01 / Chidōkan
Dismantled to build a school,rebuilt the same way a year later.

In 1858 the 15th lord of Hiji domain, Kinoshita Toshinori (木下俊程), founded Chidōkan (致道館) as the domain school in the second bailey of Hiji Castle. Hoashi Banri (帆足万里), one of the "Three Sages of Bungo," taught here. The building was dismantled in 1950 to make way for a junior high school, then rebuilt the following year, the 100th anniversary of Banri's death. It is the only domain-school building still standing in Oita Prefecture.
