Ninjas climbing on a castle wall

Japanese used to do things with their systematized methods and ways calling it gJutsu (p) ". This was not only the case for ninja but all Japanese used to do this. In Japanese, ninjutus (Ep) means ninjasf techniques. There were a lot of ninjutsu, one of them was " To-Jutsu (op) " which teaches how to climb highh but of course any Japanese people did that as a part of their culture, and thatfs where ninjutus is comes from.
As explained before, ninjas were light, they were often less than 60kg. Although not large, ninjas had a surprising finger power and were incredibly well coordinated. It was possible for ninjas who had mastered Tojutsu to clamber up almost anywhere. It can be said that ninjafs skills were as good as professional free-climbing climbers today. They had some tools to climb up castles or stone walls. I am going to introduce " shinobi-kumade (EьF) " as one of the " Toki (o) " , which is the apparatus used to help ninjas climb up to high places.

Shinobi-Kumade

" Shinobi-Kumade (EьF) " is a folding type of equipment. It was composed of several short wooden pipes which were penetrated by a thick rope. On the top of this tool, an iron hook was attached. Ninjas were able to throw the upper pipe above and catch the hook on the top of a target then climb up along the pipes.
The idea of this tool is outstanding, just because this could be used as an easy carry ladder. Shinobi-Kumade were very useful but they had some some weak points, which were that if the pipe was too long then it was not easy for ninjas to carry, also going up high was difficult for them because they needed a lot of strength. In actual fact, those ladders were 3m in length and lighter than 300g in weight, so the use of those ladders was limited to only short walls and depended on the situation. So Shinobi-Kumade was for certain walls and certain purposes.
