A Diary of Kenjutsu Training Journey ~ Reading "Shokoku Kaireki Nichiroku" by a Hagakure Samurai in Saga.

The diary "Shokoku Kaireki Nichiroku" was written by Muta Bun'nosuke(1830-1890) who was Saga-han Samurai. He was son of one of Saga-han Kenjutsu instructors, the school was Tetshujin-ryu. He traveled all over Japan to visit Kenjutsu Dojos between 1853-1855.
This record tells us the system of Kenjutsu training journey in those days.
First, Bun'nosuke needed to get permission for the journey from Saga Han. Saga Han pays expenses of his journey but each Han where he visits Dojo provides room and meals.
Kenjutsu training travelers were called Shugyo-nin. Han had Inn to accept them which was called Shugyo-nin Yado.
Shugyo-nin applies training to Dojos through Shugyo-nin Yado master.
Shugyo-nin meets other Shugyo-nin in the Inn, sometimes they travel together.
Sometimes Dojo master and students visit the Inn to have party after training, or the Inn master took Shugyo-nin to sightseeings.

Martial arts training journey in feudal period Japan is well known but details like that hasn't known.
Excellent book for researchers.
