Yūbikan

The Yūbikan (有備館) is an Edo period structure located in what is now the city of Ōsaki, Miyagi Prefecture, Japan.

It served as a han school for the Date clan of Sendai Domain, and is the oldest existing educational structure in Japan.

Intended to serve as the domain's academy, it burned down and was rebuilt by the third generation head, Date Toshichika and was named Shungakukan (春学館).

The building is in the shoin-zukuri style of architecture, with a single story, plain wooden walls, and a thatched roof.

The Yūbikan and its gardens remained property of the Date clan until 1970, when it was donated to the town of Iwadeyama, which later became part of the city of Ōsaki.
