Do you know NHK historical drama “Yae no sakura”, or TV drama “The Byakkotai”? Those and many other dramas were filmed here in the Nisshinkan.
The Nisshinkan was the clan school for sons of Aizu samurai, established in 1803. The young Aizu samurai were enrolled in the school at 10 years old, where they learnt various knowledge and martial arts such as Chinese classics, swordsmanship, calligraphy, medical science and the code of the samurai, to be the true Aizu samurai.
There were over 1,300 students at the Nisshinkan, making it one of the largest schools in Japan at that time, until the buildings were burned down at the Boshin Civil War in 1869.
What we see now is the reconstruction of the old buildings according to the draft. The reconstruction includes an astronomical observatory and the oldest swimming pool in Japan, where they practiced swimming in armors. You can also see mannequins in samurai clothes showing what the classes looked like.
This is a good resource to see how young samurai were educated and lived.
Also, a range of workshops and activities are available at the Nisshinkan, such as Zen meditation, Zen lecture, and painting workshops. It would be a nice memory.
