The Zen Nihon Karate Kobudo is the modern GOSHIN Japanese school for the five weapons we use
Bo
Nunchaku
Tonfa
Kama
Sai
This modern Kobudo relates to modern Karate
Each of these weapons has KORYO systems from old RYUKYU where they originated
The RYUKYU KOBUDO relates to the RYUKYU KEMPO before that Kempo was refined into the Okinawa TE styles that Karate evolved from
There are other Ryukyu weapons that we do not need to learn, but need to consider, just as we do with the weapons of THAI and SILAT
Most importantly the CONCEPTS and PRINCIPLES behind these weapons, how they came to be used, how the techniques were developed and applied
You will probably never be on a boat fishing with a Trident and find the need to defend yourself from a sudden bandit attack, however the thought behind this use of improvised weapons carries over into any modern situation
Interesting to note, and this can be seen on films such as Gladiator and Spartacus, there were captured Greco Roman warriors of those regions that became gladiators and used the Trident fishing net in the arena
The TOGAKURE uses fishing nets, often in group operations, and this carries into the other two NINJA Ryu
(and those Hunger Games fans will know the Finnick from District 4 the Trident and net and won his Games that year )
The Ryukyu Kobudo list:
TEKKO - a knuckleduster type weapon
TINBE ROCHIN - shield and "spear" though this is actually a short machete like sword
SURIJIN - weighted chain, like a kusarifundo
HANBO the three foot stick and TAMBO the 2 foot stick, like a Kali stick are used
EKU - the oar, like a cricket bat on a Bo staff
SANSETSU KON - the three sectional staff
KUWA - the hoe, both short and long versions
NUNTI BO - a bo with a Sai or Manji sai attached, a form or trident spear
Ryukyu Kempo and Kobudo are the "ancient" Koryo systems from old Ryukyu before it became Okinawa
Nihon Karate and Kobudo are the modern Goshin systems
