Appointed as an instructor at the clan's school, Meirinkan.

Yoshida Shoin diligently pursued his studies even more fervently, and he learned not only Yamaga style logistics which was hereditary learning for him but also Naganuma-style logistics from samurai Yamada Matasuke and Sato Kansaku. He also learned Western tactics from Iida Inosuke, and Ogino-style gunnery from Morinaga Yaemon.
At the age of 19, on the New Year of 1848 (the 1st year of Kaei era), Yoshida Shoin was released from the supervision of household of Hayashi Masato, Yamada Uemon and Inoue Shichiroujiro and became an independent instructor.
