Incidentally, if you're unfamiliar with Choki Motobu, here's some info. An S&P kinda guy, in an Okinawan karate master sorta way.
Excerpts from Graham Noble's article in Dragon Times, "Master Choki Motobu: A Real Fighter," available at
http://www.dragon-tsunami.org/Dtimes/Pages/articlec.htm
Motobu was born in Shuri, the old capital of Okinawa, in 1871. He had considerable local fame in Okinawa as a fighter-strongman but it was only after he moved to Osaka in 1921 that he became known in Japanese martial art circles.
What brought Motobu to the attention of the Japanese was his victory over a western boxer in a kind of all-comers challenge match. In the earlier part of this century such bouts were occasionally held in Japan pitting western boxers against judo or jujutsu men, (karate was unknown in Japan around this time). These were not "official" bouts for any sort of legitimate title, but something more like sideshow attractions. The results of such bouts have even been recorded in a few cases. Boxing historians for example are fond of pointing out that, back in 1928 in Yokohama, top bantamweight Packy O'Gatty KO'd a Japanese jujutsu man named Shimakado in 14 seconds. That 14 seconds included the full count, by the way. E. J. Harrison also mentioned in passing a couple of boxing vs. judo shows in his book, The Fighting Spirit of Japan, first published in 1913. Few of the fighters in these events were champions in their sports, but the shows did arouse interest in a certain section of the populace.
Anyway, this was the background to Motobu's victory which so delighted the people back in Okinawa when they heard about it. Soon after Motobu settled in Japan he went to watch a boxing vs. judo show in Kyoto. A boxer taking part beat several judomen rather easily and then issued an open challenge. Moreover, the challenge was issued in a boastful and derogatory way. Choki Motobu, who was sitting in the audience stepped up onto the stage (or ring) and in the ensuing battle he knocked the boxer out-probably with a punch, or series of punches, to the head. That is about as much as we can say about it since no contemporary reports of the fight exist.
As a young man, Choki Motobu's ambition was to become the strongest man in Okinawa. To fulfill this ambition he trained himself every day, lifting stone weights and hitting the makiwara (striking post).
Choki Motobu's idea of a good training session was to go down to Naha's entertainment district and pick fights. This area was well known for street fighting and Motobu picked up valuable experience in this way.
As for training equipment, Motobu stressed the use of makiwara, and also recommended the use of the chishi and sashi, the traditional tools for building the strength of the hands and arms. He also used to practice a crude form of weight training, lifting a heavy stone weighing about 130 lbs. to his shoulders daily.
Motobu was also very agile and quick and he got the nickname"Motobu-saru" (Monkey Motobu) not only because of his rough behavior but also because of his remarkable agility in climbing trees and moving from branch to branch as nimbly as a monkey. In his youth at least he seems to have been a good natural athlete.
He was a good runner too, and Japanese karate expert Hiroyasu Tamae writes of one occasion when Motobu was fighting attackers then ran off, jumped nimbly onto a roof and began tearing off the roofing tiles and throwing them at his assailants, beating them off in this way. Tamae makes the point that Okinawan roof tiles are secured very strongly to withstand typhoons, and it requires powerful hands and arms to tear them loose, but for a man reputed to be the best fighter on Okinawa it still seems a strange way to act.
