According to legend, Gonnosuke was dissatisfied with this outcome in a batle with Musashi, and retired to Mt. Homan, in what is now Fukuoka Prefecture, in Kyushu, where he engaged in a series of religious austerities, all the while contemplating the reasons for his defeat. Finally, he received "divine" inspiration about a new method of using a staff-like weapon, making it shorter and thinner for more rapid manipulation. He devised a number of techniques for this new weapon, which he called a stick (jo) (as opposed to staff or bo),. Factual documents of the style (ryu) are quite rare. It is said that there is a record at Tsukuba Shrine, in Ibaragi Prefecture, that reports that Gonnosuke was able to defeat Musashi in a rematch. This story is not recorded elsewhere, however, outside fictional novels, and may not be factual.
There are 12 basic techniques, and a total of 64 other in Shinto Muso-ryu jo that are divided into a number of sets, each with a different character. Training is systematic and develops the exponent’s technical skills and psychological abilities, from body movement and weapons handling to the proper use of timing, targeting, and distancing, and intense mental or spiritual training, all to enable the exponent to successfully use the weapons.
Exponents begin their study of jo by learning a set of twelve basic techniques (kihon waza), which contain all of the style’s essential movements. They then proceed through different sets of techniques of stick versus sword(s): omote, chudan, ran-ai, kage, samidare, gohon no midare, and okuden. A final set, the gokui hiden (also called go muso no jo), consists of techniques that are taught only to exponents who have received a menkyo kaiden, the highest level of license in the system.
