Kitasato Shibasaburō
Shigekata established a famous Han school, Jishūkan within the campus of Kumamoto Castle in 1755. This school is known for producing many noted scholars in later years such as Yokoi Shōnan, Inoue Kowashi and Kitasato Shibasaburō. It was open to any class of people, if admission was recognized, not only in Kumamoto people but also in other provinces, with scholarships when students were very bright. There was no such system in other Han schools at this time.
