Nanamagari

Military road from Yamanaka Gotendaira to the summit. It is a very steep road to the castle, and there is no road to the main enclosure other than Nanamagari. Kuruwa is set up in places on the road to solidify the defense. Although it is called Nanamagari, it actually has 11 bends.
The Yamabuki well springs up halfway up the mountain, giving you a glimpse of the impregnable mountain castle.
