A Tiny Fireproof Library Named for a Scholar's Pen Name
At the northwestern corner of the Takano grounds in Mizusawa stands a small earthen-walled storehouse facing south, no more than about four square metres inside. Its name carries the memory of the family's most famous member: Zuiko was the pen name of Takano Choei, the Edo-period scholar of Dutch learning, and the building was called the Zuiko Bunko, the Zuiko Library. It is romanized as Zuigo Library in the national register.
Built in 1932, the storehouse was entered onto the national register of Tangible Cultural Properties in August 2024, together with three other buildings on the same site.
Who Was Takano Choei
Takano Choei was born in Mizusawa in 1804 and spent his boyhood in this compound before leaving for Edo in his late teens. Adopted by his uncle Takano Gensai, a physician of Dutch-style medicine, he later studied under Philipp Franz von Siebold in Nagasaki. He wrote a first Japanese work on physiology and a practical treatise on famine relief. When he criticized the shogunate's handling of the Morrison Incident, he was caught up in the 1839 suppression of Western-studies scholars, sentenced to lifelong imprisonment, and later escaped, continuing his translations in hiding until his death in 1850. In his home region he is remembered as one of the three great figures of Mizusawa, alongside the statesmen Goto Shimpei and Saito Makoto.
The former Takano residence next door, where Choei grew up, was designated a Historic Site in 1933. The following decade the family built this little library and gave it his pen name.
A Storehouse Built for Security
Small as it is, the Zuiko Bunko was made to protect. It is a dozo, a thick earthen-walled storehouse, gabled and roofed in pantile, its outer walls finished in mortar. The single interior room has a mortar-finished earth floor, and toward the north side sits a safe intended to hold materials connected with Choei. The front carries a copper-clad double door, and the windows on both sides are fitted with iron grilles. Every element speaks of an effort to guard what was kept inside from fire and theft.
The register recognizes the building for its part in the historic landscape of the district. A collection of Important Cultural Property materials relating to Choei is now held at the Takano Choei Memorial Museum elsewhere in the city, but this small storehouse remains a physical record of a family determined to safeguard the legacy of its scholar.
