Koshiro Fujita

水戸藩 / 1842-1865

Trace Koshiro Fujita through the physical settings of Mito domain education, the improvised headquarters on Mount Tsukuba, the Nakaminato furnace and cannon, post roads and camps, winter marching equipment, and the herring-fertilizer warehouses of Tsuruga. These places and objects show how inherited political language became organization, logistics, civil war, surrender, confinement, and execution.

Mito and Edo

Mount Tsukuba

Raised a Force with More than Sixty Companions


The demand for immediate exclusion expanded into a large force and drew domain and shogunate pursuit. This stage of Koshiro Fujita's life becomes clearer when the event is read with the places, objects, and documents associated with Mount Tsukuba, revealing both its immediate setting and the conditions that shaped the next decision.

Nakaminato and northern Kanto

Entered a Civil War of Cannon, Roads, and Requisition


Fighting and movement exposed problems of artillery, finance, supplies, discipline, and civilian coercion. This stage of Koshiro Fujita's life becomes clearer when the event is read with the places, objects, and documents associated with Nakaminato and northern Kanto, revealing both its immediate setting and the conditions that shaped the next decision.

Shimonita, Wada Pass, and Echizen

Marched West with Takeda Kounsai through Snow


Nearly one thousand people sought an appeal through Yoshinobu, who instead took command of the pursuit. This stage of Koshiro Fujita's life becomes clearer when the event is read with the places, objects, and documents associated with Shimonita, Wada Pass, and Echizen, revealing both its immediate setting and the conditions that shaped the next decision.

Tsuruga

Confined in Warehouses and Executed


After surrender and transfer to shogunate custody, Koshiro was held under severe conditions and executed.

What Shaped Koshiro Fujita

Receiving His Father's Ideas in an Institutional School ink painting
01

Kodokan Lecture Hall

Kodokan stood in the third enclosure of Mito Castle and combined formal halls with grounds for sword, spear, riding, and other martial disciplines. Fujita Toko, Koshiro's father, helped shape the school and its demand that study lead to public action. Koshiro therefore encountered loyalist and exclusionist arguments not only as family teaching but inside an institution that trained domain personnel, connected scholarship to administration, and placed political judgment beside physical discipline.

Mount Tsukuba Shrine Buildings

Shrine buildings, stone approaches, wooded paths, and temporary shelters made Mount Tsukuba a recognizable meeting place and an improvised headquarters. In March 1864 Koshiro and a little over sixty companions raised their force there. The setting mattered because declarations alone could not sustain a rising: assignments, lodging, food, weapons, and messengers had to be arranged. As recruitment expanded, the mountain camp became the starting point of a violent conflict within Mito domain.

Nakaminato Reverberatory Furnace

The reverberatory furnace at Nakaminato was a brick industrial installation for melting iron and casting artillery. Mito City Museum materials pair the destroyed furnace site with the cannon known as Ki. Together they show that the domain conflict required workshops, refractory brick, charcoal, molds, transport, powder, and trained labor. Koshiro's campaign was not only a sequence of speeches and vows; it became tied to heavy manufactured objects that had to be produced, moved, supplied, and aimed.

Reheishi Highway

The Tsukuba force moved along the Reheishi highway and established a headquarters on Mount Ohira. Post towns supplied rooms, food, horses, information, and routes, but they also exposed civilians to demands for money and provisions. Abusive collection by parts of the force damaged local support. Reading the campaign through roads, inns, and storehouses makes Koshiro's movement a logistical occupation of shared infrastructure rather than a heroic march across an empty map.

Straw Capes

The westward force altered its route to avoid a major clash on the Nakasendo and entered Echizen in December snow. Straw capes, hats, sandals, pack ropes, cooking kettles, and covers for firearms were expendable equipment that determined how far people could move. In a column approaching one thousand, wet footwear, food, shelter, and damaged loads could slow political purpose to a crawl. The appeal to Hitotsubashi Yoshinobu was carried by bodies and objects worn down on mountain roads.

From Temple Confinement to Fertilizer Stores and Execution ink painting
06

Tsuruga Herring Warehouses

After surrender, the force was first confined in three Tsuruga temples. Once transferred to shogunate control, prisoners were packed roughly fifty at a time into sixteen warehouses normally used for herring fertilizer. Ventilation and sanitation were poor, and illness spread before executions at Raihoji-no. The present Takeda Kounsai graves also record a later material history: local residents continued memorial rites and rebuilt several burial mounds into a larger protected grave site.
