Due to the "serious nature of Sekiguchiryu Battou-Jutsu"- All training is via appointment only.

Ken - Jutsu 剣術 

"Sword techniques" and "is used as a universal term generally for sword training". 

Battou - Jutsu 抜刀術 

"the craft of drawing out the sword" and "killing one's enemy simultaneously".

Battou-Jutsu is a specialization component of Kenjutsu.

Battou-Jutsu is often used interchangeably with the terms Iai and Battou. 

It's an older Japanese word for Iai-jutsu.

Battou-Jutsu is a field of Kenjutsu which deals specifically with the rapid drawing and sheathing of a sword. In most cases, a Katana being drawn from its sheath moves with a much greater 

speed and force than when it is being wielded normally. 

Additionally, greater drawing speed gives a swordsman an significant advantage in combat over an opponent whose speed is inferior with a sword already drawn in hand. 

This is due in part to the fact that a katana's sharp blade curves upward against the inside of the sheath, allowing the swordsman to use more strength in drawing it without having to worry about applying extra fine motor skills to control his movements - the sword's path is guided by the sheath while the blade meets no resistance, moving two to three times faster than normal.

Generally, Battou-Jutsu is practiced as a part of a classical Ryu and is closely 

integrated with the tradition of Kenjutsu, normally a Battoujutsu Swordsman will practice with the live-blade katana (Shinken), often they simply drill (kata) alone in Nature. 

This can in turn produce's instinctive behaviour's (muscle memory) to an elevated level of skill, thus unifying the swordsman to the sword, through arduous repeative conditioning over many years. 

The training is for combative effectiveness, through factors such as distancing, timing and targeting. 

Battou-Jutsu differs from modern sport systems of Kendo or Iaido, in a number of ways and due to its extensive history; including the fact that Battou-Jutsu is primarily focused on cutting application for combat effectiveness, the sword usually begins in the scabbard, cutting usually takes place with the extraction of sword from it saya - where with the other arts example Kendo / Iaido the sword is already drawn fully out of the scabbard (saya) and then a cutting action is made.

The Battou-Jutsu swordsmen will often practice with a "real shinken sword " (live blade).

to improve their cutting ability, against soaked straw bamboo & gyoza mats used for (Tameshigiri) 

test cutting to demostrate a swordsman skill & ability.
