, a waka poem, and a memorandum sent by Katamori and Teru to Kayano Gonbei before he was executed as the bearer of Aizu’s war responsibility. The poem mourning him through uncertainty between dream and waking, six surviving Matsudaira Teru waka volumes, an inkstone, letter chest, incense burner, memorial tablet, and the Innai family cemetery show that her work did not end with the siege. Poetry stored names and grief across the sixteen years she lived after the war. Loyalty should not beautify the political transfer of blame to one man; the documents keep that death beside the survivors’ long memory.
